Description

    FIELD OF THE INVENTION
  • The present invention relates generally to electrical equipment and, more particularly, to electrical enclosures having configurable electrical panel layouts.
  • BACKGROUND OF THE INVENTION
  • Electrical enclosures, such as, for example, a load center, typically house a plurality of circuit breakers and/or related electrical accessories. Load centers are typically prefabricated to accept a fixed number of a fixed type and size of circuit breaker and/or related electrical accessory. There are a variety of manufacturers that produce different types and sizes of circuit breakers and electrical accessories that “plug-into” the load center. Due to the varying shapes and sizes of the circuit breakers from manufacturer to manufacturer, consumers are forced to purchase and install circuit breakers and electrical accessories into a load center specifically designed and manufactured by the same manufacturer as the load center. Moreover, manufacturers produce several different sizes of circuit breakers to accommodate larger or smaller loads (e.g., higher or lower ampacity circuit breakers). For a prefabricated load center having fixed circuit breaker inputs, a consumer is not always able to install differently sized circuit breakers into the load center, even if the circuit breaker is manufactured by the same party that manufactured the load center.
  • Thus, a need exists for an improved apparatus and method. The present invention is directed to satisfying one or more of these needs and solving other problems.
  • SUMMARY OF THE INVENTION
  • The present disclosure is directed to providing a customizable load center (hereinafter referred to as “CLC”). The CLC is configurable by an original equipment manufacturer (herein after referred to as “OEM”), an electrician, an end user, etc. to accept a plurality of different makes, models, sizes, and types of circuit breakers and related electrical accessories. The CLC includes an outer housing for mounting the CLC into a building, such as a residential house. The housing has various inputs/outputs to receive electrical wires. For a CLC in a typical single family home, the housing is mounted between two studs in a wall. The housing receives one or more live electrical lines from an electrical utility company. The live electrical lines electrically couple with one or more electrical busbars. The busbars are insulated from the housing and are rigidly positioned within the housing. The busbars supply electricity to the plurality of circuit breakers and related electrical accessories that are plugged into the CLC.
  • The present disclosure includes a plurality of insulating inserts that are positioned adjacent to the one or more busbars. The insulating inserts can be coupled to the one or more busbars, to the housing, or to both.

  • DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
  • Although the invention will be described in connection with certain aspects and/or embodiments, it will be understood that the invention is not limited to those particular aspects and/or embodiments. On the contrary, the invention is intended to cover all alternatives, modifications, and equivalent arrangements as may be included within the spirit and scope of the invention as defined by the appended claims.
  • Referring to FIG. 1, an electrical enclosure or customizable load center 100 is shown according to some embodiments of the present disclosure. The customizable load center 100 is referred to herein as CLC 100 for short. According to some embodiments, the CLC 100 includes a housing 110. The housing 110 can be made of a variety of materials including metal, plastic, fiberglass, etc. According to some embodiments, the housing 110 includes a hinged door (not shown) or other means of sealing or covering the contents of the CLC 100. The housing 110 can also include an insulating sheet or pad 112 to cover all of or a portion of an interior of the housing 110. The insulating pad 112 is configured to electrically insulate the contents of the CLC 100 from items outside the housing 110 (e.g., metal wall studs, screws, wires, etc.).
  • According to some embodiments, the housing 110 is configured to be installed or attached between two wall studs in a building or residential house. The width of the housing 110 is limited to an inner spacing between the wall studs (e.g., about 14.5 inches±2 inches or about 18 inches±2 inches). Such a width limitation can affect the design and overall dimensions of the housing 110, which in return affects the number of circuit breakers and/or related electrical accessories that can be coupled within the housing 110. For example, when the outer width of the housing 110 is designed to fit between two wall studs that are positioned, for example, sixteen inches on center, the number of average-sized circuit breakers that can be coupled side-to-side across the width of the housing 110 is limited to about two average-sized circuit breakers. As additional electrical and mechanical parts and/or components are included into circuit breaker housings, the thicknesses of the circuit breaker housings can vary. Thus, the CLC 100 of the present disclosure is configurable to accept a plurality of differently sized circuit breakers and/or related electrical accessories.
  • The CLC 100 includes a first and a second busbar 120 a-b, a plurality of insulating inserts 130 a-e, and a plurality of busbar connectors 140 a-c. While specific numbers of busbars 120 a-b, insulating inserts 130 a-e, and busbar connectors 140 a-c are shown in FIG. 1, it is contemplated that the CLC 100 can include any number or amount of busbars 120, insulating inserts 130, and busbar connectors 140. For example, in some embodiments, the CLC 100 includes one busbar 120, one insulating insert 130, and one busbar connector 140. For another example, the CLC 100 includes three busbars 120, twenty insulating members 130, and fifteen busbar connectors 140.
  • The first and the second busbars 120 a-b are formed from any electrical conducting material, as is known in the art, such as copper. The busbars 120 a-b are positioned within the housing 110 such that the busbars 120 a-b are electrically insulated from the housing 100. According to some embodiments, the busbars 120 a-b are positioned between and held rigidly in place by a first block 114 and a second block 116. The first and the second blocks 114 and 116 are attached or coupled to the housing 110 and/or the insulating pad 112 such that the first and the second blocks 114 and 116 aid in electrically insulating the busbars 120 a-b from the housing 110. The second block 116 includes a first terminal 117 a and a second terminal 117 b. The housing 110 includes one or more apertures (not shown) positioned adjacent to the terminals 117 a-b and configured to receive electrical supply lines 119 a-b. The first and the second terminals 117 a-b include respective attachment means, such as, for example, a lug, screw, or bolt 118 a-b to aid in the electrical and physical attachment of the electrical supply wires 119 a-b. The electrical supply wires 119 a-b are electrically and physically coupled with the respective terminals 117 a-b via the screws 118 a-b to supply electricity to the first and the second busbars 120 a-b, respectively. Various other methods of positioning the busbars 120 a-b within the housing 110 and electrically coupling the busbars 120 a-b to the supply wires 119 a-b are contemplated.
  • The first busbar 120 a includes a plurality of apertures 122 a equidistantly positioned along a length of the first busbar 120 a. Similarly, the second busbar 120 b includes a plurality of apertures 122 b equidistantly positioned along a length of the second busbar 120 b. The distance, D, between the apertures 122 a positioned along the length of the first busbar 120 a and the distance, D, between the apertures 122 b positioned along the second busbar 120 b are equal. For example, the distance, D, from the center of one aperture to the center of an immediately adjacent aperture on the first busbar 120 a is equal to the distance, D, from the center of one aperture to the center of an immediately adjacent aperture on the second busbar 120 b, as shown in FIG. 1. According to other embodiments, a distance between the apertures 122 a positioned along the length of the first busbar 120 a is an integer multiple of a distance between the apertures 122 b positioned along the second busbar 120 b. According to still other embodiments, a distance between the apertures 122 b positioned along the length of the second busbar 120 a is an integer multiple of a distance between the apertures 122 a positioned along the first busbar 120 b.
  • The apertures 122 a-b can be circular, oval, square, rectangular, or any other consistent shape from aperture to aperture. Alternately, the apertures can be elongated slots (not shown) having a length and a width, wherein the length of the slots is positioned either parallel to the length of the busbars 120 a-b or perpendicular to the length of the busbars 120 a-b. In this example, the slots are positioned such that at least a portion of the busbars 120 a-b is formed in the shape of a comb (not shown). Alternately, instead of the plurality of apertures 122 a-b, the busbars 120 a-b each include a plurality of equidistantly positioned attachment surfaces or areas, registration positions, dimples, divots, channels, cavities, lumps, indents, etc.
  • Now referring to FIGS. 1 and 2A, each of the plurality of insulating inserts 130 a-e is configured to be positioned within the housing 110 and adjacent to the busbars 120 a-b. Each of the insulating inserts 130 a-e is configured to be coupled to the first busbar 120 a, to the second busbar 120 b, or to both busbars 120 a-b. Alternatively, each of the insulating inserts 130 a-e can be configured to be coupled to the housing 110, the insulating pad 112, and/or the busbars 120 a-b.
  • Each of the plurality of insulating inserts 130 a-e includes a body 131 a-e. The body 131 a-e can be formed from any electrically insulating material, such as, for example, plastic. The body 131 a-e can be formed as a single integrated part or a collection of parts. For example, the body 131 a-e can be formed via a molding process, an extrusion process, or a combination thereof. Each of the bodies 131 a-e has a length, L and a width, W. The length, L of each of the insulating inserts 130 a-e is the same from insert to insert. Alternately, the length, L can vary from insert to insert (not shown). Likewise, the width, W of each of the insulating inserts 130 a-e can vary from insert to insert. As shown in FIG. 1, the plurality of insulating inserts 130 a-e include insulating inserts having at least three different widths, W1, W2, and W3. By way of example, W1 is three-quarters of an inch, W2 in half an inch, and W3 is one inch. It is contemplated that the plurality of insulating inserts 130 a-e can include insulating inserts having a variety of other or additional widths, such as, for example, one-sixteenth of an inch, one-eighth of an inch, one-third of an inch, two-thirds of an inch, two inches, or corresponding metric units, etc. The available widths, W of the insulating inserts 130 a-e correspond to widths of circuit breakers and related electrical accessories available for attachment to the CLC 100.
  • The width, W of each of the plurality of insulating inserts 130 is an integer multiple of the distance, D between the equidistantly positioned apertures of the first busbar 120 a, the second busbar 120 b, or both the first and the second busbars 120 a-b. For example, for a distance, D of one-eighth of an inch between the apertures 122 a-b positioned along the first and the second busbars 120 a-b, the width, W of the insulating inserts can be one-eight of an inch, one-quarter of an inch, half of an inch, three-quarters of an inch, one inch, two inches, etc. A distance, D of one-eighth of an inch allows for side-by-side positioning of the plurality of insulating inserts 130 a-e having distinct integer multiple widths along the length of the busbars 120 a-b.
  • The body 131 further includes a divider 137. The divider 137 is positioned to aid in electrically insulating the first busbar 120 a from the second busbar 120 b. The divider 137 can be positioned such that a bottom surface of the divider 137 rests on or contacts the insulating pad 112. The divider 137 further provides rigidity to the insulating insert 130. The divider 137 can be formed as an integral portion of the body 131 or as a separate part coupled thereto.
  • The insulating insert 130 further includes coupling means 138 and 139. As shown in FIG. 2A, the first coupling means 138 and the second coupling means 139 are both resilient hooks or clips. The resilient clips 138, 139 are configured to bend and snap onto and around the busbars 120 a-b to removably couple the insulating insert 130 to the busbars 120 a-b. For example, an OEM configuring the CLC 100 can position the insulating insert 130 above the busbars 120 a-b and press the insulating insert 130 into contact with the busbars 120 a-b such that the resilient clips 138, 139 bend outward and snap into place around the busbars 120 a-b, thereby holding the insulating insert 130 in position adjacent to the busbars 120 a-b. To remove the insulating insert 130, the resilient clips 138, 139 can be bent outward while pulling the insulating insert 130 away from the busbars 120 a-b.
  • Referring to FIG. 2B, an alternative apparatus and method of coupling and decoupling an insulating insert 130′ is shown and described. As shown in FIG. 2B, the insulating insert 130′ includes a body 131′ and coupling means 138′ and 139′. The first coupling means 138′ is the same as, or similar to, the first coupling means 138 of FIG. 2A. The second coupling means 139′ includes a pin 139 a′, a spring 139 b′, and a support structure 139 c′. The pin 139 a′ is supported by and moveably attached to the support structure 139 c′. The spring 139 b′ is positioned within the support structure 139 c′ to bias the pin 139 a′ in the direction of arrow A to secure the insulating insert 130′ in a locked positioned (shown). To remove the insulating insert 130′ from the locked position, the pin 139 a′ is pulled in a direction opposite to the direction of arrow A, thereby freeing the insulating insert 130′ for removal. Various other methods and apparatuses for coupling and decoupling the insulating inserts 130 and 130′ to the busbars 120 a-b and/or the housing 110 are contemplated.
  • Referring back to FIGS. 1 and 2A, the plurality of insulating inserts 130 a-e each includes one removable portion 132. Alternately, as shown in FIG. 1, the plurality of insulating inserts 130 a-e each include two removable portions 132 (e.g., removable portions 132 a,b,c,d,e). The removable portions 132 are configured to be removed from the body 131 of the respective insulating inserts 130 a-e to form apertures 132′ in the body 131. The formed apertures 132′ can be of a variety of shapes and sizes including, square, rectangle, circular, oval, etc. For example, the insulating insert 130 d is shown as having one of the removable portions 132 d intact and the other removable portion removed from the body 131 d, thereby forming a rectangular aperture 132 d′. The rectangular aperture 132 d′ formed in the body 131 d allows access to the underlying busbar 120 b for physical and electrical attachment of one of the busbar connectors 140.
  • The removable portions 132 are cut-out sections configured to be snapped-off of the body 131. The removable portions 132 can be pre-stressed and/or pre-cut to facilitate removal from the body 131. The removable portions 132 are sufficiently attached to the body 131 to prevent accidental removal of the removable portion 132. In such examples, a piece of tape can be used to further maintain the removable portion's 132 attachment to the body 131.
  • Each of the plurality of insulating inserts 130 a-e optionally includes a first mounting rail 133 and a second mounting rail 134. The mounting rails 133, 134 can be formed as an integral portion of the body 131 or as an independent parts coupled thereto. The mounting rails 133, 134 can be made of plastic and/or metal. The mounting rails 133, 134 are positioned to receive respective mounting clips of two different circuit breakers attached to the insulating insert 130, described below and shown in FIGS. 3 and 4. The mounting rails 133, 134 provide additional support and/or attachment rigidity of the circuit breakers to the insulating inserts 130 a-e. The mounting rails 133, 134 aid in aligning and/or positioning respective jaw members of the two circuit breakers with the busbar connector 140, also described below and shown in connection with FIGS. 3 and 4. While the insulating members 130 a-e are each shown as including the mounting rails 133 a-e, 134 a-e, it is contemplated that the insulating inserts 130 a-e do not necessarily include the mounting rails 133 a-e, 134 a-e. In such embodiments, the circuit breakers can be designed to merely attach to the busbar connectors 140, or the circuit breakers can be configured to attach to the housing 110, which can include mounting rails similar to the mounting rails 133 and 134.
  • Each of the plurality of insulating inserts 130 further includes a first phase barrier 135 and a second phase barrier 136. The first phase barrier 135 extends away from a first side of the body 131 and the second phase barrier 136 extends away from a second opposing side of the body 131, as shown in FIG. 1. The phase barriers 135 and 136 can be formed as an integral portion of the body 131 or as independent parts coupled thereto. The phase barriers 135 and 136 can be made of any electrically insulating material, such as, for example, plastic. Generally, the phase barriers 135 and 136 are positioned to insulate a first circuit breaker from a second circuit breaker attached within or coupled to the CLC 100. The phase barriers 135 and 136 insulate a first jaw member of a first circuit breaker from a second jaw member of a second circuit breaker when the second circuit breaker is positioned adjacent to the first circuit breaker within the CLC 100. For example, the second phase barrier 136 a and the first phase barrier 135 b are positioned to insulate a first circuit breaker coupled to first insulating insert 130 a and the first busbar connector 140 a from a second circuit breaker coupled to the second insulating insert 130 b and the second busbar connector 140 b. For another example, the second phase barrier 136 b and the first phase barrier 135 c are positioned to insulate a first circuit breaker coupled to the second insulating insert 130 b and the second busbar connector 140 b from a second circuit breaker coupled to the third insulating insert 130 c and the third busbar connector 140 c.
  • As described above, removal of the removable portion 132 from the insulating insert 130 provides access to the underlying busbar 120 a-b for attachment of one of the busbar connectors 140. Each of the plurality of busbar connectors 140 a-c has a first end 141 a and a second end 141 b, as shown in FIG. 2A. The first end 141 a is configured to be coupled to the first or the second busbar 120 a-b via one of the apertures 122 a-b, respectively. The busbar connector 140 is physically and electrically coupled to the first busbar 120 a through the aperture 132′ formed in the insulating insert 130 using an attachment means 142 a-c. As shown in FIG. 2A, the attachment means 142 can be a self-tapping screw, a regular screw, a bolt, etc. The attachment means 142 secures the busbar connector 140 to the first busbar 120 a such that the second end 141 b is configured to receive and/or be coupled to one or more jaw members of one or more circuit breakers, which is described below in reference to FIGS. 3 and 4.
  • As shown in FIG. 1, the busbar connectors 140 a-c alternate couplings between the first and second busbars 120 a-b. Such a configuration can be used to equally distribute a load between the busbars 120 a-b. Other coupling configurations are contemplated. The busbar connectors 140 are shown as having an “L” shape. Other shapes are contemplated, such as, for example, a “Z” shape, a “T” shape, etc.
  • Now referring to FIG. 3, the insulating insert 130 of FIG. 2A is shown with a first circuit breaker 150 a and a second circuit breaker 150 b at least partially attached. The circuit breakers 150 a-b are not shown in cross section for illustrative purposes to show how the first and the second circuit breakers 150 a-b attach to the busbar connector 140. The circuit breakers 150 a-b each includes a jaw member 152 a-b, a mounting clip 154 a-b, and a pair of phase barrier recesses 156 a-b, one recess being on a first side (shown) of each circuit breaker 150 a-b and the other recess being on a second opposing side (not shown) of each circuit breaker 150 a-b.
  • Referring to the second circuit breaker 150 b, attachment of the second circuit breaker 150 b to the insulating insert 130 begins by attaching the second mounting clip 154 b onto the second mounting rail 134. Then the second circuit breaker 150 b can be rotated to attach the second jaw member 152 b to the busbar connector 140. As the second circuit breaker 150 b is rotated, the second recess 156 b that is on the second opposing side of the second circuit breaker 150 b (not shown) is positioned to accept and/or register with the first phase barrier 135. Referring to the first circuit breaker 150 a, the first circuit breaker 150 a is shown in the attached or connected position, such that (i) the mounting clip 154 a is attached to the first mounting rail 133, (ii) the jaw member 152 a is attached to the busbar connector 140, and (iii) the first recess 156 a that is on the second opposing side of the first circuit breaker 150 a (not shown) is completely registered with the first phase barrier 135.
  • Now referring to FIG. 4, a side elevation view of the insulating insert 130 of FIG. 2A is shown with the first circuit breaker 150 a and the second circuit breaker 150 b attached.
