ELECTRICAL SERVICE PANEL
FIELD OF TJHE INVENTION
The present invention relates generally to electrical service panels upon which are mounted electrical items that are necessary for the proper functioning and distπbution of electricity in a building and particularly to a modularly constructed electrical service panel
BACKGROUND OF THE INVENTION
Electrical service panels are well known fixtures that are installed in industry, buildings, homes, schools, offices and the like, upon which are mounted vaπous electrical items that are necessary for the proper functioning and distribution of electricity in the building These items may include switches, lamps, fuses, circuit breakers, contactors, relays and the
There are certain international standards that govern the size of such electrical service panels, such as a DIN CI-4 panel or a DIN CI-46 panel Within a given standard size of panel, an electrician can install a large variety of components This is generally accomplished by mounting different sizes and shapes of brackets, rails and spacers in accordance with the particular electrical components which must be installed in the service panel Thus each installation of an electπcal service panel requires customizing the panel with a plurality of brackets, rails and spacers that are unique for that particular panel This has the disadvantage of being relatively time-consuming and expensive SUMMARY OF THE INVENTION
The present invention seeks to provide an improved electπcal service panel that has a modular construction that eliminates the need for customizing the panel at each installation The present invention provides a plurality of modular bases, brackets, rails and spacers which can be combined to build virtually any kind of service panel required within a standardized panel size, such as a DIN CI-4 panel or a DIN CI-46 panel
There is thus provided in accordance with a preferred embodiment of the present invention an electrical service panel including a base affixable to an electπcal cabinet, and a plurality of pre-formed electπcal mounting hardware elements which can be modularly assembled to the base and which are adapted for mounting thereon electrical components In accordance with a preferred embodiment of the present invention the pre-formed electπcal mounting hardware elements include at least one of brackets, rails, spacers, bus bars and ground and neutral strips
Further in accordance with a preferred embodiment of the present invention the electπcal mounting hardware elements snap on to the base
Still further in accordance with a preferred embodiment of the present invention the base has a plurality of mounting holes formed therein, and the electπcal mounting hardware elements mount on the mounting holes
Additionally in accordance with a preferred embodiment of the present invention the base is formed with a plurality of base mounting holes
In accordance with a preferred embodiment of the present invention the plurality of base mounting holes are spaced and arranged in accordance with a given standardized size for an electrical service panel
Further in accordance with a preferred embodiment of the present invention the plurality of base mounting holes includes an elongate mounting hole
Still further in accordance with a preferred embodiment of the present invention the base and the electπcal mounting hardware elements are constructed of an electrically insulative material
There is also provided in accordance with a preferred embodiment of the present invention a method for constructing an electrical service panel, including providing a base affixable to an electrical cabinet, providing a plurality of pre-formed electπcal mounting hardware elements which can be modulaiiy assembled to the base and which are adapted for mounting thereon electπcal components, selecting a subset of the electrical mounting hardware elements, and securing the subset of the electrical mounting hardware elements to the base in modular fashion
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will be understood and appreciated more fully from the following detailed description, taken in conjunction with the drawings in which
Fig 1 is a simplified pictorial illustration of an electπcal service panel constructed and operative in accordance with a preferred embodiment of the present invention, and
Fig 2 is a simplified pictorial illustration of an electπcal service panel constructed and operative in accordance with another preferred embodiment of the present invention
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Reference is now made to Fig 1 which illustrates an electrical service panel 10 constructed and operative in accordance with a preferred embodiment of the present invention
Electrical service panel 10 preferably includes a base 12 with a plurality of base mounting holes 14 pre-formed therein Mounting holes 14 are preferably spaced and arranged in accordance with a given standardized size for assembling an electrical service panel in an electric cabinet e g , in the illustrated example, a DIN CI-4 panel One or more mounting holes
14 may be elongate, as shown in Fig 1 The elongate holes may be useful in providing ample tolerance to match differing mounting patterns It is appreciated that mounting holes 14 are just one example of mounting accessories which may be provided for affixing base 12 to an electrical cabinet or other mounting surface
A plurality of pre-formed electπcal mounting hardware elements 16 are provided which can be modularly assembled to base 12 Electrical mounting hardware elements 16 may include, for example, one or more rails 18, such as DIN rails, and one or more spacers 20 Electπcal mounting hardware elements 16 are adapted for mounting thereon electrical components, such as switches, lamps, fuses, circuit breakers, contactors, relays and the like (not shown) Base 12 preferably has another plurality of mounting holes 22 formed therein for mounting thereon electπcal mounting hardware elements 16 In a preferred embodiment of the invention, electπcal mounting hardware elements 16 snap on to base 12, such as snapping into mounting holes 22 Base 12 can be a four-sided frame as shown in the illustration, or alternatively can be a pair of strips In general base 12 is any kind of interface structure that is affixable to an electrical cabinet, and upon which elements 16 can be mounted Base 12 and elements 16 are preferably constructed of an electπcally insulative material, such as plastic, thereby providing a high degree of safety Unlike the prior art, the quick, modular construction of the invention obviates the need for electrical drills and other tools for constructing an electπcal service panel
Reference is now made to Fig 2 which illustrates an electπcal service panel 30 constructed and operative in accordance with another preferred embodiment of the present invention Electπcal service panel 30 is preferably constructed similarly to panel 10, with like elements being designated by like numerals In panel 30 the mounting holes 14 are arranged in accordance with a DIN CI-46 panel In panel 30 electrical mounting hardware elements 16 may include for example one or more rails 18, ground and neutral stπps 32, mounting brackets 34 and 36, and three-phase bus bars 38 It is appreciated that these are just one
example of many other kinds of hardware elements which are all within the scope of the invention
It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and descπbed hereinabove Rather the scope of the present invention includes both combinations and subcombinations of the features descπbed hereinabove as well as modifications and variations thereof which would occur to a person of skill in the art upon reading the foregoing description and which are not in the prior art
