Abstract

A switchboard is for a power distribution system having a number of electrical lines. The switchboard includes: an enclosure assembly having a chassis; a switching assembly including a plurality of circuit breakers each coupled to the chassis, each of the circuit breakers having a number of terminal lugs structured to be electrically connected to a corresponding one of the electrical lines; and an isolating assembly including a plurality of isolating apparatus, at least one isolating apparatus being coupled to one of the plurality of circuit breakers. The isolating apparatus separates the number of terminal lugs of the one circuit breaker from the number of terminal lugs of each of the other circuit breakers.

First claim

What is claimed is:

1. A switchboard for a power distribution system comprising a number of electrical lines, said switchboard comprising:
an enclosure assembly comprising a chassis;
a switching assembly comprising a plurality of circuit breakers each coupled to said chassis, each of said circuit breakers comprising a number of terminal lugs structured to be electrically connected to a corresponding one of said electrical lines; and
an isolating assembly comprising a plurality of isolating apparatus, at least one isolating apparatus of said plurality of isolating apparatus being coupled to one of said plurality of circuit breakers,
wherein said at least one isolating apparatus separates the number of terminal lugs of said one of said plurality of circuit breakers from the number of terminal lugs of each of the other of said plurality of circuit breakers; wherein said enclosure assembly further comprises a frame coupled to said chassis; wherein said barrier member is structured to cover the number of terminal lugs of said one of said plurality of circuit breakers in order to prevent inadvertent access thereto; wherein said at least one isolating apparatus further comprises a first mounting bracket and a second mounting bracket each coupled to said frame; wherein said barrier member is coupled to each of said first mounting bracket and said second mounting bracket and extends therebetween; wherein said frame comprises a distal edge portion; and wherein said first mounting bracket, said second mounting bracket, and said barrier member extend from proximate said one of said plurality of circuit breakers to proximate said distal edge portion.

2. The switchboard of claim 1 wherein said enclosure assembly further comprises a deadfront coupled to said frame; and wherein said barrier member is disposed between said deadfront and said one of said plurality of circuit breakers.

3. The switchboard of claim 1 wherein said first mounting bracket and said second mounting bracket are each concave facing away from one another.

4. The switchboard of claim 1 wherein said barrier member is removably coupled to said first mounting bracket and said second mounting bracket.

5. The switchboard of claim 1 wherein said switching assembly further comprises a bus bar mechanically coupled and electrically connected to said plurality of circuit breakers; wherein said at least one isolating apparatus further comprises a second barrier member extending between said first mounting bracket and said second mounting bracket; and wherein said second barrier member is structured to prevent inadvertent access to said bus bar.

6. The switchboard of claim 5 wherein said second barrier member comprises a first wall, a second wall, and a third wall extending between said first wall and said second wall; and wherein said third wall is disposed perpendicular to said first wall, said second wall, and said barrier member.

7. The switchboard of claim 1 wherein said plurality of circuit breakers comprises a main circuit breaker and a plurality of branch circuit breakers each electrically connected to said main circuit breaker; and wherein said at least one isolating apparatus is a plurality of isolating apparatus each coupled to a corresponding one of said plurality of branch circuit breakers.

8. The switchboard of claim 7 wherein said frame comprises a first sidewall, a second sidewall disposed opposite and parallel to said first sidewall, and a third sidewall extending between and being disposed perpendicular to each of said first sidewall and said second sidewall; wherein said main circuit breaker has a number of terminal lugs facing said third sidewall; and wherein each of said plurality of branch circuit breakers has a number of terminal lugs facing said first sidewall.

9. The switchboard of claim 7 wherein said frame comprises a first sidewall and a second sidewall disposed opposite and parallel to said first sidewall; wherein said main circuit breaker has a number of terminal lugs facing said first sidewall; and wherein each of said plurality of branch circuit breakers has a number of terminal lugs facing said second sidewall.

10. A switchboard for a power distribution system comprising a number of electrical lines, said switchboard comprising:
an enclosure assembly comprising a chassis;
a switching assembly comprising a plurality of circuit breakers and a number of bus bars electrically connected to said plurality of circuit breakers, each of a said plurality of circuit breakers being coupled to said chassis and being structured to be electrically connected to a corresponding one of said electrical lines, and
an isolating assembly comprising a number of insulative blocking members each coupled to said chassis,
wherein said number of insulative blocking members are cooperatively structured to isolate said number of bus bars from an interior of said switchboard; wherein said number of insulative blocking members comprises a first blocking member and a number of other blocking members disposed perpendicular to said first blocking member; and wherein said first blocking member is disposed perpendicular to said number of bus bars.

11. The switchboard of claim 10 wherein said plurality of circuit breakers comprises a main circuit breaker and a plurality of branch circuit breakers electrically connected to said main circuit breaker; wherein each of said number of bus bars comprises a first distal end and a second distal end disposed opposite said first distal end; wherein each respective first distal end is disposed proximate said main circuit breaker; and wherein each respective second distal end is disposed between said first distal end and said first blocking member.

12. The switchboard of claim 10 wherein said isolating assembly further comprises a barrier member coupled to said chassis; wherein said barrier member comprises a first wall, a second wall, and a third wall extending between and being disposed perpendicular to said first wall and said second wall; wherein said plurality of circuit breakers comprises a main circuit breaker and a plurality of branch circuit breakers electrically connected to said main circuit breaker; and wherein said main circuit breaker has a number of terminal lugs disposed between said first wall and said second wall.

13. The switchboard of claim 12 wherein said isolating assembly comprises a second barrier member disposed coplanar with said first wall; and wherein said second barrier member extends from proximate said main circuit breaker to proximate one of said plurality of branch circuit breakers.

14. The switchboard of claim 10 wherein each of said number of insulative blocking members is made of a glass polymer material.

15. A switchboard for a power distribution system comprising a number of electrical lines, said switchboard comprising:
an enclosure assembly comprising a chassis;
a switching assembly comprising a plurality of circuit breakers and a number of bus bars electrically connected to said plurality of circuit breakers, each of said plurality of circuit breakers being coupled to said chassis and being structured to be electrically connected to a corresponding one of said electrical lines, and
an isolating assembly comprising a number of insulative blocking member each coupled to said chassis,
wherein said number of insulative blocking members are cooperatively structured to isolate said number of bus bars from an interior of said switchboard; wherein said number of insulative blocking members comprises a first blocking member and a number of other blocking members disposed perpendicular to said first blockin
