Abstract
An electrical distribution enclosure includes an electrically insulated panel defining an access portion of the enclosure and a load portion of the enclosure; at least one electrically insulated compartment panel positioned within the access portion; and two or more compartments within the access portion, each compartment separated from an adjacent compartment by an electrically insulated compartment panel, each of the two or more compartments having a front-accessible neutral connection, at least one front-accessible phase connection and a at least rear phase connection.
Claims20
An electrical distribution enclosure comprising:
- an electrically insulated panel separating an access portion of the electrical distribution enclosure from a load portion of the electrical distribution enclosure;
- at least one electrically insulated compartment panel positioned within the access portion;
- and
- two or more compartments within the access portion, each of the two or more compartments separated from an adjacent one or ones of the compartments by at least one of the electrically insulated compartment panel, each of the two or more compartments having:
- a front-accessible neutral connection disposed at a front portion of each of the two or more compartments,
- at least one front-accessible phase connection disposed at the front portion of each of the two or more compartments, and
- at least one rear phase connection disposed at a rear portion of each of the two or more compartments, the at least one rear phase connection electrically coupled to a corresponding one of the at least one front-accessible phase connection.

An electrical distribution assembly comprising:
- a first enclosure comprising at least one electrical switch and a neutral connection, the electrical switch having at least one load connection;
- and,
- a second enclosure comprising:
- an electrically insulated panel separating an access portion of the second enclosure from a load portion of the second enclosure;
- at least one electrically insulated compartment panel positioned within the access portion;
- and
- two or more compartments within the access portion, each of the two or more compartments separated from an adjacent one or ones of the compartments by at least one of the electrically insulated compartment panel, each of the two or more compartments having:
- a front-accessible neutral connection disposed at a front portion of each of the two or more compartments,
- at least one front-accessible phase connection disposed at the front portion of each of the two or more compartments, and
- at least rear phase connection disposed at a rear portion of each of the two or more compartments, the at least one rear phase connection electrically coupled to a corresponding one of the at least one front-accessible phase connection
- wherein at least one electrical switch of the first enclosure is connected to the rear phase connection of the second enclosure, and the neutral connection of the first enclosure is connected to the front-accessible neutral connection of the second enclosure.
8 more elements
A method of connecting a downstream branch connection to an electrical switch comprising:
- opening the electrical switch, the electrical switch positioned within a first enclosure, the electrical switch having at least one load connection, the first enclosure having a neutral connection;
- providing a second enclosure comprising an electrically insulated panel separating an access portion of the second enclosure from a load portion of the second enclosure, at least one electrically insulated compartment panel positioned within the access portion, the at least one electrically insulated compartment panel extending from the electrically insulated panel, the at least one electrically insulated compartment panel separating two or more compartments, each of the two or more compartments having:
- a front-accessible neutral connection disposed at a front portion of each of the two or more compartments,
- at least one front-accessible phase connection disposed at the front portion of each of the two or more compartments, and
- at least one rear phase connection disposed at a rear portion of each of the two or more compartments, the at least one rear phase connection electrically coupled to a corresponding one of the at least one front-accessible phase connection;
- connecting one or more cables to the neutral connection of the first enclosure and at least one of the at least one front-accessible neutral connection of the second enclosure, and,
- connecting the one or more cables to the at least one load connection of the electrical switch and at least one of the at least one rear phase connection.
