Abstract
Circuit interrupter devices have a first housing with a circuit interrupter, a second housing coupled to the first housing, a ground fault circuit and current transformer in the second housing. The current transformer has an open channel. The circuit interrupter devices also include at least one power conductor having a rigid or semi-rigid body with opposing first and second end portions extending between the first and second housings. The second end portion of the at least one power conductor extends through the open channel in the current transformer and terminates in a breaker load collar(s).
Claims15
A circuit interrupter device, comprising:
- a first housing comprising a circuit interrupter;
- a second housing coupled to the first housing;
- at least one load collar in the second housing;
- a current transformer in the second housing, wherein the current transformer has an open channel;
- at least one power conductor having a rigid or semi-rigid body with opposing first and second end portions extending between the first and second housings, wherein the second end portion extends through the open channel in the current transformer into the at least one load collar;
- and
- a support member coupled to the first housing and also coupled to a segment of the at least one power conductor,
- wherein the support member is inclined and extends external of the first housing into the second housing.
