There is provided an enclosure that encapsulates a current transformer by utilizing a snap together design while allowing for electrical coupling between the transformer and external wiring. Two housing members will snap together while capturing the transformer in a rigid fashion to avoid excess vibration or friction, which could fatigue the transformer's wiring.

Protective snap-together enclosure for current transformers

A receptacle is provided which snaps into and seals an opening in a circuit breaker case. A pair of opposed, resilient tabs hold the receptacle within the opening, and substantially prevent withdrawal of the receptacle from the opening. A pair of resilient legs form a flexible U-shaped notch which is adapted to receive and hold a male member attached to a circuit breaker access cover. Therefore screws are not needed for securing the circuit breaker access cover to the circuit breaker case, and the cover is easily removed and replaced any number of times without the use of special tools.
