Patent ID: 7511229

Claim:
An electrical system, comprising: a. a first sensor module, comprising: i. a first portion of material with a second portion of material being disposed at an angle to the first portion; ii. at least one post coupled to the second portion, the post having an opening therethrough oriented at an angle to the second portion; and iii. at least one current transformer coupled to the post, the current transformer having an aperture aligned with the post opening and the post adapted to insulate the current transformer from a wire of the electrical system passing through the post opening; b. an electrical panel, the first sensor module being coupled to the electrical panel; c. a plurality of circuit breakers coupled to the electrical panel at an incremental spacing relative to each other and a plurality of current transformers aligned with at least a portion of the plurality of circuit breakers at the incremental spacing to allow wiring to pass in alignment from the circuit breakers through the current transformers; and d. a second sensor module interchangeable with the first sensor module and adapted to be mounted end-to-end adjacent the first module, wherein the molded portion of each sensor module comprises a recessed portion on at least one end of each module, the recessed portion on the first sensor module being adapted to laterally align with the recessed portion on the second sensor module and maintain alignment of an overlapping opening in each sensor module at the incremental spacing of corresponding circuit breakers.
