Patent ID: 8564280

Claim:
An electricity meter comprising: a single current sensor comprising a toroidal coil having an inner bore extending substantially centrally therethrough, the inner bore having a first end and a second end; a first current conductor and a second current conductor, wherein each of the first and second current conductors has a first end and a second end, the first end of each current conductor forming a respective one of a pair of line-side or load-side blades of the meter; and a disconnect switch having a pair of moveable contacts and a pair of fixed contacts, one of the pairs of contacts being electrically connected to respective second ends of the first and second current conductors, and the other pair of contacts forming opposite load-side or line-side blades of the meter, wherein the first current conductor passes through the inner bore of the current sensor in a first direction relative to its line-side blade and the second current conductor passes through the inner bore of the current sensor in a substantially opposite direction relative to its line-side blade, such that during operation of the meter electrical current passing through the first and second current conductors passes through the inner bore of the current sensor in a same direction.
