Patent ID: 8035040

Claim:
An electrical junction box comprising: a casing having an upper end part; an electric current sensor disposed in the upper end part of the casing, the electric sensor defining a through-hole; a detecting bus bar having opposite ends, the detecting bus bar penetrating the through-hole in the electric current sensor so that the opposite ends of the detecting bus bar project from the through-hole, the opposite ends being provided with bolt holes; an input side bus bar and an output side bus bar that are disposed below the opposite ends of the detecting bus bar and defining bolt holes to be communicated with the bolt holes in the detecting bus bar; and bolts inserted downward into the bolt holes of the detecting bus bar and the bolt holes of the input side bus bar and the output side bus bar so that the detecting bus bar is secured to the input and output side bus bars while the bolt holes are communicated with one another, wherein the electric current sensor is configured to be removed from the casing by releasing the bolts.
