Abstract
An electrical junction box comprises a base and a four-sided peripheral wall with a pair of opposite tubular connectors protruding outwardly from opposite end walls and providing ingress through respective walls, into the box. The box is split into two complementary parts along a line passing through the base and the opposite end walls including the connectors. The base is hinged so that the complementary parts may pivot relative to each other from their normal position of abutment to each other to open the connectors so that conductors within a sheathed cable can be passed through the box from the connectors after severing the surrounding sheath but without severing the cable conductors, and the severed ends of the sheath can be connected to the protruding connectors. This permits making electrical connections to the conductors within the box without severing the conductors. This also provides access to the inside of the sheath to fish additional circuits into the junction box.
