Abstract

A terminal block, by means of which a multi-core cable is connected to several drop wires, may be repaired by positioning an adapter over its binding posts. The adapter has an aperture into which a non-stripped, non-split, multi-core drop wire can be inserted such that one core of the drop wire is adjacent one binding post. Caps are then screwed onto the binding posts to make contact with respective cores, preferably by cutting through insulation of the drop wire. The adapter may be adjustable to suit different sizes of terminal block.
