Apparatus and method are provided for testing continuity of a ring circuit of an electricity distribution system, the ring circuit including at least a first conductor connecting, in a ring configuration, a source of electricity to a plurality of accessories. The apparatus includes: a switch arranged to cause a break in the ring circuit at a location in the ring circuit, the break resulting in a first end and a second end of the ring circuit at the location; a detector for measuring the relative voltage between the first end and the second end of the ring circuit; and an indicator which indicates, responsive to the detector detecting a relative voltage between the first end and the second end of the ring circuit, that there is a lack of continuity in the ring circuit.
