ELECTROCUTION in the workshop and bome is unfortunately not rare. For many years, fuses and circuit breakers have been used to protect electrical equipment from excessive current flow, but they offer no protection against electrocution. In Soutb Africa, an earth leakage relay (operating on current balance) has been develope.d to be placed at tbe power inlet of tbe bome, and it bas been shown that with leakage currents to earth of 10 mA and upwards, the relay will cut off the current flow witbin 20 to 40 m.sec. This equipment is now being used elsewhere, and especially in Queensland in this country. A portable type for use with power tools is also available.
