Electrical wiring in the United Kingdom lawnmower does it need an RCD?" The risk of electrical shock on construction sites can be reduced by several measures, including reduction of the normal 230 volt distribution voltage to 110 volts for electrical lighting and power tools. By using a centre-tapped transformer, each conductor of the circuit is only at 55 volts with respect to earth. This reduces the chance of dangerous electrical shock when using power tools in wet locations. Where 230 volts must be used, a residual current device (RCD) can be used to detect small leakage currents and automatically isolate faulty equipment. In sites where hazardous
Communications, Electrical and Plumbing Union of Australia the Australian Council of Trade Unions. Communications, Electrical and Plumbing Union of Australia The Communications, Electrical and Plumbing Union of Australia (CEPU) is a trade union in Australia. Its full name is the Communications, Electrical, Electronic, Energy, Information, Postal, Plumbing and Allied Services Union of Australia as it represents workers in all of these industries. CEPU is an amalgamation of three separate unions, which are divisions of CEPU, namely the: Whilst the CEPU is technically one federally registered union, each of the above divisions act largely autonomously sharing resources when needed. At a state level many of the unions exist
