National Inspection Council for Electrical Installation Contracting a register of approved electricians. It was incorporated on 10 August 1956, and since 1 October 2005, it has been registered as The Electrical Safety Council. Electrical contractors register with the organisation to become approved contractors, meeting the NICEIC's specification of training. If work undertaken by the approved contractor is not up-to-standard, the NICEIC will correct it if necessary. Work is checked by 54 local Area Engineers. Many local authorities only give work to NICEIC-approved electricians. Most electrical items in domestic wiring are controlled from the consumer unit with its residual-current device (RCD), which since 2001 has to be installed.
Electrical equipment in hazardous areas Electrical equipment in hazardous areas In electrical engineering, hazardous locations (sometimes abbreviated to HazLoc, pronounced "Haz·Lōk") are defined as places where fire or explosion hazards may exist due to flammable gases, flammable liquid–produced vapors, combustible liquid–produced vapors, combustible dusts, or ignitable fibers/flyings present in the air in quantities sufficient to produce explosive or ignitable mixtures. Electrical equipment that must be installed in such classified locations should be specially designed and tested to ensure it does not initiate an explosion, due to arcing contacts or high surface temperature of equipment.
