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.
Abbreviated dialing Abbreviated dialing Abbreviated dialing is the use of a very short digit sequence to reach specific telephone numbers, such as those of public services. The purpose of such numbers is to be universal, short, and easy to remember. Typically they are two or three digits. Carriers refer to the shortened number sequences as "abbreviated dialing codes" (ADCs). Unlike SMS shortcodes, they are generally not automatically synchronized across carriers. ADCs are provisioned separately for mobile networks versus landline networks. The most commonly known examples are emergency telephone numbers such as 9-9-9, 1-1-2 and 9-1-1.
