Electrical wiring

Electrical wiring is an electrical installation of <a href="/facts/Electrical_cable/Dhzlz5hn">cabling</a> and associated devices such as <a href="/facts/Switch/vqbNDgYm">switches</a>, <a href="/facts/Distribution_board/dlKaDFU8">distribution boards</a>, sockets, and light fittings in a structure.
Wiring is subject to safety standards for design and installation. Allowable <a href="/facts/Wire/yyy05H1S">wire</a> and <a href="/facts/Electrical_cable/Dhzlz5hn">cable</a> types and sizes are specified according to the circuit operating <a href="/facts/Voltage/EN2po6N2">voltage</a> and <a href="/facts/Electric_current/Dc1xdnUX">electric current</a> capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals.
Associated circuit protection, control, and distribution devices within a building's wiring system are subject to voltage, current, and functional specifications. Wiring safety codes vary by locality, country, or region. The <a href="/facts/International_Electrotechnical_Commission/hSK0kjwI">International Electrotechnical Commission</a> (IEC) is attempting to harmonise wiring standards among member countries, but significant variations in design and installation requirements still exist.
