The Complete Guide to Electrical Wiring | EEPElectrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current 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 specification. Wiring safety codes vary by locality, country or region.

Electrical wiring in the United Kingdom is commonly understood to be an electrical installation for operation by end users within domestic, commercial, industrial, and other buildings, and also in special installations and locations, such as marinas or caravan parks. Electrical wiring is ultimately regulated to ensure safety of operation, by such as the Building Regulations , currently legislated as the Building Regulations , which lists "controlled services" such as electric wiring that must follow specific directions and standards, and the Electricity at Work Regulations The detailed rules for end-use wiring followed for practical purposes are those of BS Requirements for Electrical Installations. IET Wiring Regulations , currently in its 18th edition, which provide the detailed descriptions referred to by legislation. UK electrical wiring standards are largely harmonised with the regulations in other European countries and the international IEC standard. However, there are a number of specific national practices, habits and traditions that differ significantly from other countries, and which in some cases survived harmonisation. These include the use of ring circuits for domestic and light commercial fixed wiring, fused plugs , and for circuits installed prior to harmonisation, historically unique wiring colours.
An electrical circuit is a continuous loop. Household circuits carry electricity from the main service panel, throughout the house, and back to the main service panel. Several switches, receptacles, light fixtures, or appliances may be connected to a single circuit. Current enters a circuit loop on hot wires and returns along neutral wires. These wires are color coded for easy identification. If a circuit carries too much current, it can overload.
