Electrical installation

INTRODUCTIN:
Electrical wiring is an electrical installation of cabling and related devices such as switches, distribution fuse 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. The International Electrotechnical Commission(IEC) is attempting to harmonise wiring standards among st member of countries, but significant variations in design and installation requirements still valid.
Wiring codes of practice and regulations, is so vital to follow for your safety.
