An electrical wiring is an insulated conductor used to distribute power in any structures that needs electricity. Every state has established a national regulation for electrical wiring safety to protect life and property. Every country has also mandated a standard color coding for wires used for any electrician to follow it may be for flexible wires or fixed wires. Flexible wires example is the extension wires, fix wires are wires fixed at the back of the wall these are the wires that carries the power all over the building.
The capacity of the wiring to be use in a building depends on how much power it would need from residential to a high voltage establishment. A wiring system of a single residential unit is simple and needs low power requirements. While the high voltage structures are complicated and needs higher power requirement. The wire or cable is rated depending on the amount of current it will carry. It is also rated depending on where it will be use it may be for indoor and outdoor wiring needs.
