Electrical wiring in general refers to conductors used to carry electricity and their accessories. This article describes general aspects of electrical wiring as used to provide power in or to buildings and structures, commonly referred to as building wiring. Electrical wiring practices vary greatly by locality. This article provides general information that should apply worldwide.
On or Off The Grid

Electrical wiring may be "on the grid", meaning that it is continuous with common electrical utility supplies. In North America, this means alternating current (AC) at 60 Hz, with 120 volts nominal. In European countries, this means AC at 50 Hz with 230 volts nominal.
"Off the grid" electrical wiring is often configured to carry direct current (DC). DC systems often run at a lower voltage than AC systems and so heavier wiring may be needed. This however is often offset by the fact that off grid systems are usually configured to minimize electricity use.
