The Basics of House Wiring
The basics of house wiring involve creating electrical circuits that provide alternating current to outlets, fixtures and appliances. The majority of household circuits utilize single phased power which can produce 120 or 240 volts of alternating current.
Single phased power utilizes two hot wires and one neutral. While the neutral wire is always used in connections, those made with only a single hot wire produce the lower voltages suitable for most small electrical devices and fixtures. Wiring both hot wires provides the higher output needed to power major household appliances.
The first step to a house wiring is to shut circuit power off at the panel. A non-contact voltage tester is used to guarantee that no current is flowing through the wires during installation. Basic house wiring begins with the main service panel which interrupts various electrical circuits that run throughout a house. Wiring a house requires the installation of a variety of different electrical circuits, including outlet, lighting, room, arc fault circuits, etc.
