What Electrical Wiring Work Involves
Electrical wiring is the network of cables, connections and boxes that carries power from your breaker panel to outlets, switches, lights and appliances. Wiring work means adding to that network or changing part of it, such as running a new branch circuit, extending an existing circuit, or moving outlets and switches to new locations.
Every new connection is made inside a suitable box, such as a junction box or device box, so it stays protected and accessible. The cable is routed through walls, ceilings or floors, and each circuit is connected to a breaker in the panel that is sized for that circuit.
Good wiring work is mostly about planning. Before anything is installed, the electrician looks at where the power needs to go, what it will supply, how the cable can be routed, and whether the panel has room for another circuit.
