How is a house light switch wired?

The white wire from the service panel is wired to one side of the light. The black wire is spliced to a black wire in a cable that runs to the switch. That cable’s white wire is also connected to the switch and runs back to and is connected to the light.

Can I wire lights and outlets on the same circuit?

Yes, you can. The average home uses an indoor distribution board that houses the breakers of the majority of circuits in the home. A circuit controlled by a 15A circuit breaker (which a lot of contractors use for general lighting) can also accommodate outlets.

Why does my light switch have 4 wires?

Since the switch cuts the power on and off, there will be a black wire coming into the switch and a black wire leaving. The whites are normally just connected together with a wire nut and the coppers are connected together with a wire nut or grounded to a metal junction box. So the new switch has four wires.

Red: Hot wire for switch legs and connecting to hardwired smoke detectors

Blue and Yellow: Hot wires pulled through conduit; blue is often used for three- or four-way switch applications,and yellow is for switch legs to control fans,lights,etc.

How to obtain a wiring diagram or schematic?

How to Draw Electrical Diagrams. Making wiring or electrical diagrams is easy with the proper templates and symbols: Start with a collection of electrical symbols appropriate for your diagram. Draw circuits represented by lines. Drag and drop symbols to the circuits and connect them. Use line hops if any lines need to cross.

What are the basics of electrical wiring?

Electrical wire and circuit breakers are designed to work in tandem with one another, and each must be of a proper corresponding size. For example, 14/2 gauge electrical wire is rated to a maximum of 15 amps and should not be used with any circuit breaker larger than 15 amps.12/2 gauge wiring is rated to a maximum of 20 amps.
