What color wires go together for a ceiling light?
Blue wire is for the light, if light is included with the fan. White wire is neutral. Green wire is for the ground. Red wire is sometimes included and acts as a conductor to carry power to the light kit.
Which color wires go together?
US AC power circuit wiring color codes The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active.
Can wiring a light switch wrong cause a fire?
An extension cord may be in use, for instance, or a wiring fault inside the wall. It is even possible, however unlikely, that there is a fault in the on/off switch which could cause a fire.
Can I change a light switch myself?
Replacing a light switch is a simple project. After you’ve turned the power off, all it takes is a screwdriver, a pair of pliers, and a few minutes. The first thing you need to do, however, is make sure you’ve got the right kind of switch.
What are the 3 wires in a light fixture?
A standard box for a light fixture will have three wires, a white (neutral), black (current), and copper (ground.)
What happens if you wire live and neutral wrong?
If your outlet’s polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing, but it is. There is always electricity flowing out of an outlet with reversed polarity, even if an appliance is supposed to be off.
How do you wire multiple lights to one switch?
You can do this light switch wiring in one of two ways. The most common is to daisy-chain the light fixtures by connecting them to each other and hooking the first one up to the switch. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a “home run” configuration.
Does a light fixture need to be grounded?
Yes, if you have a metal light fixture your fixture needs to be grounded. … It may be acceptable for the ground wire to attach to the fixture mounting hardware only, but if you have a metal light fixture you definitely want it directly grounded.
Why does my light switch have 2 black wires?

Why does my light switch have 3 wires?
A three-way switch is a handy convenience to control a light from two locations, such as at the top and bottom of a staircase. If the words On and Off aren’t embossed on the switch and it’s one of two switches that control a single light or receptacle, you have a three-way switch.
What happens if I wire light switch wrong?
You could put the switch on the neutral wire and everything would work, but it would leave voltage potential to ground in the light when it is switched off. That makes it a bit hazardous for changing light bulbs. If you became an electrical path to ground through a wet floor or something you could get a shock.
