Why are there 2 black and 2 white wires in ceiling box?
When you see two cables entering, and both blacks are already tied together, and both whites are tied together, that circuit is carrying current onward to some other point-of-use.
Why do I have 2 black and 2 white wires?
the black and white wires from the power supply side need to be attached to the line side of the new outlet. (it should say this on the back of the new outlet) and the other 2 are to be attached to the Load side of the outlet.
Why does my ceiling light have 5 wires?
It’s just a case of connecting the new light up in the same way the old light was wired. You may need an additional connector block for the wires that were connected to the centre ‘loop’ terminal of the old ceiling rose.

How long does it take to replace a light fixture? Most fixtures can be replaced in less than two hours. Modifications such as installing a different type of fixture, replacing a switch or rewiring may add an hour or more to the job.

What is the difference between yellow and white electrical wire?
For example, white sheathing means that the inner wires are 14-gauge and yellow sheathing indicates that they are 12-gauge. … The National Electrical Code (NEC) says that white or gray must be used for neutral conductors and that bare copper or green wires must be used as ground wires.
What does blue wire mean?

Why are there 2 live wires?
Connecting two live wires in such a way to the switch will do nothing if both live wires are from the same source, as no current will flow as they should both possess the same potential measured in volts ( An electrical current flows between points of different potentials) BUT if the ‘Live’ wires are from different …
What happens if a light fixture is not grounded?
The main issue is the likelihood of a user touching something metal on the fixture that could be accidentally live. If the fixture is out of reach, the lack of a ground is probably a low risk. If it is a pull chain light, use of a string pull rather than metal is a good idea.

This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair.
