Why is a red colored wire in a 120 volt circuit and what does it do?

It is used as a hot wire.
<<>>
In a three conductor cable set the third wire colour is red. In home wiring a three wire cable is used in a couple of locations. If the circuit involves a three way switching circuit, the cable between the two light junction boxes is fed with a three wire cable. Check the internet for three way lighting connections. The other location a three wire cable is used is in split circuitry. Your kitchen counter receptacles use this method of wiring. The tie bar in the receptacle is removed on the hot (brass colour) side of the receptacle and the red wire is connected to the top brass screw and the black wire is then connected to the bottom brass screw of the receptacle. The white wire, as always, is connected to the silver coloured screw of the receptacle. Another example of using a three wire cable is to take two circuits from the distribution panel to two separate circuits on the other side of the house instead of running two, two wire circuits. The three wire cable is terminated in a junction box and two two wire circuits are feed from this junction box to the circuits that require power. The two two wire circuits will use the white wire of the three wire cable as a common neutral.

Can you wire a 120 volt ballast to a 347 volt circuit?
No, not a good idea. You have to use a 347 volt ballast.
Will GFCI work properly if 240 volt split into one 3 wire 120 volt circuit?
yes
What wire size needed for 120 volt 3000 watt load?
AWG # 10 wire on 30 amp circuit.
Can one leg of a 240 volt circuit be capped and the circuit breaker changed to make an existing 240 volt outlet into a 120 volt outlet?
Yes, you can always have heavier wire than code requires.
How do you wire a 120 volt gfci into a 240 volt three wire?
You can't. The 120 volt GFCI is probably just a 2-wire (hot, neutral and ground) You would have to run a new 3-wire (2 hots, neutral and ground). The two hots are how you get the 240 volts (120+120=240). Also you must make sure the wire is gauged properly. #10 wire for 30 amps, #12 wire for 20 amps, etc.

yes
What color is the hot wire in a 120 volt circuit?
In the US of A, it's supposed to be black.

Can you use 240 volts with a 120 volt supply?
Only if the cable going to your well pump is a three wire. The third wire could carry the neutral and you will have 120 volts from either 240 leg to the neutral.
Why do white wire mark 120v?
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
What is the Color of neutral wire in 120 volt circuit?
For wiring in the USA the Neutral conductor is required to be white or gray by the National Electrical Code.
If there are a red wire a black wire and a bare wire in a 120 volt supply wire which is the hot wire?
Where there is a red wire involved that usually indicates some type of special switching arrangement or more likely a 240 Volt circuit. In this case there will be 240 volts across the red and black and they will both be hot. Normally for 120 Volts the black is hot, the white is common and the bare wire is ground.
How many watts can 14-2 wire run?
14 AWG wire normally supplies 15 amps. Watts = Volts x Amps x Power Factor. Power Factor has a maximum value of one. If you have a 120 volt circuit that would be 15 x 120 = 1800 watts or 1.8 KW. For a 240 volt circuit 3.6 KW.
Can you wire a 347 volt ballast to a 120 volt fixture?
Yes, but it will not work.
