You will have to check to make sure. Normally, with 4 wires, the black and red are both power for 220. White for neutral and bare for ground. If you are only using one leg of it, you would use the black, white, bare ones and cap the red one. Someone may have used the 4 strand because they had it or 220 was planned but not done or both the red and black are hot. You should be able to tell in the panel. Do the red and black both connect to separate breakers or to one or is the red not connected?

Can you change an old 30A fuse box if it has 1r1b1w wire to a 15A gfci for a whirlpool tub outlet?
Yes you can. It involves working in the breaker box and changing out breakers. You'll also have to "re-identify" the black wire to green for your ground. If you think you can do this, post back and I'll provide details on how. Yes I Can! The fuse box has 2 30amp fuses. At the breaker box you'll need a single 15amp breaker. YOU CANNOT USE THE EXISTING 30AMP BREAKER! Attach the black wire to the new breaker and the white wire to the neutral bus (where all the other whites are attached). You now have a red wire remaining. You'll use this as the ground wire. YOU MUST perform what is called "re-identifying" the wire by wrapping green tape around the wire. This lets someone know that the wire is a ground wire and not a hot wire (red is hot, green is ground). Attach this wire to the ground bus (where all the bare copper wires are). Wiring the GFCI is just like a standard receptacle (black and white on the terminals and your RED (which has now become a ground wire) on the green ground screw. Make sure to wrap the red wire with green tape at the GCFI also! This is very important!
How do you wire a 240V stove plug if old stove was hard wired and had 4 wires Black red white and ground coming from the wall are three wires Black red and a shield wire is the shield wire the neutral?

Why does a light turn when you place black to black and white to ground wire?
You don't say "turn off" or turn on". Light should be connected black to black and white to white and ground to ground. If you connect white to ground it will work, but you are then using the ground wire for an unintended purpose. Neutral is bonded to Ground at the panel. Current on ground wire could cause ground loops and may cause GFCI to trip if you have them in your house.
1979 ford f100 fuel tank theres a green wire and a black wire where does the black wire go the green wire is hooked up but not the black one?
One wire goes to the sending unit in the tank. It should hook to a terminal beside where the fuel line connects. The other one grounds out the body of the sending unit or the whole plate where the fuel line goes into the tank. 3-4 inch round plate. The ground wire will either go into the wire harness with the sending unit one or ground directly to the frame. The ground wire on all gas tanks very often rusts off.

If the fuse for the radio is good on a 2003 grand caravan what else would cause the radio not work?
If the fuse is good there may be a grounding issue. If the radio is an aftermarket one, try removing it and make sure that the antenna is hooked up and the ground wire (black) is correctly hooked up.
How many wires are connected to alternator on 1966 mustang which color goes where?
There should be three wires attached to back of the alternator of a 66. You should have a black wire with a red stripe hooked to the GRD post, a black wire with a yellow stripe hooked to the BAT post and a white wire hooked to the FLD post. The black wire with the red stripe is the ground and splits off with one end bolting to the engine block on the same bolt that holds the negative battery cable to the block, the black wire with the yellow stripe goes to the hot side of the starter solenoid, and the white wire goes over to the F post on the voltage regulator.
Power coming from 3 pin socket 240 volt then what should be the ground?
Power is coming from TWO of those pins. The third is the ground, or earth. Wires are color coded. In the US white and black are the power wires, green is ground, but this varies greatly in different places, and also with older wiring. DO NOT fool with this stuff if you do not know what you are about. Deadly.
There are only 3 phases that come into house main fuse box so where does ground and neutral come from?
It is very rare to have three-phase electricity coming into a residence. One of the wires is probably the neutral (It will be white or black with white stripes.) The ground comes in from a ground rod near the main, and connects to the ground coming from the meter, AND (If the main fuse box is the first disconnecting means,) the neutral and ground bars have to be bonded together in the box.

How do you extend the electric outlet at the basement?
Parallel connect the new receptacle to a receptacle in the existing circuit. Black (hot) existing to black (new), white existing to white (new), ground existing to ground (new). Make the ground wire coming into the new receptacle box longer so that it can be looped around the ground screw located in the receptacle box first and then connect to the receptacle without having a break in the wire.
