How many prongs should I use for a 240V dryer?
I am going to make an assumption that it is a 240 V dryer. The prongs should be the two prongs for 240 V, one prong for the neutral center tap and one prong for ground. The safest is to change the old house socket to 4 prong and connect the ground socket to a real ground. Next choice would be to a metal water pipe. And if you really wanted to cheat, [not recommended and not to code] is to connect neutral house wire to both the neutral and ground sockets.
What type of cord do I need for a dryer?
The cord you have is a standard 120 volt cord, with the white wire as neutral and the green wire as ground.

I have a 3 prong cord with a green, a white, and a black wire.
What receptacles are used for 240V?
You will no doubt observe that this NEMA 6–30R receptacle will mate with the NEMA 6–30P plug on your existing dryer, and will result in the (white) neutral conductor associated with your existing 4-wire, NEMA 14–30R receptacle (that isn’t used or required with your 240V-only dryer) being wire-nutted and taped inside the receptacle junction box. This is because all that’s needed for your 240V-only dryer are two hots (red and black) and the (green) equipment grounding conductor. Hang onto the removed NEMA 14–30R receptacle for future use.
How many positive wires are in a 220V outlet?
That is a 220V AC outlet. It will have 2 positive wires that are each 120VAC that are 180 degrees out of phase. Likewise your electrical panel will have center tapped 220VAC available, and 2-pole breakers are designed to pickup the two hot leads of opposite phase.
How many wires are needed for a 220V outlet?
That is a 220V AC outlet. It will have 2 positive wires that are each 120VAC that are 180 degrees out of phase. Likewise your electrical panel will have center tapped 220VAC available, and 2-pole breakers are designed to pickup the two hot leads of opposite phase. The line to line voltage across the two wires is 220 VAC and the line to ground voltage for each of the wires is 120VAC. Ground and Neutral are the other two outlet wires. You might be able to get away with tying ground and neutral together in the outlet for your third wire lead.
How many wires are in a 240V water heater?
