how do you connect a 3 prong cord to your electrical box?

Question

we need to have some simple electrical work done. A 220/240 hookup, 3 pronged outlet for a dryer cord, installed to the box downstairs. I have seen how most of it is done. However, do not know how to hook it up to the circuit box

Answer 1

WIRING INSTRUCTIONS; pick up the phone and call an electrician.

Answer 2

Any new installation of a 220 outlet is required by code to be a 4 wire. In a 4 wire you still have the two "hots" and ground and an additional neutral. The ground and neautral both connect to the same place in the breaker box. This presents a problem for someone with an older 3 prong cord on a dryer. You ncan either change the cord on the dryer, or install a 3 prong recepticle and connect the ground and leave the neutral disconnected. An electrician probably will not do this for you though. And I suggest against it. Replace the dryer cord.

Answer 3

If you already have the recepticle wired, then the three wires that come from that and end up at the circuit box should be one black, one white, and in the middle probably a bare wire, usually copper. Some wire made especially for 220/240 volts, will be black, red and white. One each of the black and red, if you have that configuration of wire, goes to each screw of a double breaker, which should be at least 30 amps for a dryer. The bare or white center wire should be connected to the neutral bar, where all the rest of the white wires are. That should give you 220 across each set of wires, black to white, red to white or black to bare, white to bare. Test the recepticle for proper voltage before connecting the dryer.

Answer 4

What are the colors of the wires coming from the plug? You should be using 10/3 min . 1 white, 1 bare, 1 black, 1 red. Red and black are hot ( 1 to each side of the 220 breaker). White and bare can be hooked up to the same bar if needed. If you only have 3 wires, white/black/green You replace the red with the white and tape the ends with black electrical tape. Your green is the neutral or return. Not the best way to do things.

Answer 5

Three wire connection to the power panel
Two wires are hot wires - each of those go to a dual circuit breaker capable of handling 30 or 50 amps (whichever is required. one wire goes to the ground bus along with the ground wire. The cable from the power panel to the dryer outlet should contain 4 wires.
If unsure please call a electrician. Cheaper than burning your house down.

Answer 6

Hey im an electrician.. the circuit box... do you mean the breaker panel? its easy, get the wire in the panel put the white (neutral) on the neutral and or ground bar, and then do the same with the ground. put the hots (power) on the breaker, and turn it on.
