with 220 ac power, I have 2 wires that are "hot" but they are both black. does the polarity "matter"?

Question

The wires on my new oven total 4. white, red, black and green.
The wires coming out of the wall are white, green, black, black.
As stated the only wires with current out of the wall are black, black.
I know that I should match up the oven black and red wires with these 2 black wires coming out of the wall, but does the polarity matter because of it being "AC" current?

Answer 1

If both are hot??? Then each SHOULD be 110 from separate circuits, I'd trace them from the panel to where your going to be sure, Green should be ground, White neutral, Chase them back to the panel to be sure.

Answer 2

It should not make much different. Both legs as it is called are both 120 volts ac. unless this is a three phase service. Then that will change the whole thing. One black wire to the black on the oven, the red wire to another black. White to the white. green to the ground of the oven. You should be fixed up. Good Luck. If not sure about the hook up some of your friend should know a person who can give you help through an electrician.

Answer 3

AC means that it alternates from a negative current to a positive current.

If you flip the wires, it probably does not matter, because the current will alternate from positive to negative for each of the wires.

The black and red wires on the oven are probably there in case the person is in a DC system. For example, if they are on their own personal DC generator instead of a cities AC power supply.

Answer 4

I would suggest contacting a licensed electrician first, to prevent any personal injury and to avoid damaging your oven.

AC [alternating current] means that the polarity alternates from positive to negative. You get your 60Hz if this reversal takes place 60 times per second. In your four wires you have two line [red and black] wires, one earth [green] wire and one neutral [white] wire. As long as you connect the two black wires from your supply to the black and red wires in your oven, you are ok. Connect green to green and white to white to complete the job.

Answer 5

No, it doesn't matter. when you are running 240 V. you can connect the blk to the blk or the red unless what your wiring is marked with the same color code. They just used two different hot colors to ID them. the pattern goes like this...green (ground) white (neutral) and two hot colors, IE... black, blue, red, yellow, brown. Advise..always connect your ground wires first, it's a good routine to get in to doing. Have fun getting wired, hope this helped.

Answer 6

didnt I answer this already? yes there IS polarity in 110 volt ac !
egads....and for 220 volts either red or blackcan be wired to the hots...with neutral being white and green ground..however on 110 outlets and plugs... they are polarized yes

Answer 7

DHWILSON has the skinny on the wireing, colors don't matter; they just tell you where the other end is plugged into so you can find it and ck it out.
blk & red in this case are the same, the whit is your common and the ground is green most always.
hook your blk to the blk and the remaining red to the other/remaining blk.
you'll do fine.
this is not rocket science.
JUST SHUT THE ELECTRIC OFF TO THAT RECPT.

Answer 8

egads sure there is polarity in ac....thats why for one hundred ten volt shops and cords you've a POLARIZED outlet or plug! although, with 220 volts it is variety of differant... having 2 hots, each and each and every warm can bypass to both red or black...with white being nuetral and eco-friendly floor...

Answer 9

polarity only matters on motors as long as you have 2 hots a neutral and a ground and right size breaker for a stove your fine

Answer 10

no, there is no "polarity" with single phase.

if it were three phase ( 3 hot wires), you would have to phase it out, but you are ok
