I bought a relatively new electric range(Stove) to replace our broken
one. The "new" KitchenAid stove pig-tail has four primes, while the
outlet on the wall has only three holes. What should I do?
I was thinking there is some kind of adapter that I can directly insert
it to the 3 holes outlet on the wall and on its back there are four
holes. But the Home Depot people said that they have never seen that
kind of adapter. I am very surprised for that.
I called KitchenAid service helping line. They told me to replace the
pig-tail. I bought a three primed pig-tail at Home Depot. But, I found
it is very, very hard to unscrew the original one. Now, I am thinking to
change the outlet on the wall to four holes outlet by myself. Is this OK?
Thank you very much.
Considering that you don't appear to understand the electrical safety issues
involved, I'd have to say, no, it's not OK. It is *not* sufficient simply to
replace the existing 3-hole receptacle with a new 4-hole receptacle. It is
also necessary to replace the cable feeding that receptacle with a cable
having four conductors (two hots, neutral, and ground). If you don't
understand why, you shouldn't even be thinking about attempting this yourself.

Can you see the writing on the cable that feeds your receptacle? If it
says 8-3 / wg (6-3 /wg?) and has a red, black and white wire in it
plus a bare ground you can replace the receptacle. Just be sure the
white and bare are on the bus in the panel.
It was common to pull a 4 wire cable to a 3 wire receptacle since the
strict reading of the code implies the 3d wire should be insulated (it
is a neutral, also used as a ground). The bare usually went to the box
or back strap of the receptacle and the white went to the
neutral/ground pin lug.
If any of this seems confusing seek a pro.
I really don't understant why it needs 4 wires. My science education
background tells me that one wire(ground wire) is connected to ground to
let the eletricity escape to ground instead of to my body(shock). Why
need the fourth one?
When I opened the back cover on my stove, I saw the fourth one(green
one) is connected to the stove metal skin and is connected to the third
screw (the white wire). Since the 3rd and 4th wires are already
connected on the back of the stove, what is the purpose to have the pig
tail with four primes?

Study a little "Mr Ohm" and get back to us. If there is current
flowing in that neutral it will develope voltage across it (E=IR)
That will be reflected on the case of the stove. That is why we don't
want current on grounding conductors.

240V requires 2 hot wires (each 120V of opposite phase). The others
are neutral (used for 120V loads such as an oven light), and ground.
That jumper should be removed when using a 4 wire cord (properly
connected of course). It's connected for a 3 wire cord.
Also, it's a good idea NOT to reply below someone's signature. good
newsreaders don't automatically quote things after the sig separator,
making replies to that difficult.
Good morning. Thank you all for your information.
I have replaced the 4 prone pig-tail with a 3 prone pig-tail already. It
only took me about 5 minutes. The screw which the original green
wire(4th wire) connects was left open and is not connected with any wire
now. The other 3 screws connect with the 3 wires properly.
Stove is working fine. Clock, light is working fine.
The electric person at Home Depot gave the advice above.
No, don't. Call an electrician before you hurt someone.
The neutral carries live current pretty much all day long. You want a
proper 4 wire setup, and you are obviously too ignorant (and stubborn,
and possibly stupid) to realize that you are making mistakes at every
First, the blade on a plug might be a "prong" which is something
sticking out. However, a "prone" is something laying down.
Second, leaving the green unconnected sounds unwise. That's the
safety connection. If I was going to leave one connection open, I'd
leave the white open. You now have an ungrounded appliance.
The HD guy may not have given you the best advice.
