HELP !!! New Stove Wiring

Trying to install a new electric stove. The existing house wiring in the box for the old stove is colored White-Black-Blue.

The new stove is wired Black-Red-Green. What goes to what ?? Need help really fast. Wife needs to cook now !!

thanx

 

I'm sure the installation instructions will tell you which of the 3 wires are the "hot" wires. Your present "hot" wires will most likely be black and blue, with the white being then neutral.

 

Unless you are in Euope. Then the blue is the neutral. You are best to check the other end of the wires and see what is connected to the breaker or get a meter and check the voltage on the wires.

 

To add to the confusion, the old stove had a RED- Black-White and a bare wire crimped (connected) to the White wire of the old stove feeding through metal conduit.

This "bare wire" , I assume ground, was then connected to the juction box with a screw, while the continuation of the White was connected to the White in the juction box. This leads me to believe that WHITE is GROUND. Is that right ?? Is GROUND the same as NEUTRAL ?????????

The new stove only has Black-Red-Green. Remember, the House wires in the juction box are Black-White-Blue.

Logic would then lead me to assume that, Black goes to Black...Red goes to Blue....Green goes to White. and no need for a "bare" to the juction box.

I'm in California. What a PITA..... Why can't electrical guys get organized and keep their color codes straight and think about the next guy who has to follow their crappy work. How hard can it be ?? Kindergarten kids can teach them all about colors.

 

Well... neutral and ground are not really the same, but they are connected together in the main panel (unless it's a subpanel). But yes, white should be neutral in your situation. But I would not connect the white and ground wires at the stove or receptacle. There should be a neutral and ground bar in the panel, they should be connected there.

 

Where is this stove from? If the stove is European it may have trouble working on our systems. Green is ground in most of the world. What kind of stove is it, a rangetop? Does the stove have a nameplate on it telling what voltage it is? There are stoves out there that will run on 110v, just not common. I have never seen a stove that ran 220v without a neutral although it is possible. See if you can find out more information on the stove and post back then maybe we can help you better.

 

THe stove is a brand new Whirlpool glass cooktop 2002 Model rcc3024xbb. It's replacing an older Corning glass cooktop. It's 220 V with a 30 amp breaker at the Panel. So was the old one. No info on their Web site. No help at all.

The old stove had 4 wires. its White and Bare wire were crimped together and then Nipled to the WHITE in the junction box with a pig tail for the continuation of the bare wire then connected to the screw on the juction box (grounded). So that looks like the the bare and the white can be attached together and acts as ground and neutral at the same time. I don't understand this part. The other 2 wires were Black and Red. Black went to Black, and Red went to Blue in the juction box.

The schematic on the new stove shows L1 (black)and L2 (red) coming into the stove with Ground (Green) bing attached to the burner box on the stove but it doesn't show where the other end goes to. i.e., to a White or Neutral or juction box ground. I tried to post a pic of the schem. but no luck.

What would happen if I connected the Black from the stove to the Black in the Junction box....the Red from the stove to the Blue in the junction box.....the Green from the stove to the ground screw on the junction box....and capped off the White in the junction box and not use it ?????
HELP !!!

I'm in California USA. No European stuff !!!!

 

Remove the cover from the service-panel and look for a 30 amp. 2-pole breaker with Black and Blue wires connected to the breaker. This indicates a 220 volt circuit which connects to the Red & Black appliance leads.If the White wire is connected to the Neutral terminal bar you can use this wire for the Equiptment Grounding conductor which connects to the Green appliance lead.If possible, identify this wire as such with Green marking-tape.Ground the metal splice-box with a "jumper" from the box metal to the Grounding connection.-----Good Luck!!!!

 

Thanks PATBAA...It's starting to make some sense now.

That's what they did on the old stove. They hooked the bare wire and the white wire togeter, then ,from there, "jumped" the bare wire to the metal box. In essance, using the bare wire-white wire-metal box as ground AND neutral. How odd.....

I'll remove the panel and see what it looks like just to make sure. Stand by.

Just as you said PATBAA. White wire goes to the Neutral Bar in the panel. Black and Blue go to the poles on the 30 Amp breaker.

Turns out that this White wire is composed of a bunch of thin wires and one 15-18 GAU bare wire going down the center of it and then of course, to the Neutral bar. Looks like in total, its a 10 gau. wire rated @ 600V.

Apparently, this stove itself, has no bare wire and uses the Green for the Ground along with the White(Neutral) inside the stove circutry somewhere.

Well, hooked it up. Green to White with a jumper to the metal juction box, - Black to Black- Red to Blue. No ARCs, No Sparks, No Fires !!! And the stove works !!

Thanks to all for the help. My wife can cook again !!! No more gas Bar-B-Q.
