I'm hooking up a three wire (black, red & ground) cook top to a four wire (black, red, white & bare ground) house connection. How do I hook up? Thanks!!

Hello,

I suspect on teh wiring from the house the black&white will be the hot wires and the bare will be ground/neutral

use a volt meter before connecting tonew cooktop and check for;
black/bare to have 120volts
white/bare to have 120volts

if that is what you find...connect new cooktop as such;

black to black
red to (house) white

(cooktop) white and green to bare

each colored wire is for a seperate burner, the white wire connects to the white neutral wire the bare wire connects to the ground the red and yellow wires connect to the red wire (L1) and the black and blue wires connect to the black wire (L2). i have the same model and i connected mine this way and it's working fine. mine is also connected in a box that has a seperate fuze for each burner so you can follow the red (L1) wires to the 2 fuzes and connect your red and yellow wires to these fuzes and the follow the black (L2) wire to it's 2 fuzes and connect your black and blue wires to these fuzes. i don't know if this box is necessary or ir you can just connect directly to the wiresin a regular box and rely on the breaker but it was already there from the old cooktop i replaced so i used it. hope this helps you

It sounds like you better be careful for starters. I also suggest your handyman sticks to painting. In older homes a 208/240 circuit onlt had three wires. New construction and remodeling requires a four wire system. Per code, a black wire is 120VAC, and a red wire is 120VAC. In a 240VAC circuit they would be called L-1 and L-2 respectively. In order to provide 240VAC they must be on seperate phases. The bare wire in your bundle is the ground wire and is at the same potential as neutral, or the white wire in current four wire systems. If you know how to use an electrical test meter, you should show 120VAC from black to bare copper, 120VAC from red to bare copper, and 240VAC from black to red. If this is not the case, I strongly suggest you have an electrician come in and take care of it in your breaker panel. *****Electricity is nothing to fool around with if you are not absolutely sure you know what you are doing. A loose connection, a wrong connection can result in fire, serious injury or death. It's worth a service call to a licensed electrician or qualified appliance service technician to give you peace of mind, and years of safe use of your new cooktop.

depending on your local electrical code:and I see that the unit is 240 Volts A.C., then RED=Power/Black=POWER(L1 & L2)/WHITE="N"Neutral/and GREEN=SAFETY GROUND,on the new unit, then use from the wall power BLACK = L1 and White= L2. then on the unit RED=L1 and BLACK=L2(either way you hook these 2 up there isn't a polarity issue on these 2 wires) on the units hook-up/then use the BARE supply wire as neutral and tie BOTH WHITE and GREEN from the unit together to this BARE wire

This is not to code. The white is neutral and is of the same polarity as a bare wire. The red and the black are considered hot and would be 220.

sound like you have a three wire setup on you house most commonly the black wire is the L1 wire or one of the hot wires and the red is the L2 wire and is also one of the hot wire in this instance your white wire would be your neutral/ground wire this would connect to the copper wire on your cook top depending on the model it would have a red wire a black wire and the copper wire but some may also have a white wire also if this is the case on a three wire setup you would attach the copper and white wires together also if needed you can goto the maufactures website and download an instalation guide.

Older 3 wire connectors where Wht=Neutral Ground Return, Red=One Phase Hot, Blk=Second Phase Hot, of 220VAC stove connections.

Newer Electrical code standard has a forth wire that is bare copper for a separate safety ground return.
I suggest you but a 4 wire pig tail cable for your stove top, available at Depot or Lowes, and connect 3 wires of this 4 wire cable just like the 3 wires are now connected. The 4th bare copper safety is attached to any metal part of the stove. Find a screw you can loosen to wrap it around and tighten.

Cook top manuals and installation.

Could not find installation manual on oven but did find manual. If you are just trying to wire to the house wiring you need to conect this way. Yo uwill have 3- 4 wires from the house. 1 white, 2 black or 1 black and 1 red. From range hook white to white Black to black or red they both are the hot line. and the other black or red to black or red from the house. If you have bare wires that is the ground There is 2 ways to do the hook up on the ground. 1st way is if you have ground in box from house wire them together. 2nd way is if there is no groung just wire it up with the white wire that is the netural line. It will be fine that way. If you can see in you main braker box the netural and the ground go to the same bus bar.

Good Luck and If you have any more ? fill free to ask befor you rate.

those wires dont go to the down draft. those colors are to hook up the stove. do you have the instalation instructions?

usually black(120v) white (n) and red(120v) bare wire to ground, but if htat what yo got and your sure of incoming voltage, blabk to black , red to red, and white to white is normal..co loang as you 2 power legs are hooked to either power line, the bare goes to the nuetral/ground. thikn i mighta confused myself here, but theres no other way to wire it
