My electric feed in has three sets of whires, one two red whires intertwined the other, two black entertwined with eachother, and the grownd whire. my cook top has a red, black, yellow, and blue, plus the ground.what color goes with what ?

hook color to color and then tie the white and grounds together. should be fine

Yes, Red and Black are supposed to be your Load wires (110) each then green for ground which should be white..Before I wire it up use a tester and make sure that is what is going on.

Since you have a red wire you must have 10-3 romex. 10-3 has four wires. Three jacketed wires Red, Black, White and a bare copper wire. The is Red and Black are your two 120 legs (both hot) white is neutral and the bare is ground.

You will need three phase for this appliance to work.

always unplug electricity before attempting to repair on any electrical appliance

if it's like mine white to neutral, bare to ground, red and yellow to the red, black and blue to the black

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.

the new cooktops and ovens now have a 4th wire used for separating the ground and neutral. some new homes and remodeled homes have a 4th wire run from the circuit panel to the unit.
you dont have this but it is ok to just hook up the white and green/ground wires together. then red to red and black to black. it will work properly and thats all you have to do.

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

Follow the wire, It should go to a junction box within 4 feet. It may be behind a cabinet. Remove the box cover and unscrew the wire nuts. It usually uses armored wire and this is clamped to the box. Release the clamp . Turn off breaker or remove the 2 fuses first.

To complying with changed Codes (effective in 2002 ) regarding stoves, ovens and dryers. You will need a 120/240 volt 4 wire 40 amp and 50 amp circuit. This
Decades ago it was permitted to use a 3 wire system (having two 120 volt hots (Black and Red) and 1 combination ground/neutral wire) (green and white) to serve stoves, cooktops, ovens and dryers.
The Code change now requires all stoves and dryers in NEW construction to have the 4 wire set-up (now having two 120 volt hots, 1 white neutral and one green or bare wire ground).
Existing wiring is grand-fathered under the Code change.....I advise you to change the feed wiring over to the the 4 wire set-up...
because - as with ALL Code changes in the past...it will eventually become mandatory for all stoves, ovens and dryers as the grand-father clause drops off. By complying now...
BUT the wiring will need to change to 8/3 with ground. (having 4 wires inside one outer jacket).This is the primary reason for the Code change....to provide a greater margin of safety to the user.
I can NOT recommend the 3 wire hook-up...the 4 wire provides a seperate ground and neutral -
which makes the chance of a user shock when touching the metal frame (from an internal fault in the oven) much less likely then the old 3 wire set-up....
which did NOT have the seperate ground and neutral.
