How do you connect a 3 wire 220v induction cooktop to a 4 wire supply?

Answer 1

Answer for USA, Canada and countries running a 60 Hz supply service.

A four blade range plug is the new code. What should be done is to change the three blade receptacle to a four blade receptacle. The only difference in the receptacle wiring is that the position of the neutral wire and the addition of a ground wire being brought out to the range on a separate blade to match the ground wire on the plug. Turn the circuit breaker that feeds the range to the off position. Opening up the receptacle you will find now, two hot wires to the outside blades and a neutral to the center pin. Look in the back of the range receptacle's junction box and you will see a ground wire wrapped around a screw that grounds the dryer feed wire. From this ground wire add an extension of six inches. This new wire then connects to the fourth terminal on the new four blade receptacle. Looking at the new receptacle you should have the two hot wires on the outside terminals X and Y, white (neutral) W blade and the newly installed ground wire to the U shaped ground G blade. This receptacle is a NEMA 14-50R, 3 pole 4 wire grounding receptacle.

Before you do any work yourself,

on electrical circuits, equipment or appliances

always use a test meter to ensure the circuit is, in fact, de-energized.

Answer 2

You will need to install a 4-prong receptacle and a 4-wire cable to connect the 3-wire 220V induction cooktop to the 4-wire power supply. The additional wire in the supply is for grounding, which is important for safety reasons. Make sure to follow the manufacturer's instructions and local electrical codes when making this connection.

Answer 3

Green or copper ground wire goes to the round connection on the plug or ground screw on stove. White neutral wire goes to the connection opposite of the ground or neutral on the stove. The red and black wires are connected to the other 2 connections or hot connections on the stove. Connect either one to either connection makes no difference.

Green or copper wire is ground

White is neutral

Red carries 120 volts

Black carries 120 volts

You would have to change one or the other so they are compatible.

You don't. In your situation the three wire range cable should be changed to a four wire. Instructions should come with the new cord. Open up the electrical access panel on the back of the range. You will see a terminal block with three wires going into it from the plug cord assembly. A red and black and white are now connected to the terminal strip. Look at the position and colours of the existing 3 prong cord and how it is connected. Make a diagram. Coloured wires on the outside terminals white in the center. From the center wire terminal you will see a jumper strap that goes to the frame of the range. When installing the new four prong plug this jumper is removed completely. The kit should have with it a grounding lug that connects to where the removed grounding strip attached to the frame of the range. This is the attachment point for the fourth green ground wire from the new range cord assembly.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
