Red and black are the two separate 120V hot legs of a 240V 60Hz supply, green is the ground. White is the neutral. (US color coding.) === === === === === === === === Red is the 230V 50Hz hot, black is the neutral, green is the earth or ground.

Note: Those colours became obsolete for use in the UK for all new wiring installations done since 2006. The new colours are: Brown is the 230V hot, blue is the neutral, green/yellow is the earth or ground.

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS.

If you do this work yourself, always turn off the power

at the breaker box/fuse panel BEFORE you attempt to do any work AND

always use an electrician's test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized.

How do you wire a cook top 240V 3 wire black green white to 240V 4 wire service?

Black would be hot, white would be hot, and green would be common. Four wire is usually two hots, a common and a chasis ground. Just make sure you don't connect one of the service hot wires to the green wire. So, if you are wiring this to service with black, red, white, and green (bare) wires, you connect black to black, and green to green. The white wire of the cooktop connects to the red wire. The white wire of the feed should be capped with a wire nut.
