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.
