How do you connect a single phase motor to a three phase power supply in UK?

In: Home Electricity, Electrical Engineering, Electrical Wiring [Edit categories]

Answer:

Answer for countries in Europe and other world areas running a 50 Hz supply service.

UK household AC power mains voltage is now 230V (previously it was 240V) 50 Hz. From a 415 volt 3-phase incoming supply you will get this voltage between any ONE phase and the Neutral.

Between any two phases you will get 415V. DO NOT WIRE IT LIKE THIS!

So, if you wire the motor to any ONE phase (and ONLY ONE) and Neutral you'll get the correct voltage.

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.

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.

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
