How do you check for a 240V electricity supply?

Answer 1

You should check for voltage with a meter or a test light. You should see 220V between both hots, 110V between either hot and neutral, 110V between either hot and ground, and 0V between neutral and ground.

Answer 2

By asking this question you are probably not quite ready to take on this particular task.

Really, don't do this one yourself. Electricity is far too dangerous to handle if you have not been trained how to do this work. If you use the wrong size and type of cable for the job and/or put just one wire in the wrong place, you risk being killed by electrocution or you could even start a house fire.

How to do this job depends entirely on the Wiring Codes or Regulations for the locality (Town/County/State) and on the exact location of the electrical equipment you wish to be installed. If situated anywhere that is subject to water splashes, water spray, dampness or humidity - such as in any room supplied with running water pipes, like a kitchen, laundry room, bathroom, shower room, etc., or in a workshop, or garage (or anywhere outside a building in the open air, such as along an outside wall - or a pool-side area) in many places nowadays it is actually illegal to attempt to do this kind of work unless you are already a licensed electrician.

If you get any other answer here, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or even their life.

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.

Answer 3

To check for a 240V electricity supply, you can use a digital multimeter set to the AC voltage mode. First, make sure the power is off, then connect the multimeter leads to the live and neutral terminals of the power outlet or electrical connection. Turn the power back on and read the voltage displayed on the multimeter to confirm if it is around 240V. Make sure to follow electrical safety precautions when working with electricity.
