3 phase power from 5 wire to 4 wire
 
i recently purchased a commercial dishwasher that requires three phase power. I have a 4 pin point near the machine 3ph and earth (no neutral). The machine has five wires hanging out of it, 3ph, neatral and earth. how do i wire this up without the neutral?

I would imagine you do not. :no:

In the US you would have to run a new circuit; or in the extremely rare case of a full conduit run, pull a neutral in.

Are you sure it's 3ph and not 1ph 220 with neutral and ground (also 4 pins?)

Single phase may be required for solenoids, timers etc!

If so, you'll require a neutral. No easy way out of it!

OP stated machine has 5 wires. That would mean 3 phase plus neutral plus ground.

Normally in the UK system the voltage are 230 L-N and 400~415v L-L { both single and three phase }

You should double check the nameplate to see what voltage it required and It will be wise go get the electrician come in and have it termated proeprly due the L-L voltage may knock ya out.

Merci,Marc

I meant the outlet, not the machine.
