Hi everyone

I purchased a bench polisher which looks to have come from China. It says its 220v single phase and should work fine in the UK. The power cable has 4 wires in it so I'm confused how to wire a standard UK plug. I have attached a photo of the cable.

Any advice would be much appreciated.

Looks like a forward and reverse switch is required. What do the manufacturers instructions say? Do you have a web link for this machine?
 
Welcome to the forum mate.
The motor should have a information plate on it, with the spec of the motor. Take a pic and post it up. Post a pic of the motor as well. Are there any controls with the motor?

Hi thanks for replying, ive attached images of the machine. The machine is a 220v machine and is supposed to be single phase. It didnt come with a plug, the power cable has 4 wires which is confusing me.
 
That's a surface grinder not a polisher so you won't be getting many shiny things from that...

You need a motor reverse switch installing. Something like: Motor Reversing Switch single or 3 phase 25, 32 or 63amp 4 Pole Lathe car lift | eBay - https://www.ebay.co.uk/itm/Motor-Reversing-Switch-single-or-3-phase-25-32-or-63amp-4-Pole-Lathe-car-lift/331117252512?hash=item4d18204fa0:m:mwsgmUcdOA3BgKppYa0rovQ&var=540332832124

Ideally you need someone experienced with motor controls to install this for you.

H Strima thanks again for replying, I was wondering does it really need a motor reverse switch as it has a FORWARD/REVERSE switch already at the front of the machine.

It seems to state the motor needs 380V. You will only get this if the machine has something like an inverter in it.

Can you take a pic of the plate on the motor.

This might give us more info.
 
Take some pics of what you actually have rather then from a brochure.
 
Just wondering if that motor is three phase, 380v in star and 220v in delta. Your motor maybe pre wired for 220v delta, possibly.
 
Looks like the only thing you can do is get inside the machine and see where the four wires wire to.
 
The motor doesn't show a capacitor but could be split phase (single phase) but I suspect it is three phase and there is no reason for it to be reversible. The image of the machine does show a two position switch so maybe reverse capability is built into it.
