Borehole pump wiring question

[Hanzcock]

I have recently pulled up the pump from a bore hole on some recently purchased land, the wiring had no plug on the end. There are 4 wires, green/yellow, black, brown and grey.

My initial thoughts were it must be three phase, but looking closely at the motor is says 220/230V.

Any idea how I wire this up, and to what type of plug?

It's single phase alright but you need a control box including a capacitor.

As above, you really want a control box. Phone whisper pumps, they will sort you out..

You need a 50 microFarad capacitor 450 volt rated (Y rated for continuous mains) between brown and grey, but if you are not up to speed on this you would be safest with an electrician to install for you.

If you don’t know if the pump works, then get it tested by an electrician first, before splashing out on a control box.
