Hello Michael,

Sure!

First, check out my page here: pressure switch models and options.

If you scroll down, you see a picture of the wiring. This is for a single phase compressor/pressure switch. For a three-page pressure switchs, it is basically the same, only you have 3 pairs of contacts.

The 3 wires from the motor are connected to the bottom 3 connections. The 3 incoming mains wires are connected to the top 3 connections.

Also see this information on the Condor website.

Hope this helps! Let me know if you need more information!

Good luck.

Cas.
