I don’t know to start this so here goes. I’m new to the group, the topic I want to bring up already is posted.
I bought a second hand compressor with no lead attached to the pressure switch. It’s already wired from the switch to the motor, the motor is 3 phase 3.0kW star connected.
The pressure switch is a Condor mdr3 skr3/6.3.
I have a 3 phase power outlet, that I use for my 7.5kW lathe, that I want to use.
I had a go at putting a 3 phase cable onto the switch but the motor rotated 1 deg and that’s it until the switch tripped out.
After doing a bit of reading and tube watching, I cannot understand what you do with the neutral on this switch.
Can someone point me in the right direction.
I’m in Australia
