Hi

Good day Leon,

I hope you don't mind, i read your reply posted on CR4 and wondered if it was at all possible for you to request from you a copy of the Moeler Wiring Manual for motor control starters.

It will be much appreciated if you could oblige. I live in Cape Town and am in dire need of this information.

Thanking you in anticipation.
