thanks! 2 - 3pole contactors will work. Now, installing the time clock. There are 4 terminals, 2 line, 2 load. I'll parallel up the coils, but I don't see where I would need 2 wires in and 2 out for the time clock. I seem to remember there being a removable bridge in the time clock. Do I just remove this to have the 2 lines in so it acts like a switch for the contactors? But it must need power all the time to function, so ...... where does that come from? the contactors are the load side?
The feed phase wire from the supply would go to one of the Line terminals, the other Line terminal will be for the neutral, this will often have a link between the line and load side of the time switch, use a meter to confirm this though.
Connect your contactors to the Load side of the time switch.
Hope this helps.
