View Full Version : Magnetic Starter question??

02-26-2008, 10:28 AM
Hey all you sparkies! I finally got round to this mag starter.
Under the cover is a schematic. It shows the hookups for(straight through) L-1 and L-2. Cool!
But..this motor is only a 110V. The way it's wired right now...Neutral to L-2...jumper across to L-1.
Then the black (power) (Ooops Black power...is that racist?) wire goes to T-1.
(Whatever T-1 means?)
I'm betting this mag switch won't work correctly because the power isn't routed right to activate the magnets? There is no mention of 110V on the switch...only 220/440V.
So I'm also betting this switch never will work correctly with 110V???
So I'll be ordering a new 110V mag switch...right?

Your probably right. If you look on the side of the coil it should give the voltage it works at. If it is 120v you can use it.

The coil is internally wired to L1 and L2, so for 120v single phase you have to use L1 and L2 contactors. If you go back to your orginal thread about this problem there is a diagram of the starter relay for single phase use. You don't want jumpers across any of the contactors.

L1, L2, and L3 are the connections for the line voltage.

T1, T2 and T3 are the connections for the motor.

Thanks Carl (that was my Dads name BTW..lol!) I'll look see what the voltage is for the coil.
