I just found a good diagram that shows the wiring on the T103 It says the nuetral gets hooked to A to run the clock on 240 and on 120 it shows the nuetral coming in to terminal a then carried out to load. I think Im way over thinking it. Im going to try the 103 on 120 first then if itwont work that way I can always hook it 240 .
The T-103 has double-pole contacts, so it is suitable for switching 120v (using only one contact) or 240v (using both contacts). The clock motor is 120v and must always be hooked up to 120v ONLY. In the case of switching a 120v load, the neutral would be paralleled between the load center, the clock motor and the downstream load. The clock motor can be driven with one leg of the 240v feed, or the 120v feed, but the neutral has to connect to the other clock motor lead.
