Title: Marstran Power Transformer Wiring
Post by: plexi50 on February 01, 2014, 10:02:12 am

I am finishing up a Ceriatone JMP 50 watt kit. I am now installing the power transformer i got from Marstran. Im getting lost looking for the neutral. #2 brown is 120 volt A/C line. Where is the neutral? H?

I would say yes that H is the neutral.

Do a resistance/continuity test of H with 1, then 2, etc. That will confirm if their on the same wind.
