Hello, I work on a ship with a floating ground, 480vac wye, no neutral.
I have installed LED illuminated push button and indication lamps on a switchboard, the source for the lamps is thru a transformer 480:120 Vac X1 is bonded to the switchboard.
The problem; the LED lamps are dimly lit when they should be off, I am trying to learn why the LED is lit, and how to properly solve the problem.
