Power Issue...

[SpongeBob]

Testing my (250 MH x 3) + (160 VHO x 2) setup. I have two separate circuits set up just for the aquarium. When I turn off the lighting, my GFCI kicks off the circuit. I've tested on three circuits with the same result. Do I need to split up the load or does anyone know of other potential issues?

Thanks. :confused:

some MH ballasts will trip GFCIs. a function of them having caps and storing a charge.

you might need to run the lights on a non-GFCI circuit or try a different type of GFCI outlet or adapter. There are numerous types that will respond differently to ballasts and pumps (the two things that can cause GFCIs to trip)
