lighting on gfci breaker issues

[mooreaaryan]

we are doing a control tower for branch of the military. they have asked us to put the lighting circuit on a gfci breaker. we complied and now the lights trip. the lights are led the load is a total of 11amp the gfci breaker is a 2oamp has anyone had problems putting lights on gfci breakers

New lights or old?
Are these inside or outside lights?

 

[hbiss]

I don't see why the load being lighting would have anything to do with it. If the breaker trips immediately check for a fault from neutral to ground. Beyond that, it may be possible that one or more drivers has some leakage to ground.

Process of elimination; see what you need to disconnect for it to remain set.

First I would check for things like pinched wires, but it could be the lights. How many lights are there? Do the lights have any L-G or N-G filter caps in their power supply?

Are we talking interior lights or things like the big rotating thing on the roof?

new lights new building entirely. The circuit has no issues when its on a standard breaker it only has an issue when gfci breaker is being used

internal lights, we re checked terms and found no issues but the breaker trip. we tried 1 light at a time and its still tripping my head feels like that rotating thing outside

The circuit has no issues when its on a standard breaker.

then Like Hal said you have a N-G connection somewhere or a driver leaking current.
you said you tried one light at a time did you disconnect all light and And see if it held. If it does just start at the first one and work from their.

Meg the circuit. Make sure you have no crossed neutrals. We had an LED fixture that would trip a LEVITON device, but would function quite well on a different brand.

Nearly 20 years ago, I had an issue with LV track lights tripping GFCI receptacles. Had to move the circuit to opposite phase from lights.

I’ve had issues with cheap drivers tripping gfi’s, changed to a different fixture manufacture, problem went away. Probably current leakage from poor board insulation.
