Breaker tripping with LED s

[Stevenfyeager]

Have you had any problems with breakers tripping after LED fluorescent bulbs installed if that circuit shares a neutral with another circuit? An office lights circuit trips occassionally. Thank you.

And the breaker(s) in question are neither AFCI nor GFCI?

No

The immediate thing that comes to mind is that due to high inrush currents even a minor defect in the socket shell and its termination could cause excessive arcing which in turn creates a carbon trace (which can be conductive to the point of shorting) either on the bulb between the tip and shell or in the socket itself. Remove the bulbs and inspect for this, I have seen this before cause breakers to trip.

Might be a bad lamp. 1 of them could be having problems. Are they direct wired LED lamps or ballast driven?

Do they trip out mainly at switch on or switch off ?
Or during the day with no pattern to it ?

Sorry, I re-read that you must be talking about 4' LED tubes?
I was referring to bulb style but could see the same thing happening in your situation though, since I've seen some tombstones smoked due to high frequency energy causing the same carbon trace with those as well.

As Steve said, inrush to a likely cause. If you can split the lamps in to smaller groups give it a try.
