CE4000 Pops GFCI

5 posts in this topic

Hello. I have a CE4000 that is out of warranty, that when I plug into a GFCI outlet it trips the GFCI. When I do outside gigs I kept having this problem, and traced it down to this amp. I am guessing it is leaking power somewhere and not returning all the current back to the neutral, then because of this tripping the GFCI outlet. Has anyone else had this issue? How could I go about trying to find the problem? The amplifier itself works fine on any regular outlet.

Thanks.

Is it a fairly long run to the GFCI? I bet you've got some RF leaving the amp and the GFCI thinks its an AC fault.

I would look at using a motor start breaker for amplifiers. All amplifiers have a bit of in-rush current as they are starting up. Most of the common off the shelf Ground Fault Breakers see this sudden rush of current as a ground fault and will trip.

This is not true.

GFCI only trip on an inbalance of Line hot versus Line neutral current.

If large start currents tripped them, every hair dryer and air compressor (Bathroom and Garage, both now required) would trip them.

OK maybe I over simplified the statement. What I was trying to say was...it is possible the GFCI he is using is sensing the turn on rush of current and it is more than the GFCI wants to handle and is tripping. We have found that most GFCIs are more sensitive to sudden current rushes.

Besides that GFCI have been know to become faster acting as they are overly tripped.

Either way I would still recommend a motor start breaker.
