Siemens Electrical Supplies - Recent Questions, Troubleshooting & Support
My company wired a residence Inn Hotel and we had
The only way to really see what's going on is with a scope to look at the wave form. The arc fault breaker is the latest attempt by the NEC to control the world. Let's get real here, why on earth would we need 'arc fault protection'? The circuitry is 'looking' for a arc on the load that would indicate a potential ground fault or short circuit.
I've heard nothing but negative problems associated with these devices. Too bad they are now required by the NEC. I wonder who got that 'pushed' through'...? There probably making bank right now.
Sorry to voice my opinion, let me get back to the problem at hand. I really doubt it's the Chinese ballasts. It's probably more to do with the voltage level with no load, compared to the loaded voltage level. Also, it could have to do with the 'Harmonic Distortion' created by a large 'lagging power factor' coming from the ballast load. A small filter at the service entrance would probably eliminate your problems, but it's really not your problem is it? The building owner would be the one that has to mitigate 'his' electrical system issues.
A good engineer capable of doing a 'power study' could have the answers for you...
