So likely you have a 3 wire dryer cord and a 3 wire branch circuit. The dryer neutral is bonded to the dryer frame and the third wire of the dryer plug.

There were code exceptions for dryers and stoves that allowed timer motor circuits to use the neutral as a current carrier and frame ground.

To use the GFCI for the dryer you will be required to add an additional conductor (new 3 wire+ground cable) and separate the neutral to frame bond in the dryer and use a 4 wire dryer cord.

Likely you also have some GFCI single pole breakers and replaced ungrounded receptacles with grounded (another code exception) and they work OK. The dryer and stove are different as there is current on the third wire where as on the ungrounded receptacle GFCI there is no 3rd wire.

In breif, the neutral (current carrier conductor) from the dryer must be isolated from the dryer frame and dryer ground (fault current carrier conductor).

Or just leave it the way it was.

Check with local authority with jurisdiction for local code requirements.

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...

you may have agfi outlet in the circuit. the outlet has 2 push buttons in the middle. it maybe an outside outlet that is tripped some contractors hook up the circiut like that

Check garvin Industries website. they offer a multiple of different lock systems for breakers

Add up all the amps from active breakers. Do they add up over 200? If not, then I suspect a bad main breaker. If they do, then you need a larger service box and or main breaker.

possible. id call your electrician and let them troubleshoot it. high voltage should not be messed with.

A four wire service out to the fuse box would be required.

No. your panel is designed for full size circuit breakers. Check the label inside the panel and it will tell you what style circuit breakers are allowed.

It sounds like the breaker at the metering base is tripped. You will need to locate the meter base outside to find the breaker. You can also call your local utility company service provider and report a power outage. they typically will come out free of charge to verify power.

sounds like a loose connection ,or possibly a weak main breaker.

Yes it's correct the Ground Bar connects to the metal box, scrape some paint off to make a good bond, this also requires 4 wires to be correct, green ground, white insulated neutral, black L1 and red L2

3200 watts or 1600 watts on each terminal.
