Ballast Semi-Conductor Trouble

I had worked with some "Sassy®" ballasts that have a fuse., these don't ., but are failing and accumulating.

What needs be done to repair them ???

many different lighting arrays depend on these in commerce:

The Lighting is Basicly All Fluorescent Spec: lamp type 4/F32/t8 ~ 32w/.094 A line current/ ~temp @ 0°F.

NOTE: oddly the ones most (perhaps the only) failing are near heating ducts or other high temp. output sources.

OR: will we have to trash them too ? [they seem very simple to repair]

" if only " i (one) could put em in a microwave box oven and they'd come out working as new ;-) nano lessons...

" if only " I (meaning you) had them:

I can see that happening., but he must have shorted the line circuit to those fixtures., like when you accidentally short out the line from or to a dimmer, they are easily toasted too., i guess the mfgr is the best way to go., i'll check to see if they have a return or warrantee policy THANKS

ballast in the room.

I can't imagine why you would have a helper do this when the the outcome would be obvious...

More like voltage back-surge from transformers, maybe someone can help me here, been 15 yrs since school, been outta the trade, but if you abruptly cut current or voltage (which one exactly?) from a transformer, you get a resulting surge of current as the magnetic field around the transformers' conductors collapse and induce a back surge of current as result of cutting all those coil wires...

something like that, anyway...

I've Found the "Advance " =AE Company Return/Repair Warranttee page

I'll post it here later. Thanks you All.

About that question: it's best practice to disconnect the Hot or Current Carrying Wire First always, and when connectiing anything it's best practice to connect the Neutral or White Wire first., always have the neutral & or ground connected whitin a circuit that is live or about to be livened ..

as per your concern, the neutral or retrun wire would handle any discharging when disconnecting the Hot lead., when you disconnect the Neutral Lead first, if there is a shunt or discharge from disconnecting the Hot Lead it will most likely go through the equipment or yourself rather than the neutral ground path.

NOTE: a Discharge alone may not damage your equipment, a Shunt or a Short Circuit to earth will definetly cause semiconductor damage.

Thanks for the feedback,
