Am I overloading my power circuits?

[Agenesis]

So I got into this mining craze a few days ago and weird things has started happening. OTA TV is unwatchable, I figured it's some sort of EMI and bought an mohu jolt for it- fixed it completely.

Just yesterday two out of the total two of my ceiling light bulbs (the spiral ones) exploded and it smelled like plastic.

The two mining systems consumes 750w and 580w. I'm not sure precisely how many amps this particular circuit is rated for, but I assume the standard 15 amps.

Any ideas? What would cause two light bulbs to go out all at once? Would an overloaded circuit cause it?

An overloaded circuit could cause the voltage to sag and therefore make the inverters in a CFL work harder than they otherwise normally would. I would normally expect a breaker to go first though.

As for draw, all electrical circuits are derated to 80% by code, so you can really only draw 12A from a 15A circuit. Ignoring power factor for a moment, 12A * 110V = 1320W, so you're right on the cusp with your two systems.

Have you looked at your breaker box? Some old buildings have fuses instead of breakers. And sometimes people will put a penny or something in there to keep the electricity on if a fuse blows. That could allow the circuit to get overloaded more easily and cause the problems you're experiencing. This is very dangerous, and should be fixed immediately if it's the case.

I have a breaker box with breakers. Dunno about the OP though, he may very well have fuses.
