Dubious.
From thinking about various homes I've lived in, I would guesstimate that the electrical panel could only support max 200 amps -- thats with every other item in home turned off, no fridge, no A/C, etc.
200 amps @ 120V = 24000 watts The average bitcoin miner uses 3500 watts (?), therefore thats like 7 miners.
Can 7 miners mine 1.5 BTC in 3 weeks?
