How many watts can a normal household circuit handle?

[trilinearmipmap]

I am in the planning stages. When I look at 2 x 250 Watts of MH lighting, plus ~220W of VHO, plus ~250W of heater, plus a pump, plus powerheads, plus Ca reactor pump, plus refugium lighting, plus skimmer pump, it adds up to something like 2000 Watts.

Can a normal household circuit handle this? I need to know ahead of time, I don't want to buy all my equipment and then find it blows my circuit breaker.
