Are you using 120V 15A receptacles? You should never plug more than 1500W worth of anything into a single outlet, but you should be able to safely plug 1500W worth into a single outlet without creating a fire hazard.

Huh?
Why 1500 Watts? Why not 1800, why not 1440 Watts? Is this figure just pulled out of thin air?
