Good point!  Also (goes without saying??), *NEVER* put 2 or 3 (or more!)
of these babies on the same 110v circuit.  The fuser heaters are not on
continuously, they switch on and off to maintain the heating element at
temperature.  Everything will go along just fine until one day the random
event (all fuser heaters come on at once) will happen, and you'll wonder
what happened to the lights!  @:^)
