This is an important thing to factor when planning small facilities  
that may be in small office buildings or converted homes, where 15 amp  
wall circuits for lamps run to four or five plugs in a room and the  
circuit serves several rooms. It's easy to overload the line.

It's also the equivalent of a 1KW heater, which may help in some  
places during cold weather, but isn't much fun in the summer.
