	If you set up the device, got it operating at 99%+ load, raised
the room temp to max, and then made accurate measurements of peak and
nominal current draw...  Well, it should come out about the same as what
the manufac rates the device as.


	If you install only enough to supply the devices at nominal load
you could have some fun, what happens if too many devices are powered on
at once?


	In other words, you are dealing with a pointy hair, feed em to the
paper shredder.
