[TowerTalk] dump power?

[Al Williams]

I did a google search on "dump power" and got 149 hits including two of
Tom's towertalk posting.
Other hits ranged from John Deere's tractors to garbage dumps but at
least two others indicated that it is a common term used in power lines
and also integrated circuit power line layout.

I suspect that some other Towertalkians are like me and it is an
unfamiliar term.  We will appreciate an explanation?
