Off-The-Shelf chokes



Original poster: "Cajun Coiler by way of Terry Fritz <twftesla-at-qwest-dot-net>" <cajuncoiler-at-cox-dot-net>

I recollect hearing of some personages using a
500 ft roll of #12 THHN as a current limiting
choke on their NST, and it was found to get warm.

I found such rolls of wire at the local Home
Depot for $18(and something) a roll, and so I 
begin to ponder...

Is there just that many amps being shot thru
the roll to cause the heat? Or is this just
normal dissipation?  Nobody mentioned if the
warmth was a "abnormally warm", or just an
average normal operation "warm".  Can we get
an official description of operation?
