Hello,

If you are going to go this route, I would put a full 500' roll of #10 on
both legs of the 240v do not connect the center neutral. The case is
grounded generally to the RF ground. Caution, the pig will silently wait to
kill you, there is no second chance. Read all the posts. There are a great
many. Also, you didn't post the pig's ratings.

This is what i used as a ballast: A 500ft spool of multi stranded 12AWG
INSULATED wire.  It limits me down and, i have never triped a 20A breaker
yet..not even close to come to tripping it.

You just take the spool, take out both leads, strip them and put it on the
HOT side on the primary out of the wall.

Hi Tyler,

A resistive ballast is less efficient, because it actually dissipates
power in the form of heat.  An inductive ballast does not actually
dissipate any power.  However, a resistive ballast is generally easier
to build.  Many people have used water-cooled heating elements or large
saltwater resistors as resistive ballasts.  An inductive ballast for
something like a pole pig usually requires tight winding of relatively
large wire around a large core.  If power is plentiful, and you don't
plan on operating near your maximum available power, a resistive ballast
should do fine.  Something else you may consider is a high voltage
capacitive ballast.  I've used this successfully with MOTs but I'm not
sure about the implications with pigs.

(Note: I've never used pole pigs myself, but I've read a lot about them,
and I have ballasted MOTs)

Chris
