Re: [TCML] pig Jacobs
Hi Dave,
Yes, this will work but "I" would prefer to do my ballasting
via an inductor to do away with the resistive heat losses. An
old "Buzzbox" welder or a 500 ft. spool of #12 or #10 build-
ing wire would work pretty nicely. Of course now that winter
is just about upon us, you could conveniently heat your shop while
playing with your JL ;^) Just make sure that your resistor can handle
dissipating some 19 kW of heating without melting down! I'm
sure that it would have to quickly reach incandescence unless it
was something like 10 ft. long and may very well require forced-
air cooling to prevent meltdown! Resistance probably does go
up a bit with the heating but not still enough to negate the fact that
you will be wasting multiple kW of energy as heat.

Subject: [TCML] pig Jacobs
any problems running a 10kva pig through 3 ohms of resistance for a jacobs
ladder ?
Im on a 50amp breaker , it didnt trip,.., my clamp on amp meter is broke
:-(
3 ohms @240 v would be like 80 amps !? , but, resistance goes up
with temp ?
Thanks, dave ( one Helluva flame commin' off that LiL'
pig ! )
