The "guts" of the 5 kva pig can be removed and mounted in a 13 x 13 x 14"
high 10 gauge steel box. We do this with our "pigs" as it makes them a lot
lighter to move around. Make the top out of 1/4 phenolic plate and bring
the 220 V and HV in and out thru this plate. Save the xmfr oil from the
tank and fill your box with this. We also leave a 5/8" lip all around the
top to attach a gasket seal and use a 10-24 machine screw every 2 inches to
attach the phenolic plate. This will allow some breathing without spilling
the oil unless you accidently tip it inverted. Runs great with a power
limiting reactor up to 15 kva if you keep the duty cycle short.
