All of these transformers are rated at half there
peak current ratings.

For other KVA Ratings or Voltages:

                    KVA x 1000
        Amperes = --------------
                    Volts

15KVAs are the most commonly used transformer in Residental 
areas. Its best to run a 15KV on a 208-220 VAC circuit 
because of the Current ratings of most homes and business. 
This thing weighs about 300 pounds. Get a dolly cart with 
straps, you will need it.

Caution:
Becareful, some of these devices still contain PCB Oils. Most
of the PCB transformers have been replaced, but exceptions
still exist.

Oh, and don't forget, these transformers need ballast. Use
an ARC welder or variac attached in series to the 220 VAC.
And don't forget a circuit breaker.
