Re: buying a pole pig

They do in 3-phase setups (never seen 208v single phase other than branching each phase into different breakers at the box). That's how they get 208v from a 7200-120 pig or 480v from a 7200-277.

Hi David,
 Do they ever hook the two HV
bushings on the pig between two of the Y three phase legs and drive it with 12470??? Seems like you could have the two LV windings in parallel and still get close to 240V and have each winding share in the 240 volt current.

Justin,

The "Y" refers to a wyed cross phase hookup in a
three phase configuration. 12,470 is the sq. rt. of 3
x 7200 volts. In single phase configuration, the 7200
volt rating is all that you will be getting and 7200 is
a little on the low side for a 15 kVA SG driven Tes-
la system, but hey, if it's free, then go for it.
