[quote=Lawrence Duckworth;98650]In one of the photos of David Russellís transformer, I noticed what looks like a grounded leg. If thats what Iím really seeing there, can someone explain why that leg would be grounded?

One or the other leg of the transformer will be grounded to provide a ground reference, otherwise the system will function like an isolation transformer. Isolation transformers are not bad at all but if you do not ground diagnosing electrical problems is difficult because you have bo reference and all readings except the ones between the two transformer outs will be spurious.

Any electrical inspector except one who is familiar with flammable atmosphere wiring schemes (hospital operating rooms) will be very uncomfortable without it grounded.
