What type of transformer does the NEC require in all distribution circuits except those circuits assigned to autotransformers?
What will be an ideal response?
Double-wound transformers separate or insulate the high transmission voltages from the typical consumer voltages of 115/230/460. The NEC requires this type of transformer in all distribution circuits except those circuits assigned to autotransformers.
