So last night when the power went out at my rental property, there were three transformers on the pole and 3 fuses. One of the fuses was blown and half the electricity was out at the property. I'm guessing that what this means is that while the house could have been receiving all its voltage from the transformer or line where the fuse blew, it wasn't. It was getting part of its voltage thru another transformer on the pole. Whereas on our block all the houses are fed off one transformer. Is there a reason to feed houses off one transformer or is it normal to feed houses of more than one transformer?
