those fuses sound like a gunshot when they pop! In my previous profession we had an account that would have us bring large portable generators out to locations for power outages. Sometimes I would pull up and just drop it and go. Sometimes, I would sit there for HOURS while they attempted to fix it. It was almost always in the middle of the night, so I would always take one of the trucks with a sleeper so I could at least be getting paid to sleep. They would often go to put a new fuse in, it would blow instantly, wake me up. Then try the fix, and blow another fuse, waking me up again. Over and over.
My parents were able to predict when that they were going to lose power. Whenever they saw a squirrel on the top wire, they knew it was going to "step off" right onto the transformer. Then out go the lights.
Oh yeah. We've had fried squirrel here a few times. Power company puts a plastic cage around the hot side of the transformer now
