I worked for a telephone company in SO CA in the western Mojave Desert, in or near 1984 or maybe the next year 1985 in late June or early July, I had pulled into our central office yard around lunch time and heard a loud popping sound as I walked towards the side door of the building where my office was, our standby generator started at the same time and I look up where I heard the noises coming from and saw a bunch of sparks shooting out of the fuses on the power transformer going to the feed wires to our building, it popped a bunch of times sounding just like a 12 gauge shotgun going off and each time it pop it threw out a lot of spark that looked exactly like exploding silver fireworks on the 4 of July but it was bright sunshine day in the desert. It turned out we had upgraded and added enough additional equipment in that office due to a lot of growth in that service area and we had overloaded that transformer which ended up blowing out those fuses.
The power company came out right away and replace the transformer with a larger one and double the feed wires to our office, no more problems after that
Luckily none of the sparks cause any ground fires or set the pole and transformer on fire, that is one of those experiences you never forget.
Electricity kills people every year, be careful working around it please.
