Any service entrance cable that comes from a meter going into the homes main electrical panel should be evaluated at least every year after 15 years. The sun’s UV rays will deteriorate the cables exterior insulation to the point it completely crumbles away. But long before that it will allow for rain water to follow the path of the cables in to the main electrical panel where it often oxidizes and rust many of the panels internal parts including breakers often to the point it all needs to be replaced. So don’t let it get that bad before you catch it.

So just to sum that up, it’s a 3 phase electrical panel, that is a fed with a 3 wire SEU cable.
“A” phase is 240 volt to ground, “B” phase is a bare wire that is bonded to the cold water pipe and the panel can but then goes to the B phase spot on the main breaker for the panel, “C” phase is 240 volt to ground and when going from A to C phase it is still just 240 volts.
B phase to ground is zero because there is no difference of potential.

This system did run a 480 volt 3 phase welder too( of course after verifying with the welder manufacturer)

I do know what’s this system is called now but just for fun let’s see what you guys think!

I bet your not gonna guess the who makes this breaker in my hand. Answer in the comments below and then swap over to the see the answer.

In the next pics let’s have a caption that says. I was blown away to see a non SQ D QO breaker in a QO panel, while I have seen knock off breakers before I have never seen one made by a big name like Siemens.

Trick of the day, when cutting big conduit it can be hard to keep your cuts straight. Well the best thing to do to prevent that is to give yourself a line to cut on and here are two ways to easily give your self that cutting line. First is to use a piece string or wire to wrap around the conduit tight giving yourself a tracing edge. The second option is to use a tape measure itself. Happy Cutting!
