My 2 cents: My home has a buried power cable from the late 60's. It's size can only handle up to 100 amps, my original main breaker was only 75 amp, we upgraded

My 2 cents: My home has a buried power cable from the late 60's. It's size can only handle up to 100 amps, my original main breaker was only 75 amp, we upgraded.(In my state all new houses have to have at least a 200 amp main.) The electrical trade is very rewarding, but very dangerous. You typically have to rely on co-workers to be responsible and safe, if they are distracted, life changing and/or ending results can occur. Before considering an electrical career, attend an arc-flash class to get an idea about what your are signing up for. If you are a detail person, it's a great trade. If you like working in all sorts of environments both in and outdoors, it's a great trade. It will take a long term toll on your body because of the mechanics of the jobs.
