Thanks Greg and Tesla. That's what I figured it had to be on the clamps. I always like to cover all my bases when going into a job. Most of the time I overdo it, but I'd rather over do than under do. As far as doing something out of my field, Electricity is my field. I do understand there is a lot I have not done, and I'm very careful to try and not get in over my head. Work is scarce and I cannot afford to turn down work if there is a possibility I can do it.
To Tesla: As far as cable is concerned for a drop, I HAVE NOT seen a 3 phase 200 amp copper feeder cable with a ground and neutral. Do they make such a thing? If so, looks like it would be so heavy it would not be feasible to hang from the ceiling. Be like fighting a giant Anaconda snake smile
Thanks for all the input.. Steve
