We have all seen those stainless steel (SS) electrical enclosures by traffic lights and outdoor lighting. Usually there is at least 1 or more pipes feeding into them. Now inside the pipe you have a 200 amp feeder enter and leave the SS enclosure, tap off a 60-100 amp line, go to a small 4-6 circuit panel.
Some questions,
1) Do you need a main on the small circuit panel?
2) Can you have open splice/tap or does that have to be enclosed in a box/through?
3) When the wires leave the feeder conduit, can they just run freely or be sleeved into a through where the tap will be made?
I hope I made myself clear, I have a friend ask me these questions.
