2 questions for an inspection I’m doing (see attached pictures)
how many branch service circuits can go through one knockout? There are about 4 in this panel.
When is it OK to have only 3 conductors (hot, hot, neutral) in a 120/240 main panel? This panel is on the inside wall while the meter is on the outside directly behind it. However, there is no ground conductor, and the ground and neutral bars aren’t bonded. The neutral bar has the green ground screw in it. Thoughts?
