I’m upgrading to a 200 amp panel and I’m using a surface mount on my stucco exterior. I tried reaching my inspector but due to the pandemic he’s been unavailable.
I will be applying urethane caulk around the top and sides of the box.
What is proper practice for running (nm-b) cable from the inside of the wall into the knockouts of my exterior main panel?
My electrician says to the caulk is enough, I just want a second opinion.
