Can I add a main breaker to my panel?
The panel itself can come with a shutoff breaker, however at the size you will want to install (larger than your current plans for sure) it will be oversized. That is fine as long as the feed wire is protected at the main panel with a 50A breaker. Other wise you can backfeed a breaker.
How do you install a main breaker in an electrical panel?
Quote from the video:
Quote from Youtube video: So what i'm going to do is clip it into place. And all you got to do is line up these little notches. With this little notch here on this plastic bar and then just slides over these two prongs.
What if my panel doesn’t have a main breaker?
Since your panel does not appear to have a main breaker, you would need to call your power company and have them come out and pull the meter. They need to do that anyway to investigate the lost neutral. Now might be a good time to get a meter pan which contains a main breaker.
