Can you or staff help with this question?
I came across generator interlocks on an a Seimens electrical panel as shown in photo. They are intended to force main breaker shut off to stop back feed when the generator was on.
The problem was I could not get the panel cover off. I tried turning off the main beaker and sliding the sheet metal but the smaller breakers sheet metal guard still interfered with the cover removal . I removed all visible screws on the sheet metal and the guards still seemed fasten tightly.
Is there a way to safely remove the cover to inspect inside? . I don’t want main or large breakers popping off as I wrestle with the cover.!
