I wanted to open this panel to inspect what I’m assuming is the main service disconnect but couldn’t get it open. I released the latch at the bottom and tried lifting and pulling the panel out but it seemed to be stuck somewhere at the top. It has hinges on the left side.
Any advice on trying to get this type of panel open safely?
About 5" down from the top and 1" from the back in photo #3. Funny looking slot with flat sides. Turn and hold while you depress the latch on the front and try to pull the cover open. Might need three hands.
