Mine has no such enclosure, just a door that takes no tools to open.

That might be a 1960s-70s-era Zinsco.

If so, you should get it replaced right away. Easy access to the internals is the least of your concerns -- these panels are unsafe as designed, and responsible for much fire and death.

Yikes! Did this pass an inspection like that? I'd highly suggest moving this higher up on the TODO list. Whether its a panel that needs replacing or just a cover needs to be replaced, it should be corrected. Please, don't become a statistic! </randoInternetNanny>

I have no idea when's the last time an inspector saw this place. It's a mobile home manufactured in the 60s so a lot of lax code is probably grandfathered in. The panel is too high and out of the way for a child to reach and I'm smart enough not to touch it. I imagine whoever I sell the house to is going to demolish it anyway.

In other words, contemporaneous with the Chevy Corvair, and pre-dating most modern safety regulations.

Hey! I liked my Corvair. I learned how to drive in a Corvair. It was also the car father/son project where I learned I had no interest in being a grease monkey.
