Safe to leave transformer open?
 

Just wired in a new 208V to 230V boost transformer for my compressor. These things get hot so I both mounted it on my old compressor tank for 360º cooling and left the bottom cover off.

Any reason why the cover is necessary in this scenario?

When you invite the first grade class field trip in, you may want to have it covered. Otherwise, I wouldn't think it would be a big deal.

rodents or bugs? im especially wondering about biters or stingers

nm indoors

Then only if you are subject to aby kind of inspection

The lower cover is part of the ground path if wiring shakes loose and has to hit something...

Cover keeps someone from running a fishtape, wire or random object into the marrette or wire nut connection. Better to have it covered.

Good thoughts, thanks, I hadn't thought of these. The yellow compressor is just a tank so it's not vibrating, which I know all about since just the other day I put my wine decanter on top of a speaker and then a good song came on the radio so I turned it up and the decanter vibrated off and shattered pretty spectacularly.

Bill, the compressor is in a storage room that only I would go into but your point is well taken.
