Crawl Space Junction Boxes: inspection and capping
Hello. I'm in the process of crawl space improvement. I snapped the photo below as I see it warrants a junction box cover. Most of the junction boxes in the crawl are affixed to the joists (still lacking covers, but all wires capped). This one is hanging down which is bothersome to me.
Do you see any obvious wiring problems in this box? The other jboxes seem fairly consistent wrt number of wires and capping). I believe this was installed mid 1970's.
If no wiring problems (e.g.,fraying, blackened wires, wrong gauge wires), is it a matter of hiring an electrician to apply the covers? I think there are about twelve of them in one crawl space, almost all firmly attached and all capped. How can I get the one pictured below better secured? Btw, I have removed all of the debris, cleaned up all the tar sprayed on and other, and installed proper membrane to side. Floor does'nt look like that anymore.
Thank you for your advice.
