It’s hard to “overload” a box, though it might be full.
As long as all wires are secure and each circuit has the proper load you’re probably find. Just get another box if you need more circuits. . . oh, and if you don’t know what you’re doing, hire and electrician or somebody who really does know what they’re doing.
Electrical arcs are the #1 cause of house fires.
I don’t know. It’s a “200” box and the thingies add up to way over “200” and handyman guy said “Wow!” It’s been like that for years. Ain’t nothing burned down yet in spite of my For Sale By Owner posting in July 2008.
