Stuff I see the most.
Knock out seals missing.
Agreed, biggest one I have noticed.
Stuff I see the most.
Overfilled boxes.
Agreed, for the most part.
That has to be second best.
Stuff I see the most.
Switches not grounded
I noticed that too, but not that often, as you would imply it.
Wouldn't that be an inspector oversight as well? I mean, I can hide MANY things from an inspector, but kickplates? hard to miss them. Don't take me wrong, I'm not defending the EC who does that here, but I think the inspector is just as resonsible.
Stuff I see the most.
Romex stripped and used in AC discos.
What is wrong with that?
#2 AL SER to sub panels on a 100 amp breaker.
What's wrong with this also? If we're talking resi. Besides this might be an old wiring that was code back then.
Romex in underground PVC runs to out buildings.
I assume you mean NON UF rommex? Otherwise I'd still agree, UF cable doesn't need conduit.
Wrong size/type OCPD for AC unit.
Hard to "wrong size" the AC's. between the MCA and MOCP the range is so great, I hardly ever seen one not being either or.
I agree with this, however, it's a fairy tale. Ain't gonna happen. If all electrical violations will be fixed one day, we'll still have mislabeled panels.
and my favorite:
10/2 NM to a dryer.
Why is this your favorite?
The old code allowed dryers and ovens to be wired with 3 wires. That's why(even now) they STILL sell 3 wires 30A dryer receptacles, 3 wires dryer cords, 3 wires 50A receptacles and 3 wires oven cords. I seriously doubt anyone's attempting new installations with that configurations, and definitely not that often to be a favorite.
