They know not what they did! So this is an outdoor-rated "NEMA 3R" panel. You notice there's a very particular "dance" that the swinging door cover does in order to latch in and provide watertightness. As such, the deadfront cover has a very specific correct orientation. Therefore my original theory - that they put the deadfront on ...

If this was new construction and an inspector saw this, he's make you pull new wire. Since it's existing, wire nut some extra wire onto the short piece so you have room to work with the switch. Never, ever cut wire in a junction box. you never know when you might need it.

I can think of nothing in the national electrical code prohibiting such an installation.

The TR rule applies whether you get a permit or not. I install TR in every receptacle location. They cost about 60 cents more than the baby killer open outlets. IMO open outlets should not be sold anywhere.

The most important rule in NEC is 110.3(B), which requires you to follow labeling and instructions... which means read them. In this case, that only makes things better, particularly the boldface in 4a and 4b. These explain how to use Leviton's "back-wire" feature, which allows placing 2 wires under each screw. Pay heed to the word "FIRMLY&...

Adding the short wire is called pigtails and it is code compliant so yes you can do this. Pigtails are a superior way of making connections in my opinion. The pigtails do not add to the wire volume in the box.

No way! That panel won't pass any competent electrical inspection, mostly because the NEC 110.26(A) clear working space has clearly been infringed by the washer/dryer combination. Not your fault, I know, but as long as that trash? can to the left can find another home, it should be possible to move it one stud bay to the left with the aid of some junction ...

The clearance requirement is almost definitely going to be an issue. (And not an unusual issue - I will have the same problem if/when I ever upgrade my panel and get it inspected.) The shelves should be OK because you have room to the left. But the washer/dryer (whichever one is closer to the panel) is a definite problem. If there is any way to move it (but ...

Any panel has a bus rating (the redline maximum). Some panels also have a main breaker. So yours is 200A. That has no bearing on the wire size. The subpanel has feeder wires coming into it. These are sourced from a supply breaker in another panel, let's say the main panel. You can use any size feeder wire that is appropriate to the actual loads in the box. ...

You question asked "need", that implies asking what the minimum size needed. The NEC doesn't specify a minimum size feeder for a panel, the rating of a panel is only the maximum allowed. Minimum feed is load dependent. The attached load is calculated then adequate wire for load is selected for load, then breaker in the source panel sized to not ...

The 2015 IRC changes section R312.1.2 Height of guards. From 2015 forward the section on guard height "shall not be less than 36" in height as measured vertically above the adjacent walking surface or the line connecting the nosings." The 2015 IRC effectively rescinds the requirements to measure the guard height from an attached seating bench. ...
