TW is still legal and good for 40 Amps. You can run 5 #8 AWG in a 3/4" conduit so 4 hots and a smaller ground (see your instructions for additional wiring instructions) will fit in your conduit. Yes, you can use tape on the ends for identification purposes but your ground has to be a green wire.

Install it properly with clean metal-metal contact. Don't just hand-spin the conduit nuts, get a screwdriver and hammer and tighten them by putting the screwdriver on the serrations made for that purpose and tapping. On the conduit compression fittings, tighten those with a wrench. On setscrew fittings, tighten the setscrews with a tool. Since metallic ...

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.

Those hangers will stick out and potentially catch on clothing. I would use saddles.

For EMT (anyway) the spacing is pretty clear - I can't recall if it's the same or different for other types, but it might well be the same. Within 12" of each box. 10 feet maximum spacing (1 clamp per stick of conduit, minimum.) You can do more than the minimums without an issue. You can't do less than that. So a typical 20 foot run would need at least ...

With the tabs intact the receptacles both are always hot, no electrical safety issue when the outlet and switched outlet are on the same breaker. I have been called in for this more than a few times when a home owner replaced receptacles and did not notice the tab was originally broken. I have seen the switched receptacle and the other receptacle on ...

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 ...
