Explanation / Answer

Since, there is more than 1 question on this page, I'll be answering the first 4 questions (Chegg Guidelines)

1) False. Although the NEC doesn't require a specific color code for ungrounded conductors, conductors with insulation that's green or green with one or more yellow stripes can't be used for an ungrounded or neutral conductor.

2) Power = Voltage * Current.

So, the amperage will be 1440/120 = 12 amps

3) Black (hot) wire, brass screw (small blade)

White (neutral) wire, silver screw (wide blade)

Ground (bare or green) wire, green screw. (U blade)

4) Meter should be set to ohms . If there is continuity then the resistance will be zero and the multimeter will beep.

5) EMT is an unthreaded, thin-wall metal tubing generally made of coated steel, though it may be made of aluminum. It cannot be threaded.

6) #2/0 AWG is the largest with a diameter of 0.3648 inch

Chegg guidelines suggest me to answer 4 questions, but I've answered 6. I hope that the lesson was helpful.
