DIY install of Juicebox Pro 40

Looking at installing a JuiceBox plug-in (or hardwired). The only difference seems to be two and a ground, or three and a ground (THHN). This wire is stranded from this ebay guy. I think it's all going to go swimmingly. Any one have any pointers on the install? 3/4in EMT conduit, and a NEMA 14-50R plug. A 50amp dual-pole breaker.

Several comments:

#6 Cu is required for NM cable, as it is restricted to its 60C ampacity.
If you are running EMT and THHN/THWN, then #8 is sufficient, the 75C ampacity of #8 Cu is 50 amps.
Be sure to ream the cut ends of the EMT.
Properly installed EMT is an EGC itself, so you can omit the wire type EGC, and just run #8 red, black and white.
If you do run a wire-type EGC, then #10 Cu is good for circuits 21-60 amps.
If you hardwire, or use a 6-50 receptacle instead of a 14-50, you can omit the neutral.
Big box stores sell THHN/THWN by the foot in various sizes and colors.

Thanks Wayne!
