"Just to clarify- the wire IS in conduit outside, but for the 6" or so it runs inside the walls, it is just bare wire." Bare naked ground conductor is perfect fine in certain space. The reason the CODE requires the ground conductor to be inside the conduit is for protecting the conductor from being damaged by any mechanical means e.g., gardener weed ...

Short answer: no it is not acceptable it needs to be continuous. The pertinent article of the National Electrical Code follows: 300.12 Mechanical Continuity — Raceways and Cables Metal or nonmetallic raceways, cable armors, and cable sheaths shall be continuous between cabinets, boxes, fit- tings, or other enclosures or outlets. You could terminate ...

Base Conductor Size Start out by using Table 310.15(B)(16), and applying any required corrections, to determine what size conductors you'll need. For your situation, we'll assume we can use the 75°C column, that you want to use copper conductors, and there's no other corrections required. So in your case, if you want to install a 50 ampere panel, ...

If you are installing a 50 amp sub-panel normally you could use #8 wire and use 3/4" pipe. You can fit 4 - #8 wires in a 3/4" pipe so there is room for a ground wire with your two hots and a neutral. If you are installing a 60 amp sub-panel #6 wire is good for 65 amps at 75°C. (You have to use the 75°C rating since no one makes a 90°C rated breaker.) Using ...

To directly answer your question: There is no height requirement for EMT. It can be used at any height on the outside of a house. EMT is identified for use in locations where exposed to physical damage but not 'severe' physical damage. The difference is a matter for interpretation. EMT can be used in wet locations as long as the conduit is galvanized and ...

I would not use EMT at all. It is not weatherproof. Those compression couplers (you know, the not-setscrew ones) are not for weatherproofing, they are for better grounds. I would either go with thickwall with threaded connectors which I would teflon or dope for watertightness, or preferably PVC, which is cheap and easy to work with.

Schedule 80 will be required if exposed (above ground). Annex C of the NEC shows #8 THHN,THWN,THWN2; 3 wires in 1/2" and 5 wires in 3/4". You should be feeding the tub with a GFCI breaker.
