Has it ever been a violation to run aluminum to a disconnect for a hot tub? The SER would all contained within the structure of the house.

I take that back according to code in 2011 the equipment grounding conductor needs to be insulated copper.

680.42(C) Interior Wiring to Outdoor Installations. In the interior
of a one-family dwelling or in the interior of another
building or structure associated with a one-family dwelling,
any of the wiring methods recognized in Chapter 3 of this
Code that contain a copper equipment grounding conductor
that is insulated or enclosed within the outer sheath of the
wiring method and not smaller than 12 AWG shall be permitted
to be used for the connection to motor, heating, and control
loads that are part of a self-contained spa or hot tub or a
packaged spa or hot tub equipment assembly. Wiring to an
underwater luminaire shall comply with 680.23 or 680.33

I believe enclosed in a cable would qualify

I believe it changed in 2017 where aluminum is allowed

I think that in older code cycles the conductor had to be insulated not under a jacket. I remember running MC cable within the house for this reason.

 

[Dennis Alwon]

Could be-- we need Ken for that. I only go back to the 2005... and it allows the sheathing.

The 1999 NEC required an insulated EGC. The 2002 was changed to allow a bare EGC within a cable within the interior of one family dwellings. {680.21(4)}
