Are the instructions asking for a 6 AWG ground conductor, such as would be used for Equipotential Bonding (does it say solid or stranded), or a 6 AWG equipment ground conductor?

My original post was regarding the EGC and not the #8 solid equipotential bonding conductor.
The tub instructions did not reference the EGC and so I planned to use green #10 cu for that purpose (50 amp circuit), but was told by the supervisor, "we always use a #6 EGC as some hot tubs require this." I have never come across this.
That is the origin of my question.

I am now guessing that few hot tub manufacturers, if any, require this "full size" EGC and sizing per 250.122 would be the norm.

Thanks

Don,

That leaves me confused. :)

I definitely am not going to deviate from the instruction provided with a hot tub. :eek:

Bob,
My statement is too broad, the listing does involve the wiring methods as you have pointed out. I still highly doubt that the EGC size in this case is part of the listing. I'm not saying not to follow that instruction, just that I don't think it has anything to do with 110.3(B).
I didn't have any problem saying that all manufacturer's instructions were required to be followed by 110.3(B) until UL screwed it all up with the "classified" breaker issue. Now, I always point to that, to say that not all manufacturer's instructions are not 110.3(B) instructions. How does the installer know what is what?...I have no idea...
