I need a second opinion. An electrician is going to be connecting my
hot tub this weekend.
The tub is a 240 v/50 Amp unit. He suggested that we use 3 #6 thhn
wires for the hots and neutral and a #8 thhn for the ground in order to
save space in the 3/4'' seal tight. Is having a smaller ground safe or
is this against code? He says he has done this before in the past.

Seems like pretty large gauge wire to me. Depending on the length of
the run, of course, which you don't stipulate. Tom

The pull is about 30 feet.

I think #6 is rated for 50 amps, so that is pretty standard. Just
wondering if a ground of one size smaller (than hots and neutrals) is
ok.

It's very common. A neutral wire 1 size smaller than the hots is also
common. (Not enough information for me to know if either is appropriate
here or not)

Best regards,

It's OK...

It's fine, in fact the NEC requirements for the ground are only #10

I just did this job last weekend. Lowes sells a 3 conductor #6 stranded &
solid ground as a single cable; exactly what you need for this job.

Well, if you don't like his work, then fire him and hire another
professional.

Who is the electrical expert here? You or the electrician?
