Hot tub wire type

[olly]

What install / wire to you use:
If you have an outdoor breaker panel and you drop out of the bottom with PVC and then LB inside to the basement, then run across the basement and pop out and install an LB up with a riser into a hot tub disconnect.
Since 6-3 CU NM cannot be installed in a PVC conduit outside. What do you do? A J-box on both ends to switch from THHN to 6/3 NM is no good. Installing a raceway through the basement isnt either.
Is there a 6/3 cable that is rated to be installed in a outdoor raceway.
Sorry for the rookie question. I don't do a lot of Hot tubs

Sounds like a job for SER to me.

There is always 6/3 UF or use aluminum to the disconnect (SER) as Larry stated and copper into the tub

10-4, Thanks! What size LB would you recommend for #4 AL SER?

1-1/4" should do it.

I would use 2" to make it easy

And I'm thinking that, with two nipples with the LB between them, you could easily use 1" PVC.

I don't think so Larry I believe you would never get it in one inch
