Hello all! I’m new to the forum, but not electrical industry. Used to work
in high voltage utilities now working in the residential sector.

Anyway, working on a job where the customer needs some interior wiring work done as well as connecting their new hot tub. They already have a Eaton CH 4 circuit 60 amp gfci sub panel installed when then built the house. 60 amp breaker feeding the sub panel from main panel.
Customers new hot tub requires a 50 amp gfci sub panel. I’m trying to save the customer some money, but not sure if the 60 amp gfci would be ok to run the 50 amp hot tub. Of course would use the proper wire for 60 amps to the tub.
One of the guys suggested moving the 60 amp gfci to the main panel and installing a standard 50 amp in the sub, but I don’t think NEC would like that! Ideally, I would like to just connect the tub to the 60 amp. Any suggestions to help the customer out?

thank you.

What is the exact wording for this on the plate or manual?

I actually don't see a problem with that yet. IF it wound up being the convenient way to do it.

I don't see a problem with it either.
 
They don’t have the tub yet, being delivered next week. So unfortunately I don’t have the nameplate.
However, They gave me a copy of the manual. The manual says it requires an isolated dedicated 240vac 50amp circuit. Permanently hardwired installed in grounded conduit. That doesn’t sound right. Should be able to use non metallic conduit.

Thanks again.
 
So that’s now three electricians saying no problem putting the 60a gfci in main panel and a standard 50 amp in sub panel and just me saying just wire the 60 amp gfci sub as is to the 50 amp tub would be ok...

I haven't ruled that out yet, based on receiving more info. And it's my first instinct.

If it must be 50A, why not leave the spa subpanel as is and feed it with a 50A normal breaker in the panel? Then all wiring can be 50A, and the spa breaker is not the OCPD, but just GFCI protection and disconnect. This is exactly how I would do it anyway.

This is a good idea as well. Didn’t think of this!
 
If the tub calls for a 50 amp circuit then the 60 amp would not be compliant. Do they even make a dp 60 gfci? I guess so but I have never seen a tub that needed it. I think I have had this conversation before...:D

As would I. I was ready to suggest it had I not been beaten to the punch.

You also avoid correct-brand issues in case panels are not same brand.
