I'm gonna cut straight to the point.

I'm wiring a hot tub for a friend. I have the wire size determined, I'm verifying hydro usage to permit me to add it to the 100 amp service (all gas appliances so it should be no problem). I have a location within site for the spa pack outside the 10' minimum.

Now, The tub is 40 amps. I'm running #6 copper from the spa pack to the tub. Can I add breakers to the spa pack down the road? I know that there will be space for 2 full size breakers in the spa pack in addition to the GFCI breaker. If it's permissible to add breakers to the spa pack for stuff (like new outdoor receptacles... Considering I'm disconnecting the 2 that are there because they're inside the no-go zone around the pool), I want to run something like #2 aluminum to feed the spa pack and stick it on something like a 70 amp breaker (this way I can add 15 amps without issue, although I suppose 60 on #6 would still be big enough for a 40 amp tub and future 15 amp loads...)

Thoughts on adding breakers to the spa pack for non-spa items?

Not a lot of room in those spa pac enclosures.
Could have problems trying to bend that #2 out of the way

i think there is an arc fault rule that would need to apply to that extra breaker

That's why I like the Midwest spa packs. They are actually a 4 space 8 circuit panel, and they do give enough room to work in.

I normally use a siemens spa pack and they're the same.

I don't like breakers outside - especially gfci ones. Every outdoor surface around here is wet with condensation or rain for 3-4 months solid.
I've almost always installed the GFCI for hot tubs outside. Rare cases I've put them inside with a regular disconnect outside.

If I put the GFCI spa pack inside I still need a disconnect outside. A weatherproof panel with a breaker is usually what we do, but if you don't like putting breakers outside that leaves a non-fusible disconnect... What would you use then? a 60 amp AC disconnect? I don't trust them for any large loads other than AC's...

That leaves a 3R 60 amp disco...

I trust the dirt-simple AC disconnect outside. I also don't need a feeder breaker in the main panel because I put the gfci there.

Why don't you trust an A/c disco for anything other than A/c? The disco doesn't know what itsattached to.

I've had some of those a/c discos get heat damaged on higher loads. We don't even use them for EV chargers. Yes we could, but never do, due to them ending up needing replacement down the road.

I don't wanna pay for repairs to a hot tub because the disco melted and the tub freezes lol
