Spa sub panel

Do i need to use a sub panel specifically labeled as a "spa sub panel"

Can i use a 4 or 6 space weatherproof main lug say murry or square d and just add in my own gfci breakers?

And do the gfci breakers need to be in the sub panel or can i put them in the main service and use standerd breakers in the sub panel?

Dose this not make sense or what? Is it recommended to use a pre manufactured spa subpanel?

I think your fine either way but I'll check the code to make sure. Code requires a gfi outlet near the spa are you aware?

It doesn't make any difference where you install the gfci protection. It is more common to use a spa panel as the required disconnect. That disconnect needs to be within sight but not closer than 5 feet from the spa. These panels often allow for a 40 or 50 amp double pole gfci and the addition for a single pole breaker to run your branch circuit to the required servicing receptacle.

Also the feeder wires from the panel that is bringing power to the spa panel needs to be in an approved conduit. The wires all must be insulated and the correct colors.

Installation of a spa requires strict compliance with code for a safe installation. I suggest you download a free copy of the NEC article 680 and use the search engine on this site to research your project.

A spa panel will be cheaper than buying a single panel, then a 50 amp gfci breaker.

There's a few options. A disconnect is required by the hot tub but it doesn't have to be fused. If you can get a gfci breaker for your main panel then go that route and put a cheap $15 non fused disconnect by the hot tub. If you can't get a gfci breaker for a reasonable price, then get a disconnect made for hot tubs with a gfci breaker pre installed

Use a spa disconnect panel like this. It has the 120 volt convenience receptacle included. Easiest way to go.
