Adding 50 amp 220 v connection for hot tub - gfci
Try to familiarize yourself with the NEC and what is required for hot tubs/pools, there's a specific section of the NEC that talks about hot tubs. It's not easy to read at times but will give you the info. The hot tub mfg should also tell you what is typically needed to get the tub installed, although not code requirements. I ran my electric through my garage wall and then about 90' underground to the spa panel, all 6 ga copper wire (THHN/THWN, 4 wires), then ran 6 ga (3 wires) from there to the tub.
I bought a Siemans 60A spa panel on Amazon along with a Siemans 20A GFCI breaker for an accessory circuit. The 60A GFCI breaker was part of the panel. I'm not sure what you would need to do in order to run the wire through the house, I used schedule 40 PVC for the underground.
Overall good quality stuff? I don't know, I don't do enough electric work to determine, but the name is not an off brand and it's been working without a hitch for two weeks now, every day. None of it is inexpensive regardless, just your labor.
