Then at the subpanel I would still use the two (HomeLine) 15a breakers for the current 110v needs (lighting and stuff). For the 240v dryer I would install a (HomeLine) double pole 30a breaker. Lastly, next to the subpanel I could install one of those 50a gfci spa panels, and from that a 50a outlet for the brewery. I know I probably wouldnt be able to run the dryer and brew at the same time...but that is not a problem.
Thanks for the picture and this sounds good. NOTE step 6.
(1) remove main GE 30amp and 20amp breakers to garage.
(2) install GE 60amp or 75amp breaker to garage
(3) feed 6 gage THWN wires (rated 75 amps) through existing pipe to garage. Ground per main or sub panel.
(4) install 12/24 circuit panel in garage. Either surface mount or recessed - depends upon your setup.
(5) in garage sub panel, install appropriate sized breakers for outlets and lighting. 20amp for 12 gage wire and 15 amp for 14 gage wire.
(6) FORGET the spa panel!
(7) install 50amp GFCI breaker in the garage sub-panel for your HERMS setup. Then you can have an outlet with cord to your HERMS or hard-wire the operation from the sub-panel.
Yes, you are approaching the load limit for the house. I don't think you will be running the AC, dryer, stove, and HERMS system at once. But, at least you will be protected on the branch circuits and main.
