I am planning on building a wood workshop attached to my garage. I have a 220 line already on the outside wall of my garage with two 20 amp breakers. Can I install a 60amp sub box in place of the 220 line (which services my hot tub) and run 110 curcuits off that box and still have my hot tub? If not, what guage/breakers do I need to run from my current service box to the new sub box?
