My uncle is giving me a table saw that is 220 volt for my basement problem is I only have room for one 20 amp breaker and right now that is sometimes used for a 220 volt vat that needs the 20 amp breaker. I gave ESA a call and they said I can use a double pole single throw 20 amp switch and use the one 20 amp fuse for both as long as only one is on at a time. Now I don’t know if I misunderstood him or not but how do you connect two 220 volt things to one dpst switch, it would make more sence to have two dpst switches connected in line to the 20 amp breaker.
Basicly I want to be able to turn one off and turn the other on and visa versa.
Please help

Well, you can put another outlet on that circuit, or you could add a subpanel, or you can replace some of the 120V circuit breakers with what’s called “tandem” breakers, they essentially put two 120V circuits in one space…freeing up spots for another 240V breaker. I’m not sure they are available for every panel made, but certainly the more popular ones. The easiest might be to add another outlet, or they make duplex 240V outlets, something I only learned recently in another thread on this forum.

+1 Fred Tandem breakers can be found to fit most boxes. It is a simple straightforward fix but if you know little or nothing about electricity get someone that does or pay a pro. On another thread insurance was listed as many peoples reasons for not doing it themselves, it is something to consider.
