I was hoping I could run this by someone. I've done other basic homeowner electric work like adding 120 breakers and outlets. From reading online, adding a single 240 volt circuit next to my breaker box doesn't seem that more difficult than what I've done before.

Digiboil 65L : 20 amps 3500 watts. Has a nema 6-30h plug. 6-30h outlets are only 30amps though.

22 ft from circuit breaker.

So I went with a 30 amp 2-pole breaker (square D and HOM like my other breakers) and nm-b 10-2 wire. Will use the neutral white wire as the second hot (and label it red).

Does all this sound good? Should the breaker be gfci protected? I don't believe I need a neutral.

The sales info I looked at showed it with a 3 wire plug so it should be ok. Some electronic controlled devices require a neutral and then a 4 wire would be needed but it looks to be straight 240 so your plan should work. As far as GFCI code specifies 15 & 20 amp circuits so it would not be required but gfci’s around liquid are a good idea.

  • Sorry, Ed. I know that 220 is old-school terminology for 240, but it's confusing to laypeople and needs to die. :)

  • Ok, cool. Thanks!! Why is gfci required for 15 and 20 but not 30 amps?

  • @Fun4stuff - Actually it depends on what the receptacle is being used for. For example pool equipment Article 680 will require it to be protected. So you need to identify what equipment you will use on it and go to the corresponding Article in chapter 6 and check to see if you need protection. I would suggest you do protect it because it is in a damp location and it would just make its use more safe. What's wrong with that. Jan 14, 2020 at 16:12

    @isherwood, the sales info listed it as 220 , I usually do state 240 but if a question says 220 I try to use both or stay with what they asked to not confuse them.
