This had me wondering so I looked up the 65l Brewzilla. It calls for a NEMA 6-30R plug, which sorta looks like a face, but it's just 30 amps and the heating elements are a total of 3500 watts. I was going to say you could maybe get a breaker for about $75 but it really depends on your style box. I think I paid $65 about 2.5 years ago. I did find a really inexpensive
GE 2 pole GFCI for $51.84. Forgive me if you already know this but you should check the model of your breaker box and see if the model # of the breaker works for it. Looks like those NEMA 6-30R outlets are about $10-12. Maybe under $100 if you are just changing out the outlet or a short run of line from the box but still wondering about that 50 amp reference.
