I am trying to decide if I really need 50a service from my breaker box. I have a new house with plenty of room in the box so that is not a problem. The cost is significantly greater though and I am slowly getting SWMBO's approval but keeping the price down makes it easier to convince her. I am trying to figure out what the advantage is to having 50 amps is. I only plan on 5 to 10 gal batches and batch sparging in a cooler mash tun. It would be 2 tier with one pump maybe upgraded to single tier HERMS with 2 pumps later on. I would like to use 2 5500w elements but could use 4500w if that would be too much for 30 amp. From what I have read it seems that I just wouldn't be able to run the BK and HLT at the same time.
