Sorry if I missed it earlier but I'm curious what outlets and plugs you used for your heating elements. I'm building now and don't like the big bulky options I see others using.
I used the Blichmann Boil Coils and the cords that were supplied with those.
The receptacles are Leviton 2620 (http://www.leviton.com/OA_HTML/ProductDetail.jsp?partnumber=2620§ion=40369&minisite=10251)
The realty of 240V is that it is bulky due to the required separation, although i don't find the Blichmann plugs or Leviton receptacles to be overkill.
