biab electric help

[jim6.9%]

Using doug293cz biab 2 pump system. Would like to add a hlt using a 20 amp 110v element for sparging. Have 240v/30a power source. What I'm looking for is help in how to wire a pid to this system for hlt tank and if there is enough power there to just add it with the 30 amps.

A 5500W@240V element draws 5500/240 = 23A. A 2000W@120V element draws 2000/120 = 16.7A. If you ran both at the same time you would need a minimum of 23 + 16.6 = 39.7A. However, if you run a 2000W@240V element, the current is only 2000/240 = 8.4A , so you would need 23 + 8.4 = 31.4A, still too much for a 30A circuit. You could run a 4500W@240V and a 2000W@240V for a total of 18.75 + 8.4 = 27.15A. You would have to run the pumps off of opposite hot lines to keep you total amperage less than 30A.

Brew on

Ok thanks. I have a separate 20 amp next to the 240v/30a, so I will use that one for the hlt. I was hoping I wouldn't have to. Thanks again. The build was easy with you schematics. Even for a person like me who has no electrical background. It works great.....

Hi Doug
Do you have a wring diagram for a 240v, 4500w and 2000w elements with 2 pids think I would like to go with that system now. Thanks

Here is one that I have:

Hi Doug
Final got my panel wired up. Had one problem though, had to have rims pump on, to get the rims switch power on to work. I think the NO red wire from the rims pump to the NO on the rims element switch should come from the same spot as the other element switch, but not sure. Thanks for your help.

That is the way it is designed to work. It is an interlock. Having RIMS power on without flow thru the RIMS tube just about guarantees scorched wort. Why would you ever want the RIMS element on without the pump being on?

Not using it as a rims system, Using it as a BIAB and with a HLT system. Didn't realize it was for a rims system that would make since for that setup, would there be an easy change to make for what I'm doing.
Thanks, Jim
