3 Phase 208V Control Panel for 3 or 4 Elements

Wow P-J thank you. You are a legend. I am going to make a quick decision on the heat sinks and get started on this panel in a few weeks. I will post my progress for you guys.

Here is the updated schematic with contactors.

Thanks so very much for posting the full scale image so that others could see the adventure. This helps me think that I am also helping others on this forum with ideas about brew systems..

Thanks!! Oh.. and I'm really pleased that I could help you in your adventure.

Wishing you the best and hope your system is VERY successful.!

Edit:
PS: An after thought:
Here is the link to the contactors:

Is this you Doc Jones by any chance?

No - My name is John

Thanks for the reply, I happen to building controller for his 5bbl setup and I know he just signed up.

Cheers

Will the components and diagram work for 220v 5500w elements instead of 208v 5500w?

It could but it will require some very serious wiring diagram changes.

See if you can figure it out.

I spoke before I looked deeper into it. At first glance it looked fine, but then realized it needs work.

Will report back with what I think is right.

P-J, Why the "Serious wiring diagram changes"?

Most 240V/3PH Delta xFormers have two legs measuring 120V-Neutral (X0).
Better make sure you pick the right two though:

(Ignore the circuit breaker info)

A slightly simplified take on the process.
It helps if you look at the wiring as 2 sections, the control circuitry and the heater element circuitry.The link between to two circuits in a contactor system is indirect. The low voltage power to the SSR's is the switch that activates the high voltage circuit. It is difficult to visualize from a drawing, but after construction it becomes very apparent. And with the wealth of information that P-J has provided you can build almost any configuration you need.

I took P-J's 208 diagram and and adapted it for a 5BBL system that uses only a BK with 3 -9kW elements and RIMs using a single 5kW. In place of an HLT a modified commercial direct hot water heater capable of 160 degrees. The hot water was needed in the brewery anyway and we simply added a mixing valve to reduce water temp to plumbing system.

Regardless P-J saved many hours of work for me as I tend to proto-type, then create a diagram - then do the final build. I am a tinkerer by habit.
Thanks, P-J

Hi all, a Dutch brewer here. Our country has tbe option to have 3 phase power on 220v in your house as our code dictates that you van legally only have a 25A breaker...on the flip side GFCI is mandatory.

Anyway long story short, given the awefull weather here and cleaning out the basement it is time to go electric on a bigger scale which includes a 5500 watt element and indeed...5500 / 220 is exactly 25A so I need to go three phase.

Electric brewing is not as advanced here, beyond the GF etc., while my goal is to set up a 3v HERMS. So I am wondering if any of you has the final schematic of PJ (god he is missed) and/or a parts list laying around to help me with the construction. The plumbing seems to be straight forward (and hard to kill yourself with) but I really want to approach this wiring with some respect.

Sorry for kicking up an old topic, I have gone through all the older posts but haven't really found what I am looking for...yet.

In amy case: Happy brewing
