A set of drawings would be a great help. I know it doesn't provide a layout but it will show me what components should go and in what order.
They are a bit "agricultural". You seem to have been persuaded to use DIN rails so these become an option:
https://www.expertelectrical.co.uk/din- ... nal-blocks
That's a bunch (Expert Electrical) who I've used without complaint (far from it) previously.

I have to apologise for bringing DIN rails up. I thought the "Electric Brewery" used them, but my memory is deceiving me - it doesn't! But you wont go wrong using them. Here's a piccie of my "distribution box". It's a bit chaotic because it's having some "enhancements" patched in, but you can see those terminal blocks along with the circuit breakers (five of 'em a far end, 1A for control circuits, 6A for general circuits, 10A for minor elements - RIMS and secondary HLT - and two 32A for the gut busting 6kW HLT and boiler elements). There's also a 12V supply and four contactors (2x 40A and 2x 25A; yeah it's not a 3V system, I've got to be different so it's a 4V system). Yes I have got drawings, but you'll thank me for not encumbering you with then.

Now what was I doing prior to this … Ah yes, my razor sharp memory comes to my assistance again … what did I have for breakfast?

I thought din rails would be easier than tapping holes and ease of install or uninstall.
Your box seems a bit busy and very daunting to an untrained eye like mine.
My intention is to hopefully source a stainless enclosure or worse case a mild steel one. Making holes is not a problem as I can do most of it at work. Just wont be so clever if an opening is wrong.
Do steel enclosures contain a suitable earthing point or not depends on what you buy hence LeeH telling me I need earth terminals to.

Yes they come with stud welding connections.

Earth terminals will make it tidy, and compliant (not that it’s a big deal for your panel)

Let me know when you have them, I’ll delete the links.

I would interlock the RIMS (if you have one) through pump 1 switch as I destroyed an element last year.

The timer is now temp indication from the heat exchanger outlet.

Also the speed controllers are very handy for fine tuning flow, but cause electrical noise and 1 failed last brew. So both are linked out medium term.

The enclosure is too small, that why the door is a dogs dinner.

Wow that panel is very impressive!

When you say speed control, is that done through a phase angle controller out of interest? Edit: just thought phase angle only makes sense
for AC pumps.

It looks like lots of your connections are spade based, what crimper do you use out of interest? I need to get one
sometime.

Bootlace crimpers for stranded wire, not solid cores.

Thanks! Just noticed your green ammeter / voltmeter displays, where did you get those from out of interest?

Thanks for the plans I see you have a rims system and you are using 2 x 3kw elements for your boiler.
I'm going to go herms so the rims element doesn't need to used in the build.
My extraction seems a bit more complicated than yours though I open a window at one end of the garage then open the garage door very technical stuff.
What I can see in your panel
Top row is mcb and 24v transformer. Second is contactors 4 x for elements and 2x for pumps?
Third row ssr x4 and the other 6 unsure what they are. Bottom row is L N E terminal bus white box in middle unsure could be a transformer.

I'm going to chip in there! I imagine "LeeH" has based his design on the "Electric Brewery" as is mine. The "Electric Brewery" design seemed to have the intention of supporting RIMS. So "LeeH" and I pursued that "intention" to make it do what it seems it was always the intention to do. So electing not to have the RIMS stuff should only require not fitting a few bits.

The other advantage of "LeeH's" build over mine (apart from it obviously being neater) is he hasn't suffered my characteristic error of cramming everything in as small a box as possible! Give yourself plenty of space. And don't track 24V (or 12V) lines in the same bundles as the 230vac lines. All the low energy LED indicators often used these days will light up like a Christmas tree due to all the "induced voltages" (they are murder to trouble-shoot hence they are called "ghost" voltages).

In actual fact, The Electric Brewery site is a firm supporter of HERMS and doesn't recommend RIMS with their particular set up (see http://www.theelectricbrewery.com/forum ... hp?t=28112).

Thanks, I've read that now. I do not doubt he has a solid preference for HERMS now. But these designs evolve, and the fact that there is a ghost of a RIMS system in the design that can easily be "woken" suggests he might of been in two minds originally?

"LeeH" might chime in with his opinion as in my last post I could be guilty of putting words in his mouth. Personally my RIMS is now unused (my design was a RIMS/HERMS hybrid) and my own design evolves to enhance HERMS by other means (although the RIMS tube is still functional it is now just a curiosity).

The problems with RIMS listed in that link are easily worked around with the electrics, but I still prefer HERMS. RIMS is proving to be the most durable of the designs so HERMS will probably become obsolete in time (the Grainfather and its many clones are all RIMS designs, if a bit distorted in many peoples' view of a RIMS system).
