I never said I wasn't using contactors. I have 240v contactors that are ready to be installed. I was trying to figure out the best way to control power to the elements is all. i.e. a switch directly to the element vs a switch routed through something else.

Aw! My link didn't work - I wasn't referring to the switches you linked to. I was referring to these ones: https://www.ebay.com/itm/CUTLER-HAMMER-SELECTOR-SWITCH-10250T-HEAVY-DUTY-AC-600V-STANDARD-DC-250/312055954192?ssPageName=STRK:MEBIDX:IT&_trksid=p2060353.m1438.l2649 I'm pretty sure the...

I found these selector switches able to handle the necessary voltage but can't find amperage info anywhere. Will these work?

Damn, just noticed that with the switches. Better now than when I have everything wired up. I bought them initially to be my on/off switches for my pumps and they came as a lot of (4), was hoping I could use them for something else but clearly not. I suppose the question is now: what switch...

I have a digital thermocouple in the HLT and, yes, was going to switch off the element, mash in, fire up RIMS + Pump from there. 3 total elements. 4500w in HLT, 5500ULWD in BK, and 1500w in RIMS.

I mistyped -- I have these switches (https://cdn.automationdirect.com/static/specs/cents22mmselect.pdf) not a DPST. I'm trying to figure out the best wire up my elements?! so that they are ultimately controlled by my EZBoils to regulate RIMS temp and BK. I have one element that I plan on...

I think this is the route I will go as I already have a few extra DPST Switches available to use. I'll have to check my SSRs to see if they are 2 pole or not? @passedpawn - do you have your wiring diagram I could take a look at?

Makes sense about the reasoning and I'll keep the two I installed currently to power on/off my two pumps since those will be manually controlled during the brew. Clarification question then: so the reason to wire a manual switch to the contactors would be as a fail safe option then?

Sorry, I should've provided a few additional details. I will run (2) Auber EZBoils to control RIMS Mash and BK. In between the EZBoil and the elements there will be contactors, fuses, circuit breakers, and SSRS. What I'm asking is if I should wire the elements to a simple manual selector switch...

I'm trying to finish up my control panel build and had a question on wiring up my heating elements. I have two 240v elements in the BK and Mash Tun as well as a 120v RIMS. My question is this: before I install additional switches to power these is there any reason not to just wire them directly...

I'm also running 30amp 240v to my control panel via a spa panel. My two pumps are 120v, my two elements are 240v, and my RIMS element is 120v. In this case I would need single pole breakers for all the 120v items and dual pole for the two 240v elements, correct?

Thanks for all the info, I've already been looking at grabbing enough din rail mounted breakers to cover my devices. Looking around eBay I've only seen different AMP ratings with voltage of AC230/400V and can't seem to find a whole lot rated 120/240. Will these breakers work...

Yeah, I understand that and it makes a lot of sense to me as well. However, I thought I recalled reading in various threads that the relays, contactors, and fuses would all blow/fail before a fire would result from the lower AMP rating of the wire? Maybe I am misremembering this, but I'm not...

As I've been reviewing a lot of P-Js diagrams for wiring up my control panel I've been noticing additional breakers within the control panel. Is this just for additional protection? I'm asking because if I'm using a spa panel with a 240v GFCI protected breaker and then have the breaker in my...

I'm in Chattanooga and interested in the grain supply and grain scale. PM me with pricing/info please

Ok, thanks for the clarification. Should I just go for the 8/4 RV cable to be safe(er)? The price is comparable with what I've found on eBay. I'll have to swap plug ends regardless...

Yeah, I knew that one. I've been waiting on an electrician buddy of mine for a while now and he says he's going to get around to installing a 240v circuit in my garage. Until then I'd like to brew... So, yeah, I guess I'll find some 8/4. Back to my very original post, maybe the best bet is...

So do I need to go 8/4 in order to be safe and drop 30a plugs if I want to go this route? It's confusing sometimes with so much conflicting commentary on the threads. Some say 10/4 is more than enough, some say it's no where near enough...

Really? I've read up and down these forums (in addition to plenty for sale on Amazon, eBay, etc) that 10/4 can handle a 30amp load.

Agreed. ;)
