Mounted the contactors on the inner panel today. Took the time to drill and tap the screw holes for mounting. I used 10-32 Phillips head pan screws.

Those kind of switch blocks are used in aerial lift equipment. (Scissor lifts, boom lifts ect.) United Rentals, Sunbelt I would think may have them in stock.

I bought those at the local Home Depot. They were a stock item in the Plumbing Dept. with the water heater parts. The pic on the left is the BK.

The SSRs are installed and switch lamp bases and switch blocks are in place. Next will be the contactors on the inner panel.

Yes it may be possible, but if you are asking this question I would suggest calling on an electrician. Not being sarcastic just concerned.

Finally finished fitting and completeing exterior components installation. The selector between the two top PIDs is to allow only one kettle at a time to operate to prevent amp overload. (Left PID is HLT, right BK) The white pull knobs on each side are for the element contactors. The stop switch...

It would be best to separately fuse/C.B. the pump from the rest of your components. The pump should have the amp draw on the motor label.

I think 50A is cutting it a little close but I understand that on a budget going up to 60A is a lot more expensive. Check out ElectDirect they have good prices on 2 pole 30A contactors ($13.10 ea.). I just bought some from them.

The measured clearance is 1 1/2" which seems sufficient, as shown in the pic. The elements in the BK are ULWD. The HLT elements watt density was not a concern.

I'm building using (2) 5500W in each (HLT,BK). ULWD in the BK, purchased at Home Depot. BK is pic on the left.

The contactors and power distribution block came today so it's time to figure out the panel layout. The contactors are 2 pole 30A used to isolate the SSRs. The fuses are for the elements and breakers for the pumps and panel control circuit.

My kids school got extra points for the massive label.

I work as a maint. mech in a scrapyard. They came in as scrap stainless. (1) 55gal. drum, (2) 200L vessels, (2) 60 gal. pots. Its like working in a candy store.

Those are the 1/4s. For ten bucks more they'll be easier to see. (The eyes aren't as good as they used to be).

The control panel build needed to get creative as the panel was used and had extra holes. The stainless front seemed to do the trick. Just trying to get some ideas of the placement of the knobs and buttons. PID controllers are fitted in place. Thats it for now!

More pictures of parts and goodies. The frame still needs cross supports. I'm thinking of decking it with Trex. It's 10' x32".

More pics. Drilling kettles for the elements. The control box rough cut.

Time to start the build thread as the system is progressing along. I'll try to be diligent and post pics.

I work in a recycle yard and those are probably worth $75-$100 ea. scrapped. Nice pieces, I have some similar to those. Saw some new ones on line going for over $800. (Sorry, now everybody is pissed).
