I knew I would goof on an order somewhere, no project can go perfectly smooth!
It may not have been you: There was a period of a few days when I had them listed as 120V lights instead of 240V by mistake. Oops!

What does everyone think of using this relay as a replacement for the power relay Kal's original plan? Its a bit cheaper and looks like it should work fine.

Meets all the specs so it should work. The thing I don't like about those relays is:

(1) The wire connection points. I like nice screwdown points for a good connection. Important with higher currents.
(2) It's 100% potted so you can't see the contacts instead. After many years of use (probably 10+ the way I use them in my setup) you'll may get some carbon/corrosion build-up on the contacts. Having them exposed means you can clean 'em off to like new.

Looks like this one addresses concern #1.

Hi guys,

I've added a new control panel article that details how to add a safe start interlock.

This safe start interlock only allows the control panel to power up if the pump and element switches are all in the OFF position. This interlock will also ensure that if power is ever cut, the pumps and elements will stay off until the operator turns them off and then resets the power.

Adding a safe start interlock to our control panel will avoid harming the pumps, heating elements, and the operator.

See: http://www.theelectricbrewery.com/control-panel-safe-start-interlock

Cheers!

Kal

Kal - Your posts and blog articles give me so much to shoot for. Even though I am a few years away from being to build a setup like yours, that hasn't stopped me from starting to warn the SWMBO it is coming. Sure, she laughs at me today... But still... Right?

Kal,
Great post and links. This is a perfect project for all Sparkies out there.
What was your approx. cost of the total install (controls, kettles, stand, etc.)?
Thanks!

Approx $5K. I'll be posting a breakdown in a FAQ online at the site hopefully soon. I have a bunch of it already written.
