Johnson A419 and 220V

[theknub]

Looking to move to an electric brew system. Would like to purchase a 4500W element and know that I need 220 to safely power it. That being said, can the Johnson A419AEC1C be used to control the element? What is the correct wiring for 220? I'm pretty sure I understand it, but just would like to verify.

Thanks

The relay contacts for that controller are rated to 10A max, so you're not going to get 5KW out of it on a 220 vac feed...

Cheers!

ahh, and that is what i missed and why i ask. any recommendations besides building a control box?

thanks for the input

You could still use the Johnson or similar "under-powered" controller if you add a hunky external relay and a small transformer with an output voltage compatible with the relay coil. Use the Johnson to switch the transformer primary and you're in business...

Cheers!
