I have one of these:
http://www.homedepot.ca/product/air-conditioner-disconnect-switch/943214
This is a non-fused, 60amp disconnect switch, with a plastic pullout attached to the contacts. I've purchased it to cut the load between my SSR (240v, 30amp lines) and my element. Or once I put it all together, that's what I purchased it FOR.
Is this safe to pull while there's load on the lines, like say in a worse case my PID screwed up or my SSR stuck closed and 100% power is flowing through non-stop to my element. Can I yank this disconnect safely?
I wanted a proper 30amp DPST toggle switch but they're impossible to find here. Ditto to contactors, crazy expensive and special order only. Nuts.
I'd be thinking I'd want this in order to fire up my system without the element having a chance of being "on", then when I want to monitor my kettle cooling after the boil, pull it so I can rest assured I'm not firing the element while trying to cool the wort.
