Hey folks, I just finished putting together my full electric control panel last night, and it's perfect except for a (pretty big) snag. I've wired my BK control up using a Potentiometer and an AC control SSR; when I turned it on, it worked great, and it heated REALLY fast -- I got 5.5g from 50f to 160f using my 5500 element in 10 minutes. A few minutes later, just as a I was about to hit a boil, I heard a loud "pop" and smoke starting leaking out from the panel.
The SSR itself had gone poof -- distorted, melted, and the inside is completely charred black -- easy to see this since the popping noise was the front plate piece popping off.
All connections are tight, wires are correctly sized, and there's no evidence of burning or charring anywhere else but the inside of the SSR itself. What puzzles me is what would have caused it to burn up; it's a 40A SSR with a load that's only 22A or so.
Does anyone have any thoughts or aha moments that come to mind?
