/diy/ - Do It Yourself

Originally? No. Now I'm not so sure.

>have 120/240 relay for use on my sous vide
>turned it I and let it come up to temperature from cold tap water, around 15 gallons of water
>set it at 80deg C and walked away
>come back and all the wires are hot, burning plastic and electronics smell coming from relay, the relay label is melted and the potting compound melting out of it, and it's locked in the "on" position
>water is at 90deg C
>unplug everything!
>let cool down
>attach 2 huge heat sinks to the relay
>turn back on after 5 minutes
>good as new
>MFW

All in all, happy.
