How much heat sink?
Ok,I built my oven 72"x32"x32" it has 3 2800 watt burners the ssr I got for it is a 40amp one,heres the problem I fired it up,the burners started to get warm and then the relay blew up!The center of the relay blew out,the wires and connectors are fine,i had it mounted in a steel junction box on the side of my oven,did I need heat sink?if so how much,thanks.
