Just sent this PM to nostalgia but if any of you can add perspective on the amount of heat from the SSR heat sink, I would be grateful.
"Was curious, how hot do your heat sinks actually get? I just finished my plain jane control box and an finishing up my subpanel wiring in my garage this week. I currently have my heat sink in a sort of crowded box.
I have two concerns:
1. heat sink getting too hot for the space.
2. that I wired my contactors backwards.
the heat sink is clearly the greater issue

Last page of the thread shows my end result pics
At the closest point there is a wire 3/4'' from the SSR.
I was debating about putting a fan in, or cutting slots in the top for the heat to vent out, or cutting a hole in the side wall of the project box and relocating the sink outside the box. Or a combination of each.
Obviously the build got a little crowded in my project box.
You have any suggestions from your personal experience?"
My SSR and heat sink appear to be the same as nostalgias and I am planning on using a 5500w element. Obviously the sink would get warmer with the more current draw.
Thanks all
