I built a controller a while back, but then had a house fire. No one was hurt and it wasn't due to DIY electric. I was able to salvage the controller, but I had to strip it 100% down, clean it up and reassemble it again. It runs a PID for temp control or it can switch over and have variable control using a Potentiometer. I want to install proper fuses before plugging it in.
ALUMINUM BOX BEFORE FIRE:
AFTER FIRE:
I planned to use this to control a Camco 2963 5500W 240V Ripple Foldback Ultra Low Watt Density element.
The PID runs one 40A SSR and the Potentiometer runs a 40A SSR (shown here)
I believe I need a .5A Fast Blow Fuse and a Panel Mount Fuse Holder to protect the Auber PID.
5500W 220V would draw 22.9A (25% more would be 28.75A FUSE). Could I get away with a 25A fuse for each SSR? Should I bump up to 30A for each SSR? I'm having a hard time finding a 30A Panel Mount Fuse Holder.
I could use some input on this.
