I have nearly all the parts together to complete my RIMS build this weekend. Sawdustguy's Dummies thread has been instrumental in the design and will be nearly identical to thatAuber PID, 20A relay, 1500W element etc. Because I have an interest in not electrocuting myself nor an interest in frying new components, I am considering adding fuses. Here are my questions:
1. Is this necessary ?
2. My current thinking is 25A fuse for the SSR, 2A for the pump and .25A for the PID
3. Any "special" tricks or things I ned to be aware of when adding fuses to a line?
