I have a couple of machines that I need connected, and I have brought over 3 electricians to give me an estimate. Each electrician is telling me something different in regards to wiring, breakers, and safety disconnects. I was hoping someone can help clear things for me.
1. Where would I find the correct chart for wire ampacity (different websites show different numbers)?
2. Safety Switches, should I use a fusible on not, and why?
3. What fuse size should I use in a safety disconnect (nameplate amps, or X times the name plate amps)?
4. What breaker size is optimal for a given nameplate amperage (% times the nameplate)?
Please, answer only if you know what you are talking about as I am already confused.
Thanks
