[QUOTE="mtnboomr, post: 4352081, member: 52310"] I am a retired journeyman electrician. A breaker is sized not only to protect the wiring, but to handle amp inrush on startup without tripping. While a welder or saw may say it requires a certain amount of amperage to operate correctly, that is the amount of amperage required to run the item with no load on it. On startup, or under a load, the amount of amperage need to run continuously will increase. That 17-amp saw will likely need a minimum of 25 amps to run under a load [B][I](you notice I said MINIMUM)[/I][/B]. Therefore, installing a 30-amp breaker is required. [/QUOTE]
