Longevity of 120V- vs. 240V-wired motor?
The 2hp dual-capacitor motor on my bandsaw can be wired for either 220V (draws up to 10 amps) or 110V (draws up to 20 amps). I need to install a new circuit whichever I decide (30 amp circuit for the 110V configuration). Am I correct in assuming the performance of the motor, such as amount of...- GregJ7

Circuit breakers trip on *power* overload?
Thanks all. I see my problem was imagining the resistance of a thin-wire fuse being much lower than it actually would be.- GregJ7

Circuit breakers trip on *power* overload?
I find it hard to believe that a 15 amp fuse would trip with a 20 amps through it at 1 picovolt. Thanks for the info about it being magnetically tripped.- GregJ7

Circuit breakers trip on *power* overload?
Old style electrical panels protected residential circuits with fuses which tripped (and were destroyed) when the internal wire got too hot and melted. What is it exactly that causes a modern residential circuit breaker to trip? They are rated by amps, but heat correlates to power (volts x...- GregJ7
