Re: Victor connect to 30 A instead of 40 A
Guys,
The breaker vs. wire size tables are lifted from the NEC (National Electrical Code) recommendations for open frame DC wiring based on temperature rise in the wire. A little adjustment has been made based on short time periods instead of continuous loaded currents. Snap action breakers do not limit current. That is to say, a 30 amp breaker will pass 100 amps as well as it will pass 30 amps. The only difference will be the length of time it will continue to pass that current.
