Main Question or Discussion Point
For US residents. If you have the above circuit breaker put in your panel phase to phase (2 pole).. and one of the phase touches neutral.. would the circuit breaker trip or not? It's rated 240 volts.. yet one pole only has 120 volts.. would that 120 volts shorting the neutral trips it?
This was written in the label above reproduced here:
Current Interrupting Rating
Max RMS/Sym Voltage
10 KA 240VAC
Type TOC 2430WLX
And what does the 10kA at 240VAC, 5kA at 415VAC mean? at 120VAC.. it could become 20kA... would this make it trip if shorting to neutral (let's say the wire inside metal enclosure accidentally touch the enclosure connected to neutral)?
I mentioned specifically neutral and not ground because in our location. We only use phase to phase to create 240 volts. All our equipments are 240 volts. We never use phase to neutral of 120 volts. Hence our neutral is made our ground. We don't have separate ground because since we don't the neutral then they make it our ground.
