Ayuh,.... Because it's 240V, 'n not 120V,....
here ya go.I would like to have a deeper understanding of how the current is flowing. In this case, is ground wire action as neutral?
http://www.nojolt.com/Understanding_240_volt_circuits.shtmlThat's it, no neutral. Now, if you are paying attention, then you are probably wondering "If there isn't a neutral wire then how is the circuit completed?" The answer is that when one hot wire is negative, then the other is positive, so the two hot wires complete the circuit together because they are "out of phase". This is why 240 volt circuits connect to double pole breakers that are essentially two single pole breakers tied together. In the main panel, every other breaker is out of phase with the adjoining breakers. So, in essence 240 volt wiring is powered by 2 - 120 volt hot wires that are 180 degrees out of phase.
Correct, sort of.Let me restate this to make sure I understand. The difference in sine wave amplitude between ground and hot is 120V. The difference in sine wave amplitude between two out of phase hots is 240V. Is this correct?
