(Of course real world systems may see a minor variation in phase voltages but its very minor). In a phase converter system, DO NOT MAKE THE MISTAKE of hooking up a wildleg to neutral connection as this voltage IS NOT (REPEAT! IS NOT) the same as say an A or B leg to neutral value. Also, your wildleg will be higher than the other two legs and this value will fluctuate as a function of loading.
Hope this background helps a bit...
dev, i`m used to three phase "pot" power and find this confusing?? are you saying that folks running a third leg generator can check voltage from the wild leg to ground and get 120 (on a 220-3ph system)?
the power that i get from pots on the pole when checked to ground is 120-120-240, not 120-120-120.
checking voltage between any two legs on "pot-power" will read 240 regardless if you include the wild leg .
please make this clear to this ol` hillbilly....tod
