Question
I have a  5kw generator with a 20A/240 outlet and a 30A/120v outlet. Can I feed a 240v feeder panel with a leg from each side of the 240V plug  and then figure a way to include the feed from the 120v plug to one leg to get full capacity from the generator to the panel. What would be the best means to determine which leg gets the additional feed from the 120v branch(assuming there is no phase difference)

Bruce    I see what you want to do  I have no data on your generator but most likely you are trying to do something that is not needed as far as capacity     the 120 volt at 30 amps is not an individual winding,  you have X KW out of the unit period,     unless it is some special model    I would just use the 220 and you should get all the gen will put out  without trying to phase in the lower voltage tap      make sense?

Its kinda like those who think they save money by using 220 versus 110      it dont matter   volts x amps    lower the volts   raise the amps    raise the volts lower the amps  but in the end the POWER is the same     maybe I am not understanding exactly what you are wanting  you can find my personal email at the end of this reply   use it if you need to  but I think the wise thing to do is to just use the 220 and that should give you the total kw of the gen set  if not send me the model and brand   and let me look it over    but you should be good without trying to parallel a winding that is just a tap   not another complete winding          let me know

 Rating(1-10) Knowledgeability = 10 Clarity of Response = 10 Politeness = 10 Comment Thank you for the quick response, After writing the question I pretty much came to the same conclusion. You are absolutely correct in the Ohm's law equivalence. Sometimes I need to ask the dumb question before seeing the obvious. Thanks again for the kind response !

Electrical and mechanical repairs, trouble shooting including, vibration and balance issues. About.com provides this service, and the huge costs to provide help on about any subject. They provide the servers, the people to vet the experts, costs that would be the same as operating a good sized business, They should be appreciated for what they do, the huge costs and the great help they provide for free, Electric motor questions, can be answered here but there is a dedicated category that has other experts to help and add to a solution. Other common questions, are noises in the walls, breakers tripping, devices not starting or shutting down for no apparent reason, smoke alarms buzzing, thermostat change outs, or sizing wire or needing information for a new project, but anything can be resolved, anything, with enough effort and patience, DIY, with electrical is possible, but in most cases the use of a simple ohm meter or volt meter is needed, they can be purchased at any hardware store for a few bucks. If you have smoke, or smell smoke, don't be writing me, call 911 the Fire Department has no problem looking for smoke smells, better then spraying water on a blazing fire. DO NOT GET CAUGHT INVESTIGATING AND TRAPPED IN A BASEMENT LOOKING FOR A BLOWER FAILING< As to the tip jar, it is up to you, it is appreciated, every expert spends out of pocket that I know, we spend on IP time, computer wear, printing documents, books, and of course our time, but if we prevent a \$400 service call, we did well,
