on a 15kw generator,50amp 3pole/4wire 125/250volt how many circuits will i be safe with ,and no overload to gen set 120 circuits,240circuits or combo of both(3 are motor ckts )well,refrig,frez

Anyone who is really an electrician would know that sheer quantity of circuits is not relevant.

Are you sure you have a 3 phase 240 volt generator? If so
the gen can put out about 36 amps per phase at full load. You don't what to run at full load all the time so you will need to reduce that figure. The number of circuit does not
mean anything.

madeinusa-What is the primary voltage? What are the loads of the equipment you want on the generator? How many steps are there? If you want to run multiple scenarios to get an idea you may want to try a genertor sizing program such as Kohler or Onan.

To me, 3-pole/4-wire means 240/120 w/ 2 lines, a neutral, and an EGC.

I chose not to give any more info because I felt this was a DIY question.

I agree with Larry, this is a homeowner DIY'er.
