Yamaha 3000 iSEB using 30 amp and 15 amp at same time

Hi,

Does anyone know if it is safe to use the 30 amp outlet and one of the 15 amp outlets at the same time?

Incidentally the cost before tax was $2480.00

  • I've had the non boost model for 9 yrs now and have done that many times. If you do get a overload light just shut it down for a few seconds and restart after turning a heavy draw item off.
  • If it works like the Honda, you can use all the receptacles at the same time as long as the total load does not exceed the gen's rating, or an individual receptacle's rating. For a 20a load I use the "30a" (23.3) receptacle instead of one of the 15s.

    I have an adapter that goes from the shore power cord 30 to the gen's twistlock 30.

    You have to juggle receptacles for what will pop who's breaker, between the ones on the gen and the ones in the rig. Soon discover what you can get away with! :( (as when I had my several Vector chargers all going at once--where to plug them in? )
