    I have a 120/240 single phase stacked washer dryer set. I have a 120/208 or a 139/240 single phase source.
    I am concerned that the 120/208 vac source will do well for the 120 vac burden. But the two sine waves on the 208 vac source will over current and under voltage the burden. I am also concerned that the 139/240 vac
    source will over power the 120 burden and over current the 240 burden. My other concerns are the dual frequency on a burden meant for single frequency timers. Any thoughts about what will be the better source and what will happen when i hook it up?

    What country are you in?
    What are the "two sine waves" you mention?

    The equipment is meant for singe phase house voltage. I only have three phase 120/208 or 139/240 wye. I am hoping not buy a new transformer.

    Between two phases and from phase to star (wye) point is single phase.
    when you say 'or' do you mean you have both or a choice of one or the other?
    The problem may come when setting up the grounded neutrals, if two transformers are used.
