    Home audio question

    Curt, The possiblility of damage is slight but it's possible, especially if one of the kids turns on both of the Y'd outputs at the same time. Safer is to use an A/B switch that isolates the two. You would have an additional button to push then. Switches like this are available at Radio Shack...

    voltage variation tolerances

We have one of their...

    Real world European 3 phase power

    I'm designing a 3-phase medical device for use in both the USA and in the EU. Normally it will be installed in hospitals and small clinics, some doctors offices. What is the range of voltage which I should specify for the incoming power? Is 360 VAC- 380 VAC good enough?
