If there are two separate incomers (?originally 2 houses) then if they

of the voltage difference.

Some houses use three-phase power. Nobody seems to worry about that.
Does anyone take special precautions when using a UPS whose output
phase may be random relative to other unprotected mains circuits nearby?

This is a new one for me. *I* have two UPSs, one for each PC. They are
both by APC. I just plug 'em into the mains.
