In the UK and I believe Europe I would not expect to see 3 phase brought into a household environment as this would expose the customer to line voltages (root 3 x phase voltage [line-to-neutral]). Even in office locations the power outlets are kept to a single phase per floor to prevent an inadvertent connection between two phases.
Even if your scenario existed it would depend how the neutral was wired to each outlet; if it was a common neutral ring then the chance of problems would be greater than if each phase was fed with its own neutral return from a star point.

The feeding is with three-phase and one neutral conductors. If I connect a TV and a blender in the same phase, the blender generates interference (lines) in the TV screen. If I connect the TV in one phase, and the blender in another, the TV will have interference??? The neutral conductor is the same for all (of course!)" Seems very plain, but I'd like to know... :) Thanks in advance Muriel -- ====================================================================== Muriel Bittencourt de Liz GRUCAD - Conception & Analysis of Electromagnetic Devices Group Federal University of Santa Catarina PO Box: 476 ZIP: 88040-900 - Florianópolis - SC - BRAZIL Phone: +55.48.331.9649 - Fax: +55.48.234.3790 e-mail: [email protected] ICQ#: 9089332 --------- This message is coming from the emc-pstc discussion list.
