180 degrees 2 phase supply in Norfolk

Stephen Biddle over 4 years ago

Hi

A few years ago I visited a house in rural Norfolk which had 2 phases run off a centre tapped transformer. I raised it on the forum at the time, but I can't remember now the answers. Does anyone know anything about it and the pros and cons?

Regards

We have this down in the more rural parts in my area of South Wales also.

Mike is right, strictly speaking normal 400V equipment is operating above its design voltage, and, if you ask the equipment manufacturers they will confirm if it is OK for 460/480 V.

Some is some isn't.

Most of the big brand OEM's do have equipment suitable for this system, though the wholesaler may not stock it, or in some cases even know it exists.
