With 3 phase:
- 415 between each of the 3 live phases
- 240 between neutral & the 3 live phases
(To visualise: draw a circle of radius 12 cm, mark off dots on circle at
 120 degrees. measure between dots: 20.75cm, Neutral is compass hole in paper )

PS UK/Britain was nominal 240V, but EU inc UK is now nominal 230V +10%/-6%
