Since when?

L→L 433V L→N 250V N→E ? and unless someone comes up with the billions needed it will remain that way.

I’m just waiting for the EU to say it should be L→L 380V L→N 220V. The IET will jump on the band wagon and decree it shall be so.
Then any electrical calculations will be even more in error.

I personally think lowering the voltage "harmonizing" was a bad idea. If anything the UK standard of 250/433Y should have been adopted across the EU and Asia. 230 volts is a step back. IMO I would bet that 16, 32 and 63 amp circuits came about over the old 15, 30 and 60amperes to compensate for the more current drawn for the same wattage at the slightly lower nominal voltage.

Our N-E is 0v
Our L-E is 230v
Our Phase to Phase is 400v


Our worksites foor handtools, lighting rigs etc generally use 110v through a Tx centre tapped earth giving 55v, this is considered a safer working option to just plugging direct giving a pd 230v to earth.

I know, but my during a fault you have step touch potentials that are usually half the line neutral voltage.
