230V or 240V?

[whazza22]

I quite often hear people referring to the mains voltage as 230V but also 240V.

What do the 17th edition regs class it as?

Thanks

although i have rarely seen it as low as 230

230v single phase and 400v 3 phase

It officially 'changed' from 240v to 230v (about 10 yrs ago I think) to bring our supply in line with the EU. I'm pretty sure nothing actually changed....just that it is now referred to as 230v.

The 17th ed bases all calculations on a Uo of 230.

it's still 240 but to comply with johnny foreigner, i.e. brussels sprouts beuro rats, the IEE changed the tolerance from +/- 6% to +10%,-6% to shut em up. not sure of exact figures but that's about it. it's 240, but we have to call it 230. all be ok when we all speak german or french.

Didnt the tolerance change again to + and - 10% , not 100 % but its in the back of my mind it did

I remember my college teacher telling me everything runs at 240V untill the transformer breaks Down and they change it for a transformer that runs 230V and everything will eventually change too 230V its just waiting for a reason too change.

I personally always slip up when talking and still say 240.
