I say again Harmonics are not an issue with single phase supplies. [Linked Image]

The currents do not add up on the neutral as they can with a three phase supply.

Edit.

OK I will amend this to I have never heard of harmonics bing an issue on single phase system.

I will also point out we are not talking about switching power supplies in this thread.
