The 240V mains in your house is one phase of the three phase supply.

The three phase is 410V.

These voltages are the 'average voltage', called RMS voltage (root mean square).

If you google it, you will find a much better explanation than I can give here.

Don't you only get 415v if you use phase A and B or phase-to-phase? Phase to neutral is 230v in NZ (single phase).

I definitely think that David Rieben and that Danyk guy are the ones who have made the biggest arcs ever.

Although it is definitely not home-made, I think this is the most ridiculously powerful "Arc Machine" I've seen:



I translated the description, and it says something about a transformer cascade. Whatever it is, it's scary.

First person arcing :) 80kVA from wall, no resonant cheating :p 12 BIG deshunted and unballasted mots in 3phase stack and rectified output. 30seconds of arcing and mots were smoking hot :)
