Anyway customer is gonna contact suppliers and ask for new transformer
So if all this is theoretical and you're not doing anything/charging anything, how come there's a customer.
I very rarely get customers ringing me to say "Trev, I just want to know if I can run this Gigawatt machine from my 40 amp supply in a flat I own?. I'm only asking out of interest because I've been lying awake at night wondering about it"

Well not customer yet. He called only today and I went to have a look at it. That's all I've done for him.
 
I just hope to god you don't hurt someone. From what I've read it's all too likely!

You can only hurt someone if you don't wire it safely. For example adequate earthing and right size fuses to protect cable.

Or poorly made off terminations which arc and cause a fire which kills or maims people and destroys buildings.
Just as a matter of interest, how do you propose to theoretically wire this theoretical 200A machine on a theoretical 140A supply and a theoretical 800A start up current?
I'd be very interested to see your calculations.

I'll have nightmares tonight where there'll be running and screaming.
