I am assuming he will want to build one.
The wire will be very thick. He will need a stove to use as a test load (It is adjustable). Current sensing will be more difficult.
10400 Watts.

It is a project for a grade. It should be of a resonable scale.
Maybe with a writeup on how it can be scaled up.

My emulator draws 300ma at 240V. On a housewide basis 150 ma may be good enough. that is for him to decided.
