Hi diy, i was wondering: how do people get high power projects to work at home?
Im thinking of building an induction heater, and from what I can tell it is fairly straightforward. Except that I keep running into YT vids where people are pulling 15+kW in their garage, and I have no idea how they do that.

I know basic electricity, but Im not very familiar with house wiring. As far as I can tell, house circuits are limited to about 1.5 kW, and if one has, say, 4 such circuits in the house, that would be 6 kW tops.
Also, is there a way for the common man to access 240V single phase AC?

In the US you get 240 between two phases, as long as you don't earth anything you can treat the phase to phase voltage as single phase 240V.

The line that runs to your house is 240v. It's a trivially easy job to have an electrician run a 240v outlet to someplace in your garage or something.

99% if you live in America your washer and dryer have 240v like 30-50 amp outlets. It's not hard to even do this yourself with a little research.

Have fun melting shit and paying that electric blll.

Thanks anons.
So 10kW should be feasible...
>have fun melting shit and paying that electric bill
Hopefully i can melt something i can sell for profit.

Foundry fag here.

You ain't making money with electric melters.

Kwicky burner on google.

Used motor oil.

Have fun

>tfw americunts only get a single phase
>tfw americunts have it divided into two 110V legs

Your overlords truly don't want you to be self reliant at all

Hm.
The smallest main breaker I can get is 3x25A @ 230V
I put cabling in to the ground that can handle (at least) up to 3x63A.
I think it is enough. 17kW. And please remember, there is no option to have less!

Not really looking to just melt shit, but to do it controllably and cleanly. Also i live in a pretty obnoxious area and someone would report me if the oil fumes got out of hand.

My pipe dream is to make single crystals by zone melting like in the OP pic, but for now ill stick to what has been reported on youtube and say its for metalworking and forging.
