More backstory they are an electrician and he has installed several chargers already. They were not intoxicated during the process, least as far as I can tell for drinking 2 bud lites for an hour+ of work
There’s no difference between two 20A 120V circuit and one 40A 240V circuit. Two 12/2 vs one 10/3. Two breaker slots vs 1. Each conductor in the 240V circuit is the same volts as the hot of the 120V circuit. All fire risks and such are essentially identical.
You should not do home repair beyond your comfort zone, especially electrical. That said, there’s nothing particularly spooky going on here.
Wiring up 240V circuits with 60A fuses was literally something many British and Irish kids did before their teens before the 90s. You had to wire plugs for every new item you bought as they were sold separately. Plugs has 13A fuses, so current was more limited… Unless you wired it wrong…
The 2 main basics that you need to be safe are these: Turn off the correct breaker, and doublecheck that it is turned off with a voltmeter before you touch anything.
I got a $5,000 estimate to get mine installed. Luckily we knew a guy who only requested beer and to not clean up the drywall
Letting a guy run a 240V line from a panel that might not be able to handle it for the price of a beer? You like to live dangerously.

Second this.
I’ll fuck around a little with 120. I will NOT fuck around with 240. I had an electrician install the wiring for my induction range.

What is the problem with it?
