This is terrible advice and kinda dangerous as hell. You're connecting the Tesla with a 14-50 connector, to a 14-30 adaptor from a hardware store, and drawing 32 full amps. While you may not have blown out your fuses with this terrible idea, someone else watching your video might burn their house down. A 14-30 circuit is not rated to handle anything above 30 amps, and a margin of safety is always required in the event of variation and surges, following the 80/20 rule. The load can't be higher than 80% of the rated amperage. This is why a 14-50 plug requires a 60am circuit and the tesla will draw no higher than 32 amps.
