Nowadays VFDs have gotten cheap enough that you can just use one of them to create 3 phases.

Or you just have 3 phase power at home (laughs in Germany).

(I actually dont right now, but my house is one of the last ones not to, and its all already prepared for it)

aside from running carney rides, and maybe a shed with a gigantic cnc or end mill - what are the reasons for pushing 3p to the domicile level? I have no doubt there must be, DE knows engineering so....

Usually, there is a 3 phase outlet in the kitchen for electric stoves

It reduces the thickness of the cables and improves the balance of loads over all 3 phases.

VFDs are definitely the way to go, that's what most enthusiasts used. When we did SirenCon over at Camp Tesumas in Wisconsin, we had a giant generator that we had to use to run the bigger sirens, especially the Cyclone 125 which has a 50 horsepower motor. It nearly killed the generator!

SirenCon

jesus I saw people in the 2023 vid w/o hearing protection - like... neat event, but do you have minimal hearing protection at all?

you can't control idiots but.. perhaps.. you could make them stand at a safe distance?

not personal criticism just damn... got my hearing loss in the army, it's not fun.

Some of them seem to think they're immune to hearing damage, which bewilders me. Smart enthusiasts have proper hearing protection.
