The speed heat burners are unique and amazing. They worked by using an exceptionally high voltage (220v) at first to get them red hot FAST.. like amazingly fast and then a thermostat would reduce the voltage to 120v. They work so much better than modern burners.

Reading "an exceptionally high voltage (220v)" from a 240v country where the actual voltage is usually hovering around 255v at the outlet...

Dafuq are you low voltage lot on about?

Our electric stoves and ovens tend to be 240v too once you get into multiple burners.

well, if we're measuring dicks... :)

Ours are often even three phase since three phases are quite common in some parts of Europe. I doubt they're using 380/400V (between phases), cause they also work on 240V, so I assume they route the separate panels to separate phases so they can all draw more current at the same time.

Our three phase tends to be 120V/208V when talking about residential and small business which results in things like stoves running slightly cooler due to the lower voltage.

I think for residential they just run two phases to each apartment though.

I'm so glad to have industrial three phase power, I have a a bunch of old 'bench' (pedestal) grinders with ~1.5kw motors (2hp), all brushless on three phase power... A big old lathe, three phase drill press, a mill. If I only had a single phase I don't think I could run any of it (maybe with VFD).

Is this long video trying to explain the concept of 3 phase?

Because we have that too at 415v

What I'm getting us that they can jury rig a 240v connection if they need to, but it doesn't have an earth.

Less than 1000 volts is considered low volts in electrical terms

Depends on application.

500vdc is getting up where it's looking to bite. It'll arc if you're not careful and get too close and grab your hand then bad things are happening.

400vdc is still going to kill you if you touch it, but it isn't trying to jump off the rails and grab you.

Valve amplifiers are fantastic fun but holy shit if some of them aren't scary as shit on the inside.
