OK, but you brought it up
you implied I was involved in it, whatever it is, but it doesn't sound good based on your avoidance
Besoeker was just joking that in some countries sex workers are regulated and licensed rather than outlawed.

So a "professional girl" might well be licensed. But not to do elevator work. (Quickies?)

Your words iirc.

I did not. Since you did not specify what profession that afforded the opportunity a bit of light hearted banter as the Au Excavator correctly determined.

Back to the opening post....A UPS is not a feasible solution.
Perhaps you'd care to address thaat point.

You guys need to go SI. It's so much simpler and you'd be in tune with the rest of the world...........:D

I started in the trade in 1974, I’m still working on feet and inches. It didn’t help with the plants having been built in the 1030’s so everything was imperial measurements.

Progress did catch up with me. I now have to change gear for SI measurements.

Yes, I said I was a licensed professional
in response you said they license them in the 'pink trade'
see the connection?
me: licensed professional, in response to levators
you: pink trade, nothing to do with elevators

And equally clearly a licensed professional electrician is not a licensed professional elevator technician.
In some states a licensed PE can work in any engineering specialties they choose to risk.

Licensed engineer, passed the test twice: power and controls
as you stated some states are discipline specific
only practice in the test area you passed/licensed in
not 'risk', but feel comeptent thru education and/or experience
there is always risk involved
Try getting E&O coverage without documenting competency
Try getting period for a reasonable sum lol

licensed elevator inspector & technician
among others like class A water and class A waste water system operator

I know this is somewhat off topic so mods, be kind.
Tony, I predate you by quite a few years.
I grew up with Imperial units. Yards, feet inches, miles, furlongs, chains, rods......so many units for length/distance. SI has one.

What has this got to do with the original topic? Well the mention of HP and your calc to get torque in Imperial units. And the conversion factors involved.
For SI it reduces to P=Tw.
