Circuit Breaker plug
« on: November 26, 2018, 06:52:22 PM »

A Circuit Breaker is built into the plug.  If it trips, it unplugs it self!

Very cool, indeed. A non sequitur, but this reminds me, for some weird reason, of a cable tension failure detector I saw on a ski lift on Mount Ashland, OR last summer. At the top of the hill there is a huge, ugly chunk of concrete that serves as the tensioning weight for the main rope. Attached to it was a funky, rotting cord and plug arranged so that if the weight moved outside of a certain range the plug would unplug and, presumably, ring a bell or something down at the control panel. Somehow I don't think this lift was made in Switzerland. -F

It likely unplugs the lift motor.  Probably designed by snow skiing engineers in Lower Alabama and built by Northern South Dakotans from Hoople, SD.

That sounds like a Rube Goldberg invention!

My pressure washer has a GFCI built into it's plug. My in-wall heatpump/airco has some sort of a smart plug... with "test" and "use" buttons.

I have seen plugs that sense for leakage to ground and disconnect (different than GFCI).

[edit- I read the OM and my airco has one of those leakage plugs... apparently it's an UL thing protecting against squashed line cords. [/edit]

I keep envisioning someone "fixing" that with plumbers tape and a couple drywall screws because, "The damn plug keeps falling out!"

Years ago, one of my dad's shop buildings was in danger of collapsing -- I think it was the Romex leading into the building that was holding it up. I braced the bulding best I could. I had planned to wire the Romex with a plug and receptacle so it would unplug itself if it did collapse.

But, life got in the way, I moved away, and eventually my brother tore down the building, so my "self-unplugging disaster" never happened.
