Backstabbers are off the hook

[James L]

Went went to look at a receptacle, lady said it wasn't working properly. I took one look and thought, "Gee, I wonder why"

To my fellow backstabbers, we are off the hook
At least on this one ✌

I have several receptacles in my 'collection' that are in the exact same shape or worse and none were backstabbed. The common thread, it seems, was that they were cheap receptacles. Pics available upon request.

Guessing that's where the lady had the electric heater plugged in...

Probably in winter. And a 3-outlet adapter with a computer, LED ribbon transformer, and a fan blowing on the back of the computer.

Damage to the front doesn't help matters, either

Probably in winter....

I bet there's someone running a heater right now. Some people just run cold year-round.

My wife wears a fleece jacket in the summertime. In the winter time bundled up like an Eskimo

Or a clogged screwed up vacuum...

Judging from the first picture and the corrosion on the screw and the corrosion on the copper in the second picture I would say that there was some moisture involved.

Vacuum cleaners actually draw less current when they are clogged.

 

[rambojoe]

Right...all the heat is in ze cord...

Some good ones keep on motoring- like moms royal. It is not called the beast for naught...

That's not the reason. The design of vacuum cleaners, and also hair dryers, is like a centrifugal pump. When the outlet or inlet becomes plugged, the unit is not moving any air (doing any work) and the current will go down. You can easily test this using a Kill-a-Watt meter.

Two reasons why I'm glad I don't do apartment maintenance any more...dealing with cat-sprayed outlets is one.

The other is little critters. I got out before the bedbug scourge got big again. Fleas in carpet was bad enough.

current generally goes down when clogged; power proportional to pressure and FLOW.

edit; I'll eventually learn to read thread before replying; beaten to the physics by 2 people.

But there is also a good chance the motor will overheat and trip its thermal protection. They are usually designed for airstream cooling over the motor.

That's a good point!!

 

[rambojoe]

I promise you. I understand. I got current down, dude. You might of missed a point.
Also, our fairly new bissel's cord gets hot enough for the wife shut it off.

Just curious if the Bissel is made in China. When they were made in Michigan they were the best you could buy. I never heard of a cord heating up on a vacuum like you mention.

I bought a Bissell about 3 years ago, I think it was the predecessor to the model in this picture. That cord gets hotter than a mofo

We have a Dyson with about a 20' cord. It gets fairly warm, but not so much that I'd worry about the insulation melting or anything.
