Video - How not to check your Oven's heater element... What could go wrong?

I knew what this one was going to be because I've seen it before. 😀

I can assure you that this scared individual received no shock nor did it throw them back 8(!) feet! :biggrin:

Adrenalin's an amazing thing, isn't it? Poor guy hasn't had sex in a while, hence the excitement. 😱

Seriously it appears these (elements) do this fairly frequently. Clean your ovens folks! All that stuff dripping down on them creates hot spots which can break down the dielectric refractory material between the inner core conductor and the outer sheath. When this happens you have a failure. Due to the high resistance of the inner core nichrome wire the draw - while higher than normal - is too low to open the typical 40-50A circuit breaker that protects electric ranges.

That said, aside from higher power switching/distribution stuff (not found in homes), this kind of electrical light show display is the most awesome thing a civilian will come across - inside their home!

Like a traffic wreck, one's curiosity makes them drawn into the action without realizing a hazardous condition is unveiling before their eyes. The best thing to do in this case is run (not walk) to your service entrance and immediately open (turn off) the circuit breaker labeled "stove" or range. If there are two breakers that are not linked together make sure BOTH of them are off.

Call for help to fix it if you don't know what you're doing. 50A 240VAC appliance is serious business. 😉

Nice to see you back Ruby!
 
Wow had no idea 240v 40a could even make that sound. :awe: Well it was probably more than 40a when that happened, just not long enough to trip the breaker. Fun stuff.

Welcome back Rubycon, we have missed your actually accurate scientific explanations of our alternalte reality theories.
 
Today we had a coffee pot short out momentarily and the (240V) arcing was impressive! Sounded like little Chinese ladyfingers going off. :biggrin:

Reminded me of this thread.

What causes the blue line to show up on video like that when recording an arc?

Some sensors will oversaturate and bloom like that. Very annoying if you shoot with high contrast as every bright object has these vertical stripes.
 
Damn!

"That's the main heating element there is making all that noise, lets see if I can..

BUUUUZZZZZZAAAAAAAAZZZZZZZZZAAAAAAAAAPAPPPPPPPP!!!!!!!!

...go change my underwear."

Fun!

I love how 9 volt batteries are designed that way. That has to be intentional. :biggrin:

The most I ever chained was 13 of em at work. I wanted to see how many it would take before I can get a shock, and that was the magic number. Then my coworker said I should lick my finger and try again so I did... woah. If the health and safety guy had walked in he would of freaked. :biggrin:

Nobody was brave enough to try it. We also burnt a 12v fan... don't mess with the IT guys. Really. :twisted:
 
I love our modern society where when people see shit melting down they think to grab a camera rather than address the problem at hand. 😀
