Spot the problem


Updated. Been noted on other forum, that this was a set up, not actually happened. Interesting though as to what could happen if a person did not know what they were doing in a real life situation. The appearance would be the same if a out of control electrical fire happened after Arcing or Direct Short with overheating.

wow! that's scary...is that the switch that controls the internet?!

That right there is a good reason that a quick sketch is a good idea for anyone who doesn't do that kind of work on a regular basis.

I was sitting here wondering what the switch was supposed to control...then it dawned on me...that must be the ignition switch for the wood burning heater!

So assuming he replaced an existing switch that was working properly at one point what did he do? It's hard to tell as it looks like a "normal" switch wiring job. The only thing I could think is he put the ground on the neutral post but I can't tell if the insulation was burnt off or not.

If it was new wiring, he shorted it out and had no business attempting the rewire job.

Edit: Found the original post and that's what happened - he wired the ground and hot together...

Why didn't the breaker trip? Why didn't the rest of the cable melt? Exactly what was supposed to have happened?

Someone that made a failed attempt to rouse some regulars over at another forum, by using a torch to make it appear that a fault happened.

I was going to say it looked like a torch job. I have seen switches actually on fire and they didn't look like that when the power was cut and the fire went out.

Yeah, burn patterns arent consistent with a true electrical fire.

THIS would NEVER happen in real life....trust me.

If you had a direct short like that, it would instantly arc and probably not burn for more than 30 seconds.....That is if the breaker didnt trip, which it SHOULD and more than likely would.

Even if that switch exploded it wouldn't make that much of a mess.

Isn't it a bit embarrasing that so many people actually know what the result of improper wiring actually would look like?

I actually have no idea how it should look.

It's not embarrasing... it's important to understand how to do things correctly, as well as what will happen if something is done wrong. An insurance adjuster or arson investigator would need to be able tell the difference between a true wiring fault leading to a fire and an scenario staged to appear that way.
