Huh weird.. I musta fat fingered something cause this photo didn't attach

This is what goes in those gaping holes i cut into my panel lol


They've got serviceable filters in em... or is paper dust to fine even for that?

 

Not really that I know of. We do a very good job at sealing up electrical enclosures and cleanliness around machinery is a big priority.

 

I'm no expert but I wanna say yes it has to be

Depends on the type of filter and how often ots cleaned. Paper dust gets everywhere it seems.

 

Make sense. Definitely don't want to keep it around, lest you end up in a CSB video

Those mills are an entirely different operation than where I work. They use a lot more dangerous chemicals/processes than the paper converters like where I work. Paper dust may have been somewhat of a catalyst (a good company would do a really good job at not keeping enough of it around to even really be a catalyst) but I pretty much guarantee you it wasnt the root cause of an explosion like that.

 

Way to ruin my fun

 

This is a real threat @Blue92 deals with... myself included but he does stuff with live power WAAAYYY more frequently than I do

I believe it. One of my previous employers also refurbishes IGBT boards for wind turbines. those panels be scary

 

Dust explosions are pretty scary.

Dude, you copied me haha

 

Oof. Yea that's a populated zip code in the danger zone... the currents those wond turbines can produce are no joke

 

You wouldn't have needed to repost him if you kept up and read every comment

 

Fucking time machines!

 

So they put 20kA in a panel rated for 100 amps then arced it phase to phase?

I read that right?

 

That's how I read it.

 

Yea

 

That's for the testing and demonstrations. I met the owner of that company and talked with a bunch of the people that worked there while we were selecting them as a training provider. Talk about a badass job arcing out panels and blowing up test dummies all day.

 

Lol you are correct sir

 

That is so cool you got the inside scoop! Yea it's definitely dramatized for video purposes but it is a legitimate concern and issue specifically in MCCs where you'll have a rack of 100A disconnects all feeding from the same bus bar that has a supply rating of 20kA
