Extra warmth for the winter

3 Phase World Wide Web, NICE!!!

DON'T TURN IT OFF FOR 277 MORE MINUTES PLEASE.

If what they say is in any way close to the truth then that distribution board is way under spec.
arthurvanhoudt
My guess is that it’s not only internet that’s down.
JAPONfan
I've seen enough "naaah, this is enough" to know internet don't do that.

TOO MANY BITS CLOGGED THE PIPES
ScottHitz
No. It’s clearly because you guys raised the roof. It wasn’t done by the sun or electrical wire.
Juttypants
You see, it's a series of tubes...

Is it just me, or did someone decide to swap the blue phase and red phase on either side of that 3-phase breaker?
Defecakes
Thats not uncommon. If that breaker is used for internet, they’re likely separating it into 3 sets of 120v. Phasing for 3 phase equipment is usually heavy machinery, and the phasing only matters because it would cause the machinery to operate in the opposite direction of its intended purpose. Doesn’t damage the machine tho. They probably just swapped the phases at this breaker instead of the breaker at the main panel.
PwnageHobo
Yeah, swapping 2 phases causes 3-phase motors to run backwards, but red phase to red phase should be 0V. It's just confusing to go swapping colours like that
Defecakes
Yeah, In this particular case, they probably just split it into 3 sets of 120v in which case they probably just didn’t care to match up the colors. lol

As a fibre engineer, what? No.
skipweasel
That's almost always from not being tightened correctly at installation.

No read damnit, our building's internet usage nearly burned the building down
Defecakes
Looks like corrosion from moisture. The pipe right above the breaker has corrosion on it, so water was probably dripping onto the breaker
olgreenteeth365
you can even see the calcium trail the moisture left.

Yikes, that is nasty!

We get nasty stuff.

I don't know what to look at for lack of red markings!

I got you bud. Here's one. I hope it helps
baldbear
Thank you kind internet stranger!

Those look like electrical breakers. Probably involved with providing power to the internet of the building, but not the internet itself. Low voltage like internet can’t cause fires. It looks more like there is moisture that got onto the breaker and caused the breaker to catch fire. Looks like there’s corrosion on one of the pipes right above the breaker. I would look into how the moisture is getting in.

"Low voltage like internet can’t cause fires." - I can only hope you never get the chance to change that opinion. I can cause a fire with a 9v battery (for sure, tried it) or a small pack (IIRC 4) of 1.2 V NiCd batteries (fortunately the insulation of the cable was the only thing sufficiently flammable around). And I'm pretty sure I can convince a single 3.4 V LiIon cell, too - I have one of those for welding battery contacts, but have too much respect of Li cells to try them as fire starters.
Defecakes
That’s why I specified “like internet.” Yes, stuff like batteries can cause fires, but you’d have to either be trying to cause a fire with it, or you’d have to be negligent about where your stored that batteries, or a faulty battery. These are not batteries. I’m an electrician, and code for internet is much less strict because there’s no chance of fire is the wire is damaged.
atomicassailant
the official explanation from IT is that our internet usage is too heavy so it overloaded our circuit breaker.
ikron8211
IT are clearly not electricians.
drduffer
No. Just no.
Defecakes
Maybe a combination then. Usually overloading a breaker just results in that breaker tripping. If it burned, then the breaker was probably faulty because of the moisture that got onto it. That’s definitely corrosion from moisture on the pipe that’s right above the breaker that burned out.
Defecakes
Either way, I would also look into the moisture
atomicassailant
that and it's not my job, so I can't do much when other people installed the connection points and the circuit breaker.
atomicassailant
for context, this is in Southeast Asia and even in the least humid time of year... it's going to still be like 100% humidity.
Defecakes
Well that’s definitely something to consider. But other pipes don’t seem to have the same level of corrosion, so maybe there’s something more going on with the one that’s right above the breaker. I understand you specifically may not be able to do anything about it. Just giving my 2 cents incase it helps
