Good day fellow miners,
The roof started leaking, which led to these unpleasant results  Cry

Damn, looks painful. Did everything became scraps or maybe in some just power supplies blew up and did not damage everything?

Back when i was mining i was using outlet sockets which had in built switch to cut the power off if something went out of ordinary, shorts, surges, etc. :|

Woopsie, im sorry for your loss and I hope you recover soon from that, also hiring a professional electrician doesnt cost that much in order to prevent things like this

I hope you are already recovering your losses.
For the future, you have a free space on top that you can cover with a metal sheet that will insure you against water from above. It is better to do the wiring in plastic pipes, and I also see extension cords for 3 sockets, they can be used with fuses. Can you provide a photo of your electrical panel?

Nice destruction!  What happened, did rain water leak onto the PDU and fuck it up?

What model of Avalons are those?

Same here, only a few units were lost. Somehow, the circuit breaker did not work. Good lesson.

Thanks. Yes, that's what happened, unfortunately. I believe those are 851. I like the idea of series connection and the form factor they have, but they are not as stable as Antminers.

I hope you are already recovering your losses.

We had protection, but it did not work. I will send a picture of the panel later...

Thank you!

Not sure what's the definition of smart here, but there are regular cameras. No smoke detectors.

There are all sorts of "smart" devices these days, though the specific definition eludes me--I'm still not sure how the common 2007 cellphone turned into a smartphone other than the touchscreen and all the additional features.

I do have a question: mejim knew to ask if you had cameras, and you did have them.  Is that standard for mining operations, however large or small?  Are they for security in case of theft or for other reasons?  As you can probably tell, I'm not a bitcoin miner but am very interested in it nonetheless.  Also, I'm sorry this catastrophe happened to you.  Looks like one hell of an expensive loss.

Philipma1957, do you have cameras in your setup?

Philipma1957, do you have cameras in your setup?

Cameras security locks and multiple circuits. With lots of redundant breakers.

We have lost a unit or two when we had water issues.  A fire like he had would be unlikely.

God forbid as  the room Has 1600 amps of 480 volts in it broken down into 3 phase.

The Transformers are large about 4 by 4 by 4

We simply have not been able to build out as much as the power would allow.

Second spot in another building on the grounds has the gpus.

 It has 3x 30 amp 240 volt circuits and 4x 20 amp 120 circuits.
They are to 2 panels On is a 400 amp 240 volt the other is a 100 amp 120 volt.

This room has pc monitors if the gear goes down.

We had a lot of back up breaker action..


this pdu   https://www.ebay.com/itm/164735882430? is what we use a lot.

it has 4x 15 amp breakers and 1 30 amp break it goes to a independent socket that has a 30 amp breaker in a 200 amp breaker panel

so for that kind of short to happen

1) the 15 amp breaker needs to fail in the pdu
2) and then the 30 amp breaker needs to fail on the pdu
3) then the 30 amp breaker needs to fail in the 200 amp panel
4)lastly the 200 amp breaker needs to fail.


if all that fails then we lose the transformers and the pair of 800 amp 480 volt panels = big $$$


the complex of buildings is about 1 city block  and a worker lives in an apartment on site plus it is open 24/7/365

3) Never invest more than you can afford to lose

Philipma1957, do you have cameras in your setup?
I have a face recognition camera to enter the premises, then other cameras in and out the shed, so they are basically for security reasons. The main loss came from the unstable voltage levels (it is a consequence of sudden consumption drop on one of the phases). This burned some of the power supplies, so many units stopped working and needed to have their power supplies repaired.

but to be clear it is not a farm site.

it is a warehouse site for food distribution.

he has about 300k-watts for us in two rooms in separate  buildings

Oh no that's gut wrenching to see! Even though I've been out of mining for years.

It's good that you have it in an out building and I'll bet you make some noteworthy improvements upon the repair.

Wishing you much "luck" ;-)

Oh thanks!
Here are the latest mining news: things are little crazy now, Chinese people are looking for spaces around the globe to host miners in quantities of tens of thousands of machines...or else they are ready to sell them below the market value.
I was actually able to locate 30MW dispersed through different cities in the same region for about 35 cents per kwh on average... so maybe will even expand my own thing, but it is just so ridiculously expensive, I almost feel physical pain when looking at the hardware prices.

***Typo: approximately 3.5 cents per kwh

Never heard back from my Chinese friends, but looking forward to potentially establish mining operations at these cheap locations and then re-sell this equipment to somebody else, but keep a small % of all profits... this way I can put more containers and then just take care of equipment. If anyone has any suggestions, please share...
Maybe somebody is familiar with the legal side of this question, or maybe someone has marketing/pricing suggestions... This is very new to me, I mostly dealt with the technical side all this time.

As others have stated, I hope you are able to quickly recover from this and your operation ends up stronger because of it. Thanks for sharing the pictures and your cautionary tale. It’s nice to hear about all the crypto miners getting rich, but you see less of the hardship stories and I think we’ve all got our horror stories. Good luck!

Very boring situation! I hope you can recover quickly from the losses you had.
But I would like to make a suggestion, taking advantage of the fact that you will have to rebuild some things.

In this case:

Avoid using extensions!
I would suggest using technical gutters (PVC-U Trunking), something like this:


You can see more explanations here:
https://trenchltd.com/products/pvc-u-trunking.html
I don't know this brand, but it was the only one I could find with information in English.


This will help to reduce heat near the outlets and in turn reduce the risk of problems.

I would suggest using technical gutters (PVC-U Trunking), something like this:


You can see more explanations here:

I don't know this brand, but it was the only one I could find with information in English.


This will help to reduce heat near the outlets and in turn reduce the risk of problems.
