He should have bought bitcoin instead of buying miners. Stuff like these is the reason why I don't recommend mining to anybody. Mining with a GPU rig or two is fine but when it gets "too big", then the real problems will start. Why suffer the headache with mining when you can just buy crypto and chill? This don't make one bit of sense to me.

Because you keep on adding coinzz even through a bear market. Creating cashflow/cryptoflow is never a bad thing Wink

Risk hedging. When you mine you constantly produce income, even if BTC vs USD goes down in price you still have a chance to make the money back, whereas if you just hold the coin you bear the price fluctuation risks.
In 2018-2019 nobody knew it's all gonna turn out the way it did, so the people who bought BTC at higher prices sold it all at low prices.
But some of the people who bought mining equipment were able to make the money back and had no losses.

Well now there is no going back the best you can do is to make sure it never happens again, didn't you have smoke detectors installed? It is very painful to see that, i can only imagine what you have have gone through.

It's a good joke about insurance Grin

It all started with the leaking roof, it caused a short circuit in one of the power supplies.

The damage is really extensive and heartbreaking. I'd suggest you pay close attention to the electrical wiring next time. Most fires like this usually comes from Electrical Resistance within the wires, resulting to excessive heat and fire outbreaks. From the look, this seems to be the direct result of inefficient wires. Did you use some old wire and extensions cords? Sometimes, "Do it Yourself" is not recommended in rig wiring.

Sorry for your loss and hopefully you bounce back soon, replace the damaged hardware and continue your project. And the leaking roof is another thing you need to pay attention to.

It will be cheaper if you do it by yourself, it’s really easy and if you have some electrical questions, just ask.

Bullshit. You are not talking about adding a few low power outlets to a room or opening up and working on a moderately low power (compared to commercial/industrial capacity) household breaker panel.

The knowledge required to properly and above all - SAFELY - do the wiring for 10's to several 100's of kW of power is vastly different. Even more to the point usually mining farms are a business that should carry insurance - that is not going to happen if it has not been wired by licensed professionals.

You are not good as electrician, safety it’s first place for electrician all time and no big difference of 10kW and 100kW, license is not for 10kW or 100kW of power. You can receive license for system up to 1kV(most popular) or for up to 10kV+, but it’s not a kW!

Dude, you should take a look at folks previous posts before making a comment like that.
I have been designing and building industrial power systems since the mid 1970's. I've done power for industrial lasers that pull over 1MW from what amounts to their own mini-substation.

Yes licenses are geared to working voltage but the point that really matters here is what the source can supply to a short-circuit. Just look up 'arc flash hazard' to see the huge difference between DIY wiring in a house where the SCCR *may* be as high as 10kA vs what can can happen when the building service can supply that amount as a normal load. A good example of PPE that is required when working on the high energy areas of building power can be found here. For the vidiots out there here is some very graphic video of what arc flash can do.

Point is wiring power for a large farm is NOT something that is DIY unless you know damn well what you are doing and have experience dealing with that kind of power.

Haha, if you can't read a message, why are you writing? Just look how it's done and what's kind of plug extender is used. He can just change plug extenders for a few good one and save a lot of money for future(Even just based on cable cross-sections). You don't need any license to buy plug extender, if you don't know which type you need, you can ask seller in shop and check by searchs or ask electrician. You can do it by yourself just with parameters for your equipment.
All work can be done by qualified electrician(INPUT CIRCUIT BREAKERS, JUNCTION BOX, CABLE ROUTING) and it should be done in buildings by qualified electrician, but according to you, the connection of new servers in the data center is done by an electrician, and not by administrative personnel.

I don't have a farm, but I have a few and one suddenly shorted on me. Luckily, I smelled the burning odor before any sparks or flames started.

If the system is well configured this shouldn't happen. The system should simply shut down as soon as the temperature reaches values favorable to fire.

Remember, a well-done electrical installation can cost some money, but it will save you a lot of trouble in the future, much more expensive.

Yeah, I've been wondering what I should add. Right now I just have it hooked straight into the wall on a circuit by itself. What else can I add for if a short happens, it shuts off before fire starts. I'm worried that before, had I not intervened, it would have kept supplying power until the plastic caught. I have the mining on a metal shelf away from any fuel, so nothing else will catch, but I'm still worried.

Seriously,its so badly,what arrangements,layout,and designs,to avoid fire.One thing,is check the place,give distance every circuits ,and use a silicon can protect from drops of water.Use extinction wire not overload,so that not causes FIRE, probably you can use a waterproof protect.Sometimes,unplug to avoid overheat and fire.

Unfortunately many think that the electrical installation is something simple: just run some cables and connect the socket and you're done. Then they say that they use a lot of energy, or that the system is always going down, or worse, they have problems like those reported in this topic.

A system that consumes a lot of energy must be correctly configured and installed. From the connection to the network, as the electrical panel and all types of cables and connections that are made.

Electricity is not a toy nor is it plug & play. It requires doing things correctly, to minimize problems and have good efficiency.

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.

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!

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.

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.

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?

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.

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

Impressive...

but to be clear it is not a farm site.

it is a warehouse site for food distribution.

the owner cut a long term deal for power dirt cheap and he lost an icecream company

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

Impressive...

any smart security cameras or smart smoke detector installed there?

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?

my farm has indoor tarps in case of leaks.

i have lost a few units due to roof leaks

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

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

What model of Avalons are those?

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.
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?

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

Damn, that sucks. At least not everything burned down from the looks of it. Good luck getting your farm back up!

Thank you!

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

Thank you!

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. :|

We have that, it just failed to work this time.
