The key point folks here are getting to is that running a miner much less several requires setting up significant power circuits and is not something most folks can, much less should attempt, to do by themselves. It requires working with a licensed electrician to safely spec and install the needed circuit breakers, wiring, and sockets.

Thank you for your response...truer words. I did work with an electrician, but we got the plug wrong! Being a noob is hard, but doesn't last forever. Aside from gpu home mining for many years now, I've had s9s and s15s hosted, but now working on bringing asics home. It's a challenge!

Phil I apologize for imposing and thank you for the information. I know that seller's name from telegram! Will pursue.

I've mostly just lurked around here on and off over the years and am not well enough practiced in the culture. I blame discord where everyone is yammering at all times! Tongue

I found email the answer is no.

Let me try to explain what happens to me.

The email account you sent to is 23 years old. It gets 250 emails a day on a slow day. If I go back just to July 10 it is 27 pages back.

So you sent it on the 11th> I read it and did not want to answer it yet.

I think the price for the gear is too high.
I do not like the seller.
I did a few deals with him they always have a glitch.
They work out but always with an issue or a scare.

We all help each other voluntarily, free of charge, when we have time for it.

Could not agree more, I do feel bad for not replying to some PMs I get (despite the fact that I try and do respond to most of them), but people should understand that we have many things aside from the forum to attend to, also, it is always in everybody's best interest that all questions remain public (unless there is a very private aspect you need to hide), I don't mind answering a question sent via PM, but it would be a lot better answering it publicly so that other folks that have the same question could potentially find it in one of the search engines they use.

So, OP, if your question is not "secret" just ask here.

Hey thank you for your reply. I am absolutely willing to pay and not looking for anything free. I have a specific and personal inquiry with him or I would post here, of course. Maybe we will post here about the matter in due time.

edit - may I contact you privately about the matter at hand?

edit2 - I have sent you a message, my first one ever!

Hey I can imagine that you're crazy busy, but I would be grateful if you could have a glance at that email I sent at your earliest convenience. I'm deferring a big decision until I hear from you. Thank you so much! I hope you get your car situation straightened out to your satisfaction! And really glad nobody hurt!

Just a quick comment / suggestion.
Don't put too much pressure for Phil or others.

OMG, meltdown. I had a small meltdown incident with risers on a gpu rig. Nothing dangerous, but it was complicated and annoying to repair. Hopefully I have learned my lesson.

I didn't even consider running three rigs with two on low power, very clever!

I am very grateful for your guidance sir. Been following you for years now and also hope to get some solar power into the mix in the future.

Always remember it (mining) is kind of like a long highway trip.

Yeah you can max the car to 100-120 mph but cruising at 70mph is far more likely to not make a wreck on 1000 mile trip

Of if not in USA maxing the car at 180KPH for 1500 kilometer drive is not as safe as driving it on cruise at 110KPH

Ok, that all makes sense, thanks for looking. Too bad I can't just use an adapter. I thought the plug configuration wouldn't matter because I was going from 4 prongs to 3 prongs anyway. Learning.

adapters add 1 more set of fail points.

remember you will be doing 3200 + 1700 = 4900 watts 24/7/365

or if you run the 2 s15 on low and 1 s19

950+950+3200 = 5100 watts

those are under rated limits but close so the less connections the better off you are.

And the pdu has multiple circuit breakers inside of it for safety sake.

I have like 14 of those pdus all used from ebay

as cheap as 35 and as much as 70 depends on how hot mining profit is.

I do like them. They have help prevent burn ups.

https://bitcointalksearch.org/topic/farm-on-fire-5334851

notice a guy set up a farm with adapters to sockets not pdus. look at last photo adapters to sockets

the pdus I showed would very likely not let that happen. (95% sure of that)

Yes, that makes sense, thanks. I'll purchase the 24A PDU.

Were you able to see the pic of the plug at the shared link? Not sure if that's how I should try to post a pic?

this website is free www.imgur.com

Yes here it is:

he did a different receptacle than the pdu uses.

the pdu uses this plug

https://www.ebay.com/itm/283235260568?

and this socket

https://www.ebay.com/itm/253309669606?

you need to either replace the socket on the wall or the plug on the pdu.

I would show the electrician the ebay items and the pdu plug when it comes.

it is not that he did bad work but 240 sockets vary and it is a simple mismatch he can fix.

I like the locking plug and socket a lot not the one he did. Basically the pdus fit and they do not come loose.

The price is reasonable for the pdu, but I wonder that is says 24A on it. Is that ok?

Quote from: philipma1957 on July 01, 2021, 07:20:16 AM

give me five minutes i will link all the shit you need.

https://www.ebay.com/itm/174407469460?

that is the exact pdu you need.

yes it is derated to 24amps for safety.

24/30 = 80%

running a 30 amp circuit does not mean

30 x 240= 7200 watts

it means

24 x 240 = 5760 watts.

Which seems to be familiar.

you mentioned it in your first post.

dont know how you got the number but it is the true rating for 24/7/365 use of a 240 volt circuit.

you should have enough juice to spare on you gear.

unless you run closer to 220 volts

that would be 24 x 220 = 5280:which is still a little more than what is needed for your gear.

More or less what Phil said. The reasoning behind it is: As a rule a PDU is designed to be running 24/7/365 at full power in data centers / equipment racks. But they do not smooth out the power. The cords you are showing will work but they are more for temporary use and not for 100% power all the time.

With that being said, they will work. But with the amount of power you will be putting through them do you really want to risk damage to your equipment or an electrical fire to save a few dollars?

please show me a photo of the receptacle out he gave to you.

https://www.ebay.com/itm/174407469460?

that is the exact pdu you need.

but i do not know what receptacle he gave to you so you may need to swap the plug or the receptacle.

give a minute to find the correct power cables

https://www.ebay.com/itm/184114573116?

the pdu has four receptacles

you will use 3 of the four

you need three of those wires.

so three wires and one pdu.

I do not know those sellers.

the prices on the wires were pretty good.
the pdu price was okay.

ie if you really look hard you may find the same pdu cheaper.

but please show me the receptacle on the power outlet so i can see if the plugs match

some advise ask us before you call the power guy so we can show you proper receptacle.

the gear i linked is under 100 bucks.

not sure about plug receptacle

Ok, here is the splitter arrangement I was looking at: https://www.amazon.com/30-amp-splitter/s?k=30+amp+splitter

I am considering what else I need...a surge protector at one end and two prong converters at the other end. What do you think?

Thanks for the convo, not too many people to talk to about this stuff.

Not sure where you are located so the plugs / versions will be different but what you are looking for is a PDU.

Ok, thank you, I could not remember "pdu" and my searches weren't turning up anything useful!

I had a special line installed by an electrician: 2 pole 30 amp receptacle which has 5760 watts available.

s19 = 3250W
s15 = 1600W

So anyway, I thought I saw some forked cables around or maybe there is some kind of power strip for 30amp? Do I need a pdu? Is it meant to smooth erratic power? I think I have a good steady supply.

The normal amp outlet for most homes is 15 amps so if you have an s15 miner and planning to run two miners in one outlet it should be 2x1596W=3192w.
Then for the outlet 15x230v=3450w, this should be how much can outlet can handle.

According to some miners, the outlet shouldn't be over 80%, so the two s15 couldn't run in one outlet unless you can run the miner at low power mode. You will need to modify your home circuit and replace 30 amp wiring and breaker so that it can handle two miners in one outlet or much better consult to Electricians.

Not sure where you are located so the plugs / versions will be different but what you are looking for is a PDU.

Something like this: https://www.amazon.com/Rack-Pdu-Basic-14-4KW-208V/dp/B000FLWCLE/
or this: https://www.amazon.com/Tripp-Lite-Metered-L6-20P-PDUMH20HVL66/dp/B08SZ77TFZ/

Those models are designed to be rack mounted but you get the idea.

Due to the massive power needs of miners make sure the one you get can handle the load.

For the most part you are usually better off getting dedicated runs for each miner but if you can't if the circuit can handle it you can use PDUs.

Hello, I have a couple of s15 miners that were hosted previously. Also interested in buying an s19. Anyway, I'm wondering how to safely plug two miners into one plug. Maybe I remember some years ago a PMS was mentioned on the forum? Or maybe there is just some forked cabling?

Thanks!
