I want to mine on my Oven' NEMA 14-50r

[VirosaGITS]

I got the plug, still waiting on the PDU/Strip bars.

@phil
Did you end up finding anything interesting on the 40A PDU?
http://www.ebay.ca/itm/401071409648

runs over 300 new.  Amazing but every search I have done does not turn a manual up.

I do not know if it is fused>  Would be nice if it was.

I was wondering if i just didnt know how to go about it. I paid 55$ for it tho so. Hmm. I'll guess i'll try to search harder. Maybe someone else knows a better way to get the data...

Edit; Actually dug through HP pdf list and found the manual i think;
http://www8.hp.com/h20195/v2/GetPDF.aspx/c04123438.pdf

It says it has overload protection per load group. Is that what we want, and its per 15A outlet? Kinda sound like it just prevent each outlet of running more than 15A?

yeah but surges are less important then you think running this gear.

you are running s-7's correct?

And S5's and PCs/GPU rigs and AMTubes and A6. My farm setup is rather a patchwork of whatever i found best to buy at the moment. Right now i'm onlining GPU's since SHA256 is not doing all that great.

so you have a complex  net work mining.

 Now I have some understanding.  I actually think it is not surges causing issue.  give me a minute to find what I what.

all of the above are a line conditioner first  and attempt to keep you close to 230volts.

the surge protection they do is secondary.


you are more likely going down to 205 and up to 250   volts and these will stop that.

surge issues are when you go up to 330 volts --------- not your problem.

Okay thanks, those are a bit expensive and i'm moving soon, maybe i wont have any issues there. I bookmarked them and i'll test once there to see if i get voltage problems.

I'd also like to be mostly protected in case of a real surge, like a lightning storm or some such, i'm guessing the appartment will have its grid protected already but, anything cheap i can add to be a bit safer?

[westom]

They do not.  Anyone can read its spec numbers.  Those do no surge protection until voltage well exceeds 500 volts.  They do not claim to protect from surges that typically cause damage.  For example, a hundreds of joules surge is routinely converted by a computer's power supply into rock stable, low DC voltages to safely power its semiconductors. Where is a threat?

Surges that are a concern are hundreds of thousands of joules. That protection (rated at 1200 joules) means it can only absorb 400 joules and never more than 800.  Near zero joules.  Protection from surges (that can overwhelm protection inside any appliance) is by something completely different and called a surge protector.

Anyone can read spec numbers.  It claims to correct voltages that are not problematic.  Computers (like all electronics) are perfectly happy even when incandescent bulbs dim to 50% intensity.  How often is your voltage dropping that low?  Never?  If voltage is dropping that low, then a power conditioner must be installed on at risk appliances - furnace, refrigerator, dish washer, air conditioner, etc.

Today i received the PDU. I overbought the power strips, i though it was 1 strip per purchase, but they come by two and each has 1 plug, so i only needed 2 pack of 2, i got 4. But considering they were 20CAD per pack of 2, its not a big deal. I guess i'll have what i need if i buy another PDU.

I opened up the Hubbel twist lock 50A. Its 3 wire. Green, Black, White. I'm guessing this is the old code, which means the White should be Red? Thus. Those are my two 120V ungrounded (White and Black). And Green is Ground?

So if i understand correctly. The White wire (120V) should go in the Red connector (120V). The Black (120V) in the Black (120V). The Green in the Green (G). And new Plug's 4th pin, the White pin, which is Neutral can be ignored.

Green is ground = correct

Black in the black = correct

White in the red = correct

Ignore 4th pin  = correct

This  is sound mechanically
But most likely not code , not sure since you are a different country.

Should work just add gear slowly.
And remember if it is overload bad things can happen.

Try to figure out your power draw of all miners combined and keep under 32 amps

For the first week at least.

32 amps is about 7600 watts

Yeah, thanks. It should be okay. Also while reading it kinda seem to say like they say for industrial PDU, it can handle its 40A rated load 24/7? I can't because its on a 40A breaker but what if it was on a 50A breaker?

Lets say all wire up to the pdu is good for 50 amp

I think that pdu could do close to 40 amps.

I say do the 32amps because you mentioned weird power issues in your place.

that pdu has 4x  15 amp sockets 

so derate to 12 amps  that is 4 x 12 = 48 .   no way I would do that long term. 

but I think you could do 33amps safe  say 11 amps on 3 of the sockets. or maybe 36 amps which is 9 amps per socket.

I am always going to err on the short side of what you can do.\\

my pdus have 8 plugs and are 30 amp pdus.

they have 2x 20 amp slow blo fuses.

I know I can do 17 amps  on each fuse which is 34 amps  the fuses do not blow in the pdu but my wall fuse is a 30 amp and that trips after an hour or 2 at 34 amps.  which is fir sure an overload.

MY fear is the wire in the stove plug socket is not code so I am pushing numbers like 32amps

Alright thank you, very much. I could check the wires, i live in a apartment owned by big corps that build their own building so i'm pretty sure they are code. Everything need to be inspected for them to keep their license, etc etc. Also i checked the cable thats come into my electric panel and they seem pretty damn big and able of doing 125A+ But i digress. I plan on respecting 32A anyways.

For plugging the 3 wire in the 4 wire plug, to be code i think i just need to label the white wire with red or black tape or marker, so that it is clear i am using it as an ungrounded conductor.

I was gonna have someone else do this but it seem so simple i ordered a set of Hex key on Amazon and should receive it early next week. So if by the time i receive the key, Mr X doesnt get back to me, i should be just fine doing this on my own anyways.

And yeah i dont plan on going crazy slapping 8kW on this thing overnight or ever.

Just gotta figure out a way to accurately measure electricity usage. I'd know how to do it with a multi meter but there's no way i can touch the pins of these 240v cables while they're plugged in, like you could with 120v.

Once you do get a miner plugged into it please share  a picture.  I would love to see how it comes out.

Hopefully, it won't be a picture of a Bonfire. I'll probably start plugging the AMTubes and if everything goes well i'll take a pic and think of what to add next. I'm guessing the GPUs rigs would be a good pic since they would be quiet in the kitchen. But then again the S5's are already running from outside the sound proof box.

Then after that i'll have to think about how to find someone that can add an outlet in the bedroom where i'm moving to soon. Since i'd rather not do it myself. But i suspect adding an outlet count as "Modifying" an apartment?

With it being an apartment I don't think you will get away with modifying it that much.  But each lease is so different really depends on yours, when I rented I never had much freedom as far as changing big things.  Also depending where you live there is also some ordinances that you have to have certain certifications or bonded, etc.  So kinda a mix of a few things.

Hopefully you luck out and can modify it some.  My last one I was not even allowed to change door knob when one broke, I had call the apartment complex... and they took care of it.  Luckily no longer renting so lot easier.

I reckon, i'd rather live at my own place now. But anyways, as per the lease rules, i have to ask before doing any modification. But what if i do it anyways? Sound like the worst that could happen is i get evicted if they somehow find out?

Because i could set this all up in the kitchen using the Oven's plug, but that sound a bit silly.

Depends on your apartment and lease.   Some of my student apartment's were with big companies and listed fees right out and they were VERY expensive.  They had the right to walk through any time with a weeks notice.   And it was far worse then getting kicked out.  It was getting kicked out and they can still follow you with the bills/fines.  Even charge you for time you did not stay there.

I would take a hard look at lease as it varies greatly.  But the owner/apartment complex has right to walk through in most leases the details vary.  But that is when most violations are caught.  Also at time of leaving apartment complex.... the last apartment I had I went through and cleaned it where it almost spotless.  I still even owed some after I think it was like 100 dollars or so of fees they said they cleaned.  Some friends there owed closer to the thousand mark.

I think you will find it veriest greatly by apartment complex.  If you ask people in the one you are planning to go to is best way to find out.  On my last lease I knew at end they dinged you with fines.   Glad to be out of apartments anymore.

Wow, the forum lost the posts i was typing. Geh.

Well anyways, i was on about how here they can't do anything thats not in the rules set by the Régie du Logement and how i'd need to ask a lawyer or in a forum dedicated to this to really know.

Where i'm going its 100% rules as per the code, its going to be government owned. The only things added is X amount of animals, price for using A/C in summer and need permission to do modifications.

And i dont see anything in the régie du logement about fines or penalties if you break lease rules. You're expected to return the apartment the way you received it and if you break a rule, the only thing that can happen is an order from the Régie to abide by.

So if you break a rule i think you'll be forced to "unmod" it at your expense.

Worse case scenario, if i have to pay 1k of fine, i think it would still be worth it and i kind of doubt they would notice the additional breaker in the electric panel if they came in for checking the alarm or whatever.

If it happens i'm willing to suffer the consequence. I just want to get this done without causing a fire or some such.

[philipma1957]

Well remember you are in a different country then I am in and notlist3d is also in the USA like I am.

HerbPean, Finksy and  valkir are all good guys and they are from Canada  maybe they would know a bit more about apartment rules.

I think valkir has an apartment in Montreal. He may be the guy to ask.

Hehe. Honestly Valkir is the one that put this idea in my mind. He has some pretty good pragmatic ideas. He first recommended turning the electric heating already in place into mining potentials though, since its pretty easy to convert and un convert when you're done.

But maybe one of those could comment. I don't really feel like bothering any of them with a PM. I'll IM Valkir though, maybe he'd be interested in giving an eye to this project.

And for the project's progress, i'm now waiting for said person to come by in a bit, i'm glad he pulled through, so it should be even safer to do now, considering he makes a living out of building circuits, so to speak.

Hey guys!

I did use my oven plug to run some miners.
I ordered this http://www.amazon.ca/gp/product/B00BHGXYRC?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00

Pretty good but Im a little bit sad since it give you 2x 120v plugs. I though it will be 240v but the cable seems to convert it to 120v.

You could also build one yourself for almost nothing.

Just get a NEMA 14-50 male plug, and 1 or 2 nema 15-5r + some good cable. (12gauge minimum in my opinion)

Let me know if it work 

Im changing place soon so if you want my cable I could ship it to you.
