All my breakers get warm/hot to touch

24A @ 240V on a 30A breaker (single phase)

21A @ 208V on a 30A breaker (3 phase)

Both are continous load and on 80%. But they sure do get warm to hot sometimes.

Posted a pic on facebook of some miners and the a dude commented that it was a fire waiting to happen.

Does anyone have some good advice or hacks to manage all the wiring ? LAN cables are especially messy.

This just happened to me, miner was hashing at 9.5 TH/s and one of the small red LED light on the board was not lit.

 The troubleshooting sequence was

1. Unplug all sockets from PSU to S9 and replug them in making sure they are tight.
2. Try another PSU
3. Reset the S9 and re-load firmware

None of it worked. So had to create a repair ticket and sent it to Cali for repairs. The complete unit for S9 needs to be returned for warranty repairs. Bitmain also stated that it will take a week to repair.

Warranty steps were pretty straightforward.

Hopefully I will get it back soon.!

that is still within normal range.

Most of their fixed cost and suppliers must be paid in fiat, probably RMB and USD.

How would they be cashing out ?

i am able to run 4 on single phase 245V , amps range from 23.5 to 24.5 for 4x S9 14.0T

my other location runs on 3 phase 208V , amp ranges from 20 - 21.5 for 3x S9 13.5T

the 30A breakers do get quite hot.

I have an extra 10 of these, 10% off if you take them all at once since ill save shipping

The electrican actually messaged me back today and offered to do it for $6000.

I need to get more quotes

yes, panel is already in place. Just installing breakers, wiring, conduits and outlets, will ask for a breakdown

heres a pic of the space, outlets are just going to be installed right outside the small breaker box room

I need to get this done at a new location in WA. This was a quote from my first electrician. The outlets are installed within 10-15 feet from the breaker box. Electrician provides conduits, wiring, breakers and labor. I bought the outlets and outlet boxes myself

Job Description: $7,350.00 + sales tax = $8000

Provide labor and materials to install (10) dedicated 50 amp circuits to the upstairs space from the
panel to dedicated outlets. All work will be in 3/4 inch and 1/2 EMT surface mounted to the sheet
rock. Owner will provide the outlets.

has anyone done something similar at this price ? or should i continue shopping around ? $8000 seems a tad high considering parts would not even reach $500

Thanks!!

I saw this in Shenzhen today too. how much did you pay for it ?

I was in the same situation , maybe you can keep looking and can find somewhere that has a better ventilation set up

I managed to find a place that has windows and all I need to do is put huge exhaust and intake fans at the windows

The single garage door set up is pretty hard to cool well unless you start punching holes in the side wall or ceiling
