It is happening while rig is on for several days. The fuse is old style one time use.
Have you checked the wiring for faulty connections and ratings? ( ex. 12gauge+ wires for 20A) The most obvious signs are thin-looking wires in the circuit or bunch of " rat-tail" connections; if there's a problem, the wire or the connections will heat up and will " pop" your fuse. If you're not qualified to do so, call for a professional electrician to do the job. There's no other reasons for this other than faulty wiring since it's happening too often to be caused by a bad fuse, otherwise, frequent power outage. I am not expert in it. However how can a lower quality wire burn the fuse. Every time I noticed that fuse was burned badly. Why the "wire or the connection will heat up" will cause "pop the fuse". Can you please explain? Thanks a lot for your help. When the copper wire heats up (maybe you have it), the resistance increases and the current decreases. Thus, heating the wires can not lead to a blown fuse. If the fuse heats up with these wires, or the fuse socket has poor contact (which causes heating at high current), and the current is close to tripping, then the fuse may trip. You should be powered by quality power wires, to use a good fuse socket and the fuse 1.5-2 times of load. If the load is 15 A, the fuse is at least 22.5 A. |

I have one rig which keeps blowing fuse every other month. Load is around 1550 wattage(12.5A). I am using 20A socket. Two PSU together 1850 is being used in the rig. 10 cards of mixed 570 and 580.
Any suggestions?
Quick question... Are you tripping a breaker or blowing a fuse? What is your total electrical service? 100amps, 200amps? You really, really want to make sure you don't start a fire. AND right now your box is giving you warning signs. |

AND right now your box is giving you warning signs. I have a old style bussman fuse that blows off. It is 100ams with 4X15 and 2 X 20Ams. One of the 20 Ams I was using with total load of 12.5 Amps. I have reduced it to 11Amps and will possibly bring it down to under 10Amps |

Time to use a multimeter and test the flow or call a electrician. |

I will reduce the load further to below 10A this month. |

Watch the temp of your wires - use a Laser Infrared Thermometer - they are cheap on Amazon. |

do you have a kill-a-watt meter? some can show high watt and save if even when fuse blows
10 cards can pull over 2000 watts + mobo + cpu + ram etc
amd cards go into power runaway and all of them shift to full power.
I have seen this on more then one occasion. almost always with windows
if this happens and you are at 110 volts
2200/1100 = 20 amps and pop
that fuse can do 15 amps 24/7
try running 7 cards and my guess it never happens again.
Or try smos and set cards lower.
smos is better then windows with wattage runaway issues

Split the mining gear across different circuits to avoid single socket overload. Also try using a UPS to regulate the power and avoid surges which often blows the fuses

It is happening while rig is on for several days. The fuse is old style one time use.
And have you tried changing the fuse to find out if it would work out. You may have an old type electrical (which is mostly the best) but change it and try another brand may be it could help. Also don't forget to protect it from power fluctuations... For example, where I am, electricity can go off and come back at anytime risking your electricals. |

Agree with you running 7. Currently I am using EthOS and with 9 cards. Will move some of the cards to other rigs. Thanks |

Ah I see if you are in the USA then yes your wall socket is rated for 110 volts (usually).
In most other countries it is 220 to 240, so your fuse is probably correctly blowing because you're overloading it if you have a nine card rig.

Agree with this the fuse might be overloaded that is why it always blowing. The solution you should do if you want to fix this issue replace a new and better fuse with higher wattage because if you put a fuse which is low wattage limit than the rigs required it will always blow so upgrade your fuse for higher wattage limit. |
