Surge Protection Issue

[IamRune]

I have been expanding my machines and noticed that when I have 2 rigs plugged into the same surge protector it keeps tripping.  The breaker is 30A and never trips only the surge protector.  Any suggestions?

Thanks!

Your breaker is 30a, but what about your surge protector? Surge protectors have amps/watts limits too. Most common surge protectors they sell at local stores are just 15amp/1800watts.

any new generation psu have surge protection nowadays, you don't need to worry about that, at worst case you can get an UPS apc smart one that can protect your device

for a answer we need more data....how much Watt or Ampere per Rig? Are there any other consumer on the 30 A breaker?

[IamRune]

No other devices on the breaker.

Currently dual mining it's pulling 1500W.
It ran fine with 1 rig @ 1500W but it's just a single outlet so I had to use a surge protector for the extra outlet.

Could I just buy a outlet adapter that supports 2 plugins or should I change out the outlet?


Thanks

Which surge protector are you using? Most have a limit on the amount of current that can pass through.
Try switching the surge protector with a normal power strip/adapter, though ideally you may want to use different outlets.

The standard NEMA 5-15 power receptacle (https://www.google.com/imgres?imgurl=https%3A%2F%2Fshowmecables-static.scdn3.secure.raxcdn.com%2Fmedia%2Fcatalog%2Fproduct%2Fcache%2Fimage%2F700x460%2Fe9c3970ab036de70892d86c6d221abfe%2Fn%2Fe%2Fnema-5-15p-inlet.jpg&imgrefurl=https%3A%2F%2Fwww.showmecables.com%2Funiversal-cpu-power-cord-nema-5-15p-to-c13-15-amp-25-ft&docid=kRcwejuRoUU6uM&tbnid=-rGkAyCPgRH-LM%3A&vet=10ahUKEwiX_v3U0IjUAhUr9YMKHedAAHEQMwhwKAEwAQ..i&w=400&h=266&bih=558&biw=897&q=nema%205-15p&ved=0ahUKEwiX_v3U0IjUAhUr9YMKHedAAHEQMwhwKAEwAQ&iact=mrc&uact=8) cannot provide more than 15 amps.  All plugs are designed and installed to avert fire and other human safety issues.  Power strips (with or without protector parts) trip because a human has created a potential fire.

A receptacle powered by a 30 amp breaker must not be a NEMA 5-15 receptacle.  A 5-15 receptacle can only be powered by a 15 amp or 20 amp breaker.

what is the 30 amp breaker in your box   for 240 volts or 120 volts?

are you doing 110/120 or 220/240 power.

most usa home do not use 30 amp breakers for 110/120 volts.

I ask because  if you put in a 30 amp breaker in the circuit box  the wires in the wall need to be 10 or 8 gauge not 12 gauge.

Talked to an electrician and he recommended installing a 60A sub panel and installing 4 quad outlets.  I only use the surge protector for the outlets.

Any thoughts? 

Will 60A sub with 4 quad circuits be sufficient for 4+ rigs?

You don't care what others believe.  You do the arithmetic.  If one rig is 1500 watts at 120 volts, then the arithmetic is easy.   1500 divided by 120 is 12.5 amps.  That means a receptacle (you did read the previous post) rated at 15 amps can only power one 1500 watt rig.  So one rig is powered by one receptacle and one circuit breaker.

Four breakers powering four receptacles means only four rigs - no more.  Again, never leave others to do your arithmetic.  You do the simple math.  Ask how to do that math.  Ask others to confirm your calculations.  Since only you (not even your electrician) is ultimately responsible for what happens.

I only use a surge protector in my main rig that I used for browsing and trading and never bottered to use it for all my mining rigs. Most people that mine usually have a high quality PSU and it has a surge protector built-in.

I did at one time buy a bunch of cheap surge protectors and was using them for a while. There was never a surge or an outage so I can't tell if they worked or not but my issue was that the surge power bars ended up melting in certain areas.

Basically 1500 Watts or so was way too much and it caused some of the leads to run hot and start to melt. When I noticed this I disconnected all the surge protectors and never used it since and never had any issues.

There are probably better surge protectors at +$100 or so but I didn't find it wise to spend that much extra to get a mining rig up and running. Maybe I was just lucky.

1500w if on 110v --> asking for trouble, just to be safe, on 220v, any 16amp socket should run only 8amp x 220 = 1500w maximum 24/7. Cables should be always 50% more room, if a cable is 20amp then always use maximum 10amp, to have the right and safe procedure is very expensive but you will not burn your house if something happens.

to sum this up, breakers are meant to protect the wires. 50% is the safe zone because at 60-70% even if the breakers does not trip from time to time, breakers tend to be warm and get cooked/burned in long 24/7 usage


for me i pushed the wire to ~65% and increased Amp rating of my breaker (push limits only if you know what you are doing)

 - not part of the building wiring (mining dedicated wiring)
 - i know my wires, the breakers, the load

so far so good.

I like how you guys are responding to a 2017 necro post
