bitcoin mining and your electrical outlets

[Zich]

Most outlets are wired in series,main wires come in to one outlet,then go back up the wall & over to the next outlet.
Sometimes as many as 4 outlets on a single line.
......

I believe they are in parallel, not series.

Quite parallel, but they can be daisy-chained .. with a load at the end socket and improper contacts in-between, all sockets will go hot.

.. kind of what you see here:


One reason to do maintenance at least once a year.

Whoo, that's fire hazard 
First outlet wire will be burn in no time.

You need to remove the cover & look inside,unless the wires are "pushed" in the back of the outlet(you may need to pull the outlet out),to see if the line goes back out.

Also,most outlets are rated for 15 amps or less.You can upgrade your outlets to 20 amp models.

Standard 15amp outlet:

20amp outlet:

Not a single outlet on the planet is wired in series.... they are all wired in parallel.


OP, clean the connection between the wire and the outlet.

You are paralleling them when you are "Daisy-chaining" them.  It's paralleling not daisy-chaining for the technical term.. lol.  It's really the same thing.

HOWEVER, I highly highly higly recommend NEVER EVER EVER EVER doing what that picture shows, ever ever ever. EVER! NEVER DO THAT EVER.

If your power isn't very good, I recommend buying a UPS.  It will protect your power supply during brown outs and spikes.  Also it will keep your miner running during very short power blips.

I had two power supplies blow.. my computer would keep restarting as I get like 10-20 brown outs a day.. UPS = golden fix.  Gotta keep that power smooth!!!

Not recommended to run a lot of power of a circuit you haven't checked / wired yourself!!

I ran all my outlets in 6mm2 cable, and ran 16mm2 armoured to the 40amp RCD! If its hot / melting or alike do not keep mining!!!

I run a lot of miners out of my house, I use #10 wire for 30A, #12 wire for 20A, and #14 wire for 15A.  If you are at 80%+ load on a standard outlet you maybe see melting or yellow especially if it is a 20A circuit as I can almost guarantee you have 15A outlets.  I would go get some Heavy Duty 20A outlets and upgrade them, these are made for that kind of load and will hold up.

Hope this helps.

On miners and UPS's... Miners do NOT like yer normal PC stand-by UPS's. Been there, tried that with several different makes. Even with a miners PSU at 1/2 load every one I tried caused the miner to hang when they switch or adjusted the voltage. Reason is the relay switch transfer time which for most UPS's is spec'd at <10ms. That blip is long enough to often cause a big enough dip in the 12v output to lockup the controller.

If you are going to uses a UPS is MUST be what is called a on-line UPS. Less efficient as they are always 'on' changing AC>DC>AC but there is zero transfer time. For several of my S4's and S2's I use http://www.cyberpowersystems.com/products/ups-systems/smart-app-ups/paragon-series/ol2200rtxl2u.html Pricey? Yes. However, are rock-solid.

btw, the s2's & 4's are the only ones on UPS's. When spiked (well, dipped really) they can be (are) the most susceptible to the sd card getting munged.. S3's and s5's just hang so the majority of the farm is not on UPS's. Waayyy too expensive to do that.

Very solid point, it has to use transistors or the switching time is just WAY to long.

I needed one for my computer lol.  It kept kicking it and the miner offline so I got two, one for the comp one for the miner. It's an S3.
