You were wrong; I wasn't.  You did say "new firmware" which, for all intents and purposes, means the "latest firmware".  You're firmware description was obviously wrong but my interpretation of your firmware description was correct.

Accepting your mistake is commendable but to drag me into it is not cool especially when my intention was to help you out sincerely.  Again, be brave and accept your mistake on your own; don't drag me into it.

You should have used receptacles and matching plugs that make plugging in 120 V device impossible.

Yep. 

Couple of ways to run the cable to outlets.  Although a 20 amp circuit with 12-2 might have 15 amp outlets, the total allowed wouldn't change.  The 15 amp outlets have a couple of ways to clamp the wire.  They could have the solid #12 looped around an outlet screw and clipped, then another length of #12 wrapped around the other screw on that side and clipped, and run to another outlet, same on the other side of the outlet.  Or they could have pre-built the circuit for the room and stripped back the #12 for 3/4" and made a loop and only attached it to one screw, not clipping the wire but tough to route if you're using holes cut in the studs before the drywall goes up.  If looped and clipped the 15 amp outlet could conceivably see more than 15 amps thru the metal on the side having the two screws.  Or, and this is more likely to cause outlet heating, the electrician ran the cables to the empty boxes, the cables cut a foot or so beyond the box.  He stripped the #12-2, both the black and white, a half inch and pressed the wire into the hole in the back of the outlet, black to the side having the gilt colored screw and white to the side having the silver colored metal screw.  Then took the cable to the next outlet and did the same to the other pair of holes on the back of the outlet.  This type of daisy-chaining, using the push in holes, likely see the solid conductor making contact with a metal tab pressing on its side and is more likely to heat.  Not sure if a standard 15 amp outlet would accept #12, hold on I'll check...nope, #12 won't fit the hole in a 15 amp outlet.

If your electrician is running a complete new circuit you may consider a 220v circuit (or two) dedicated for your mining hardware.  You can run more off a 220v circuit, plus it's a little more efficient  (which is always an upside) to run the power supplies off of 220 vs 110.  I ran 2x220v circuits to where my miners are located and it was the best thing I ever did.  If you do this, just be sure that it is recognizable as a 220v circuit.  I have orange outlets and red stickers warning of the 220v circuit so 110v equipment isn't mistakenly plugged in (although I'm the only one that uses that area of the basement).

They aren't overclocked. They are straight outta the box. My wife is an interior designer, so all my miners MUST remain in my office so as not to interfere with her masterpiece haha. Not worried, though. I've got an electrician coming out here tomorrow and he's gonna put another circuit in here and I'll be back in business. Need a pro to look at it anyway. If the wiring is crap I need to know now before something terrible happens anyway. Thank you, mindtrip, for saving my family's life LOL

you supposed to run only 3 overclocked S3 on a 15A circuit (at 110/120V). You might barely run four, but at the regular speed (not overclocked).
Six is seriously pushing it-prone to disaster. However, check you circuits-I have two close by, so just connect three miners to one and the rest to another circuit.

Thanks again, mindtrip. Yeah I'm just waiting for my guy to show up and laugh at the total sh*t nest behind my outlet covers here. We will see soon

Hey Missouri! Thanks for the input! The circuit is 15A actually. Spoke with the guru of all things electrical (my pops) and he said that the wiring  in my new house is total sh*t. **NOTE - don't assume that just because you've paid a ton for a new house that the wiring is exceptional**. Therefore, I am on the hunt for a good electrician to swing by and solve my problem for me. Adding another circuit (and possibly upgrading the current wiring) is in the cards because NOT mining is not haha. Thanks again! Cheers - \m/

I agree completely I have most circuits no more then 2000 Watts and nothing gets warm not the outlet or the breaker and have never blown a breaker and lost mining time 

Your welcome not to get into a lot of detail but usually outlets are all linked together on a circuit so if your wiring gauge is incorrect or an outlet is not wired correctly it can cause a high load at a particular point in the line in your case that hot outlet is probably in between the outlet your using and the breaker. If the wiring is old this is a concern. I personally ran new dedicated 20 AMP Circuits for all my mining locations to ensure 1> Correct gauge wire and outlets were used 2> nothing else i wasn't aware of was on that circuit 3> Peace of mind

Need to know what amp circuit the room is using.  A 15A circuit has a max of 1800 watts, but you should probably keep it under 1440 watts.  A 20A circuit has a max of 2400 watts, which is what I have, and they say to keep below 1920 watts, but I'm running a little over 2000 watts.  (80% of max for continuous load.)   You could have the wrong grade of wiring.  A lower grade wire will get hot, and could even cause a fire if not up to specifications.  For example, if wire that was rated for a 15A circuit was used with a 20A circuit.  Even with 2000 watts, my outlets are not hot to the touch, and barely warm.

Hi mate, I take your point, but I think you've done the right thing.  The asics in the S3s seem to be rather temperamental and someone posted a while back how just running without the case fitted was enough to 'x' out an asic that was distant from the inlet fan.

Thanks, mindtrip. Obvious answer to a stupid question

easy solution your overloading the circuit probably do to poor wiring in your house I would move one of those power supplies to a separate circuit right away to avoid a fire!!!

Need help here. Anyone running multiple S3s on the same circuit, and if so, what are you powering them with? I have 6 of the new batch 8 S3's, and they are all on the same circuit. Running two pairs with a Corsair CX750M each and the other two with an EVGA bronze 1300W. Thought this would work well, and they mine perfectly, but the one outlet in the room that isn't being used for anything is warm to the touch. This obviously isn't good. I was a noob before this running two overclocked S1s with one Corsair CX750M and have apparently bit off more than I can chew.

Any help from one of you vets would be highly appreciated 

A router and an internet connection is all that's needed for the S3 to run. However, you'll need to use your laptop to configure the IP address and pool information though.

Is it  possible to run the s3 with 3G ? simcard + x (simstick , router Switch, Adapter?) + netbook = ?

I have 2 s1's that after a few hours ALL the chips go to X. they are both overclocked and their hashrate stays at 200gh/s so I just leave them alone. They been like that for a few months. So I have to assume its a software glitch.

1 is at 10days 31k HW's which is extremely low. 216 rejected 6 stale.
other is 10days 114k HW 536 rejected 1 stale 
114k is very low also.
