Been mining away, happy as can be.... only to find a very warm outlet where nothing had been plugged into (in the next room).
"Hmmmm, what's this?" I say.

Turn off the breakers and pull it apart.... deformed plastic and a burnt neutral wire. That's weird. So I run to Lowes and replace the outlet.
Start up the miners again, and wouldn't you know it.... three slightly warm outlets in the next room (same 15amp circuit).
None of the unused outlets in my office are warm (same circuit).

"Wut?"... I've never tripped the breaker, and only using around 1200watts on this rig (on this circuit). I guess spreading rigs across circuits just isn't enough.

After talking with an electrician, I learned that heavy computer loads put strain on the neutral cable.
Time to install larger circuits with thicker wires. What a pain....

So before you burn your house down, check all your outlets on any circuit your miners sit on. The return wire could be struggling even if you're careful about the wattage you're using.
