comment How do I run ethernet and speaker cabling in 2 story home?
These tend to not work very well at all, I would not recommend this solution.

Is normal Cat-6 rated for wet environments?

comment Circuit split within panel
It's not dangerous, but it's definitely non-standard, and it might not be to code (I'm not sure). From what little I know about audio electronics, I believe this could be causing your line interference.

comment Could bad grounding cause sparks and fire when connecting the cable box and TV?
WTF!? I'm not normally in favor of a sue-happy culture, but I think this is one of the times where contacting a lawyer is called for. Everyone makes mistakes, but this is pure negligence. For the safety of you and others, that electrician should never be allowed to wire another house again!

This may be a better question for the electronics.SE (If you ask it there, please link to it from the comments here)

comment Why is the neutral wire the same size as hot wire in a 3C cable?
"This is why a straight 240V circuit requires no neutral wire. It is a 100% balanced line-to-line circuit." - This statement is confusing. If there were a neutral wire, it wouldn't carry a current, but it's not because both legs are balanced; it's because the neutral wouldn't be connected to anything (which is why both legs are balanced...)

comment New Fan Switch Grounding Cable issues
If the breaker is popping when you connect the ground wire to ground, but not when the ground-wire isn't connected, it means there is a short to ground somewhere. It also means the breaker/ground-wire are doing their jobs, and may have just saved someone's life.

comment Live wires everywhere?
Stud finders find studs, not live wires. And they're notoriously inaccurate - it's not uncommon to have them go off in a large area, or nowhere at all.

comment What is the purpose of the “grounding” tab/wire on a 3-prong to 2-prong adapter?
@Tester101: Fair enough. I hope you didn't read that in an offending tone - I was just curious, that's all.

comment Since neutral is connected to ground how is current kept off of ground?
I answered this exact question here, though the explanation is very technical. The short answer is, there will be current through you if you touch a neutral wire while grounded, but it will be so small you will barely feel it.

comment How is the alternating current in your home a complete circuit?
"without a return path, no generator can produce electric current" - The return-path is the same as the incoming path. Please see my first link.

@Ecnerwal: The line is grounded at the transformer, and again at the panel.

comment what are the little dots on wiring diagrams?
@curiousburke Because you're splicing two wires of the same color

comment Why is my light switch leaking electricity?
@Jason I'm not sure why voltages in other boxes can't be detected, but if you (carefully) open up another box and (carefully) wave the voltage detector around near the wires, I guarantee it will go off. Which it should.

comment circuit breaker problem after removing ceiling fan
Is that the only thing you removed? What about the lightswitch? If it was the only thing, and you really didn't splice two wires together, the only thing I can think of that would cause this would be that the nuts came loose from the wires which are now touching.

comment Sump Pump Trips GFCI Receptacle. Is a single, dedicated non-GFCI receptacle safe?
Does the outlet trip when you plug anything else into it?

comment What should the voltage be on an unused neutral line in a 3-phase supply?
Use a multimeter. It could be that there's a real voltage on the line (most likely from somewhere down the line), or it could just be a small induced voltage (which is harmless but can sometimes trip non-contact voltage testers)

comment Can 22 AWG Solid Copper carry 24 VAC?
insulation does not prevent "leakage of voltage," it prevents leakage of current (into whatever the cable is touching). Voltage loss occurs due to the resistance of the wire - thicker wires lose less voltage per foot.
