comment TV Arcs with Cablebox through both Coax and HDMI
The standard outlet testers cannot tell if the neutral and ground are both hot, and the hot is neutral, perhaps especially in this case since there is no safety ground.

comment TV Arcs with Cablebox through both Coax and HDMI
I agree with @keshlam. The appliances should not connect their chassis to neutral, but they might have a high resistance path between them? I just saw another post with a similar problem where hot and neutral were swapped (and hot was connected to ground). I wonder if the GFCI has some conductance between ground and neutral....

It's possible that the neutral and hot of the outlet are swapped. One way to check is to use a non-contact voltage detector to make sure that voltage is on the hot terminal of the outlet but not the neutral. This check isn't 100% accurate, but it generally works. Also, check the voltage (AC and DC) between the shield of the COAX and the outlet's neutral terminal. They should be close to zero.

You're right. I screwed up the arithmetic.

comment Is this a refrigerator water hookup?
I agree it is somewhat dangerous, but I can't think of any other sure way, short of demolishing the wall.

comment Pre-Romex AC circuits to DC for offgrid Solar
What DC voltage you intend to use? Will you use 5 V throughout the house, or distribute a higher DC voltage, and then have a regulator in each room, or something like that? What is the "old" wire? Knob and tube, or rubber and fabric? What gauge? Could you photograph some of it?

comment Hole in the floor
It's possible that it is an intake for combustion air used by the furnace.

comment Why does half the house go out when a single breaker trips?
Could this be a split bus panel, where the one breaker DOES control many of the other circuits?

comment I have 220V cable on a 110V circuit. Should I be worried?
The voltage rating of these cables has to do with the thickness of the insulation on the outside of the cable, not the thickness of the wire itself. Pretty much all of the cables used in the USA are rated to 600 V, so they can be used for both 120 and 240 V distribution.

comment Should a neutral wire ever be connected to the neutral for the power meter?
Yes, it's likely that this is not allowed. It depends on the specifications of the circuit breaker box. Perhaps it has a label that says if "double-taps" are allowed? What's the brand and model of the breaker box? But, the actual electrical continuity is fine. You don't need any breakers or disconnects to interrupt the neutral (except in situations with electrical generators and switches....)

comment Can I use a 20 amp breaker in the situation of having 15 amp wire connected to a 20 amp main wire?
I think that sometimes it is allowed, for example with motor loads (large inrush currents), or appliance cords. Could the answer be expanded to including those sorts of applications? For hard-wired devices, can a smaller wire be used? (Though, perhaps this is a unnecessary complication since the original question asked about adding outlets). While the 14 gauge wire is in place, one could install a 15 A breaker.
