Power Cables and Wall Sockets


Without knowing for certain, it seems to me that power cables can only be as good as the in-home wiring coming to the wall socket. Is it possible that those who use expensive cables have improved the wiring to the socket? Or is the power from most wall sockets normally excellent, but is limited by conventional power cables?

That's not likely. Dimming lights suggest voltage drop, best cured with a dedicated line.

 

That is highly unlikely. That’s because determining the proper wire gauge for a circuit includes considering more than just the amperage. Under the NEC, which sets the minimum requirements for electrical installs, you also have to calculate the length of the run and whether the cable is enclosed in conduit. I’m not calling you a liar, @retiredfarmer - you probably were just given bad info. It's just a simple fact that  using a 14 ga. wire on a 15A line is not by itself a guarantee of safety. Consider that the purpose of the breaker is to protect the wire in the wall.
