You can measure the size at the outlet. That’s not 100%, but there normally shouldn’t be any change in wire size after the panel. You can also look at it in the panel at the breaker, if you're comfortable removing the panel cover. All the wires will be exposed, including the main service wires. Act accordingly.
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?

@builder3 rereading your post I'm not sure we disagree. All the homes I've seen in CA have 14 gauge wire for 15 amp outlets. I just installed a new circuit for my stereo using 10 awg. The old one was 14 ga/15a. I've never come across a 12 gauge wire for 15 amp service but you can do it. In my home, all the 12 gauge circuits have a 20 amp breaker. I know because I replaced my breaker panel and breakers. --Jerry
Jerry, I agree. My reply was meant for Artemus who said he hadn't seen 14 gauge used for outlets. I did an awful job of trying to quote his post. And yes, you can use 12 gauge with a 15A breaker, but it's pointless. Take care, |
