Q: In the U.S., for what type of circuits is solid wire commonly used in residential wiring?

15A and 20A circuits for 120V and 240V supply voltages — Solid wire is primarily used in the US for common residential circuits like 15A and 20A circuits with 120V and 240V supply voltages.

Q: What is a key advantage of solid wire over stranded wire in home wiring, according to the article?

It can carry more power for the same gauge at 60 Hz — Solid wire can carry more power at a frequency of 60Hz compared to stranded wire of the same gauge.

Q: Why is the flexibility of stranded wire not a significant advantage in U.S. home wiring?

The wiring is typically installed permanently behind walls, ceilings, and floors. — Because home wiring in the US is typically fixed in place, the flexibility of stranded wire is less crucial.

Q: Which of the following is a disadvantage of stranded wire when compared to solid wire, according to the article?

More difficult to splice together with wire nuts. — Stranded wire can be more complex to terminate and splice, with a higher chance of individual strands escaping terminals.

Q: What is the primary reason why solid wire is cheaper than stranded wire?

It has a simpler production process. — Solid wire is cheaper because it has a simpler production process.
