4. Do some search about the functionality of Airport Metal Detectors. Explain your answer in a paragraph.

Assuming all terminals are rated 75°C and you have a  #10 AWG THHN/THWN conductors in a conduit and the conduit is run on the roof off a office building where the ambient temperature never rises above 30°C the largest size circuit breaker or fuse permitted to protect these wires is:?

The wording that I am running into with questions such as "The number of conductors required to be installed between three-way and four-way switches is " is confusing.  The text is not expalining this in a way that I am understanding anything other than grounding conductor, which is optional unless I am using a metal box.  So what type of "conductor" is beng discussed?
