13. Which of the following is a method for identifying a grounding terminal for connecting an equipmentgrounding conductor to a device?A. The letters EGCB. A green octagonal nutC. A red pressure wire connectorD. A green screw with a hexagon head
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?
Which of the following statements about equipment grounding conductors (EGCs) is true?A. The National Electrical Code permits the EGC to also perform as a grounding electrode conductor.B. More than one EGC must be used if multiple circuits are installed in a single raceway, cable, or cable tray.C. No current should be present in the EGC during normal operation.D. EGCs are required to be decreased in size to address voltage drop.
