When metal parts are required to be electrically connected, a(n) ____ is installed, thereby guaranteeing the required electrical conductivity.
A) suitable ground (equipment ground)
B) main bonding jumper
C) appliance branch
D) reliable conductor (bonding jumper)

Question

Quizplus · Accepted Answer

A reliable conductor, also known as a bonding jumper, is designed to provide the necessary electrical conductivity between metal parts to ensure safety and proper grounding. It is commonly used in electrical installations to bond and ground electrical equipment and metal structures. Option A, suitable ground (equipment ground), refers to the grounding system of an electrical installation and is not specific to connecting metal parts. Option B, main bonding jumper, is used to connect the grounded conductor (neutral) to the equipment grounding conductor in a service or separately derived system. Option C, appliance branch, is a term used in electrical code to describe the circuit feeding an individual appliance, and is not specific to metal parts connection.
