Electrician's Licensing Practice Exam

Is the statement true or false? NEC section 250-28A provides information on the materials that can be used for a main bonding jumper.

1. True

2. False

3. True, but only for specific installations

4. False, it focuses on grounding equipment

The correct answer is: True

The statement is true because NEC section 250.28(A) specifically addresses the requirements for main bonding jumpers, including the types of materials that can be utilized. According to this section, acceptable materials for main bonding jumpers include copper and aluminum and must meet specific criteria regarding their size and characteristics to ensure effective electrical continuity and safety. This inclusion of materials demonstrates the code's commitment to ensuring reliable grounding and bonding methods in electrical installations. It's important to recognize that the other options, which suggest that the information is false or limited in scope, do not align with the clear guidance provided in this section of the NEC. While grounding equipment is indeed addressed within the NEC, it is distinct from the specific focus on main bonding jumpers outlined in section 250.28(A).
