5. 5. The purpose of bonding normally non-current-carrying metal parts is to:

   Carry load currentEstablish an effective ground-fault current path with low impedance so the overcurrent device operatesReduce voltage dropPrevent corrosion

6. 6. For a service with 2/0 copper service-entrance conductors, the grounding electrode conductor (copper) must be at least:

   #8#6#4#2

7. 7. A concrete-encased electrode (Ufer) consists of at least:

8. 8. When circuit conductors are upsized for voltage drop, the equipment grounding conductor must be:

   Left at table sizeIncreased proportionately with the circular-mil increase of the ungrounded conductorsDoubledBare

   TapeA steel plate at least 1/16 in thickPVC sleeveNothing

10. 10. In the same calculation, a device (switch or receptacle) counts as:

    One conductorTwo conductors, based on the largest conductor connected to itZeroThree

11. 11. Conductor splices must be:

    Anywhere convenientAccessible — in boxes, conduit bodies or fittings; never concealed behind finishes or buried in raceways (with listed exceptions like direct-buried listed splices)Soldered alwaysIn panels only

12. 12. Bonding jumpers around concentric or eccentric knockouts are required:

    NeverOn circuits over 250V to ground where the knockout rings impair the fault path (and at services generally)Only undergroundOn all lighting circuits

13. 13. Where a metal raceway containing the GEC terminates, the raceway must be:

    Plastic-bushedBonded to the GEC at both ends (a ferrous enclosure that isn't bonded chokes the conductor inductively)Isolated from the GECPainted
