  1. When installing underground cable in a trench, what is the minimum burial depth required for cables operating at 600V or less in a residential area per the NEC?

    Answer: 24 inches

    NEC Table 300.5 requires a minimum burial depth of 24 inches for cables rated 600V or less in residential branch circuit runs.

  2. What is the primary purpose of using a pulling lubricant when installing conductors in conduit?

    Answer: To reduce friction and prevent damage to conductor insulation

    Pulling lubricant reduces friction between the conductor insulation and conduit walls, preventing insulation damage during installation.

  3. When mounting a transformer on a utility pole, which direction should the primary bushings typically face?

    Answer: Away from the roadway for safety

    Transformer primary bushings are oriented away from roadways to protect personnel from accidental contact and reduce vandalism risk.

  4. What tool is used to crimp compression connectors onto aluminum conductors during overhead line installation?

    Answer: Hydraulic press crimper

    A hydraulic press crimper applies consistent, high compression force to properly bond compression connectors to aluminum conductors.

  5. When installing a new service entrance, where must the service entrance conductors be spliced or connected?

    Answer: They must not be spliced between the service head and the main disconnect

    NEC 230.46 prohibits splicing service entrance conductors between the service head and the service disconnect except where splicing devices listed for that purpose are used.

  6. What is the correct method for installing a dead-end insulator on a transmission line?

    Answer: Use a clevis and tongue connection through the cross-arm

    Dead-end insulators handle horizontal mechanical tension and are connected through the cross-arm using clevis and tongue hardware designed for strain loading.

  7. When installing pad-mounted switchgear, what is the required minimum working clearance in front of the equipment per NESC and OSHA standards?

    Answer: 48 inches

    Pad-mounted switchgear requires a minimum 48-inch working clearance in front of the equipment to allow safe operation and maintenance.
