    Decay usually starts at pin holes on a crossarm. Pin holes are small openings or punctures in the wood that can allow moisture to penetrate. Moisture is a common cause of decay in wood, as it creates a favorable environment for fungi and bacteria to thrive. Pin holes provide an entry point for moisture, which can then lead to the deterioration of the wood over time. Therefore, pin holes are the likely starting point for decay on a crossarm.

    The first connectione you make in applying a ground set is the 

    • Ground

    • Phase closest to you

    Correct Answer
    A. Ground
    Explanation
    The correct answer is "Ground." In the context of the question, it suggests that when applying a ground set, the initial connection or reference point made is with the ground. Grounding is a fundamental concept in electrical systems, where a connection to the earth is established for safety and to maintain a reference voltage level. Therefore, the first connection made in applying a ground set is to the ground itself.

    What two connector types do we use when splicing energized conductors

    • Compression and automatic

    • Split-bolt and automatic

    Correct Answer
    A. Compression and automatic
    Explanation
    Compression and automatic connectors are used when splicing energized conductors. Compression connectors provide a secure and reliable connection by compressing the conductor and creating a tight seal. They are commonly used in high voltage applications. Automatic connectors, also known as crimp connectors, use a crimping tool to squeeze the connector onto the conductor, creating a strong and durable connection. These connectors are often used in low voltage applications. Both types of connectors ensure safe and efficient splicing of energized conductors.

    On energized conductors, we keep the tie wires short when removing them from the insulator because this

    • Prevents the tie wire from contacting other phases

    • Prevents the tie wire from contacting other insulators

    Correct Answer
    A. Prevents the tie wire from contacting other phases
    Explanation
    Keeping the tie wires short when removing them from the insulator on energized conductors prevents the tie wire from contacting other phases. This is important because contact between tie wires and other phases can cause short circuits or electrical faults, leading to potential damage to the electrical system or even injury to personnel. By keeping the tie wires short, the risk of accidental contact with other phases is minimized, ensuring the safe and efficient operation of the electrical conductors.

    The act of tying a tagline to each outside conductor with a bowline know and pulling the conductors out of the work area we call

    • Tagging out

    • Tying off

    Correct Answer
    A. Tagging out
    Explanation
    The act of tying a tagline to each outside conductor with a bowline knot and pulling the conductors out of the work area is commonly referred to as "tagging out". This practice ensures that the conductors are safely secured and removed from the work area, preventing any potential accidents or interference with ongoing work. Tying off, on the other hand, generally refers to securing oneself with a safety harness or rope while working at heights.
