Zorluk: KolayElectrical Hand Tools

When servicing an industrial control cabinet, a technician must safely remove a cylindrical cartridge fuse from its spring mounting clips. Which hand tool is specifically manufactured from non-conductive insulating material to perform this task without creating an electrical shock hazard?

  1. A
    Lineman's side-cutting pliers
  2. Fuse pullerCevap
  3. C
    Long-nose steel pliers
  4. D
    Slip-joint utility pliers

Cevap

Fuse puller
A fuse puller is manufactured from high-dielectric insulating materials such as vulcanized fiber or molded nylon, featuring specially contoured jaws that clamp securely onto cylindrical cartridge fuses without conducting electricity.

Adım Adım Çözüm

1
Identify the electrical safety requirement for removing cartridge fuses from mounting clips.
Cartridge fuses reside in spring tension clips that may remain energized; using metal hand tools creates a direct shock and phase-to-ground fault hazard.
Standard metal hand tools conduct electric current directly to the technician's hands.
2
Select the dedicated hand tool constructed from dielectric, non-conductive material.
A fuse puller provides mechanical leverage and notched jaws to firmly grip cylindrical fuses while insulating the operator completely from electrical potential.
Dedicated fuse pullers ensure compliance with safety protocols by preventing current flow through the user.

Anahtar Kavram

Non-conductive electrical hand tools (fuse pullers) protect technicians from shock and short circuits when installing or extracting cartridge fuses.
