MODULE 2: CORE ELECTRICAL HAND TOOLS
[COMPREHENSIVE EXAM AND PRACTICAL STUDY GUIDE]
======================================================================
MODULE INTRODUCTION & TECHNICAL REQUIREMENT
----------------------------------------------------------------------
* Using the correct tool for a specific electrical job saves labor
time, prevents damage to sensitive components, and protects the
operator from fatal injuries.
* Hand tools used by electricians must have proper insulation sleeves
rated and certified up to 1000V AC safety standards.
DETAILED DISSERTATION ON COMBINATION PLIERS
----------------------------------------------------------------------
* Technical Definition: A multi-purpose, heavy-duty hand tool engineered
with diverse gripping and cutting sections on a single head.
* Primary Functions:
- Flat Gripping: The serrated nose holds flat plates and sheet metals.
- Pipe Gripping: The curved, serrated jaw holds round pipes and rods.
- Wire Twisting: Makes robust mechanical joints by twisting conductors.
- Side Cutting: Side blades shear through small copper and aluminum wires.
* Specification Standards: Electricians generally use the 150mm and 200mm
sizes based on total length from head to handle base.
* Maintenance Protocols:
- Never use combination pliers as a hammer; it cracks the forged steel.
- Do not attempt to cut hardened steel wires or high-tensile hot lines.
- Apply clean lubricating machine oil to the pivot joint regularly.
SPECIALIZED ELECTRICAL PLIERS AND THEIR APPLICATIONS
----------------------------------------------------------------------
* Flat Nose Pliers:
- Features: Possesses long, flat, rectangular jaws with smooth interiors.
- Applications: Making sharp, precise bends in narrow metallic sheets.
* Round Nose Pliers:
- Features: Jaws are tapered into perfect conical shapes.
- Applications: Forming uniform loops, rings, and eyelet shapes with wire ends.
* Side Cutting Pliers (Diagonal Pliers):
- Features: Engineered exclusively with flush cutting edges.
- Applications: Cutting wire conductors inside crowded junction boxes.
* Long Nose Pliers (Nose Pliers):
- Features: Long, elongated jaws with tapering tips.
- Applications: Retrieving fallen screws or holding tiny washers inside
deep electronic enclosures where fingers cannot reach.
