Electrical tools and materials are essential for electricians and homeowners alike. Electrical tools are devices that use electrical energy to perform tasks, generate, distribute, or control electrical power. They include tools such as hammers, screwdrivers, wire cutters, and voltage testers, which are used for repairs, installations, and maintenance. On the other hand, electronic tools operate using electronic circuits and are used for processing or transmitting information, such as computers and smartphones. Understanding the differences between these tools is crucial for technology and engineering professionals. This knowledge ensures that the right tools are used for specific tasks, improving outcomes and safety, especially in electrical work.

What You'll Learn
Safety equipment
Personal Protective Equipment (PPE):
- Insulated Gloves: Made of rubber or insulating materials, these gloves protect against electric shock when working on live circuits.
- Safety Glasses: Safety glasses with side shields or goggles protect the eyes from flying debris, sparks, and other hazards.
- Face Shields: Face shields provide additional protection to the face and eyes against larger hazards, such as arc flashes or chemical splashes.
- Earplugs: Foam or other materials earplugs protect the ears from excessive noise levels when operating loud electrical equipment.
- Hard Hats: Hard hats with electrical insulation properties safeguard against falling objects, electrical shock, and impact hazards.
- Safety Footwear: Non-slip, electrically insulated shoes with protective toe caps prevent injuries from dropped objects and misdirected electricity.
- Flame-Resistant Clothing: Arc flash suits and flame-resistant clothing help resist ignition and reduce the severity of burns in case of arc flash incidents.
Insulated Tools:
Insulated tools provide an extra layer of protection by preventing the flow of electricity from a live source to the user. They are designed with insulating materials, typically rubber or plastic, applied to conductive surfaces. Insulated tools should always be used alongside other safety practices and PPE.
Other Safety Measures:
- Clear Signage and Labeling: Visual aids and proper labeling of electrical hazards are essential to raise awareness and caution among employees.
- Training and Drills: Regular safety training and drills inform employees about electrical hazards and the correct use of safety equipment.
- Safe Tool Practices: Always use the right tool for the job, inspect and maintain tools, and ensure all connections are suitable for the working conditions.
- Grounding and GFCIs: Ground tools and machinery as required by OSHA, and use ground-fault circuit interrupters (GFCIs) to reduce the risk of electric shock.
- Specialized Flooring: Use switchboard matting or insulating mats to prevent electrical shock and provide a safe working area.
- Protective Covers: Use protective covers to keep electrical equipment safe and ready for use.

Screwdrivers
The handle, made of rubber, plastic, or wood, is where the user grips the screwdriver while driving in a screw. The shaft is the long metal part of the screwdriver, made of tough steel to resist bending. The tip, located at the top of the shaft, is the part inserted into a screw. Screwdriver tips come in various shapes, including the flat-wedge shape of a slotted screwdriver, the cross-shape of a Phillips screwdriver, the six-sided hexagon, and the square-shaped Robertson. The triangular screwdriver head is less common but is beneficial as its design makes it more secure and tamper-proof. Screwdrivers with magnetic tips can attract screws by magnetic force, making them useful for working with small screws that can be easily dropped.
Electric screwdrivers can be cordless and are generally compact power tools good for various tasks. Impact drivers are a heavy-duty type of electric screwdriver, intended for tightening or loosening fasteners using sudden force to drive into or remove from harder, denser materials. Precision screwdrivers are used for small screws in devices such as watches, phones, computers, and monitors. Electricians may carry ergonomic ratchet screwdrivers with interchangeable bits, so they always have the proper tool.

Voltage testers
When working with electrical wiring, it is important to have the correct tools to ensure safety. Voltage testers are a simple yet effective way to do this. They are a basic tool that can help prevent electrical shocks and accidents.
In addition to voltage testers, other specialty electrical tools include wire strippers, linesman pliers, and fish tape. These tools are used for specific electrical tasks and are designed to make electrical work safer and more efficient.

Wire strippers
There are various types of wire strippers, including automatic wire strippers, which adjust to the correct cable size, saving time and effort. Self-adjusting wire strippers are ideal when working with cables of different cross-sections. These wire strippers are designed to strip the cable to a set length, with the desired length being regulated by a length stop.
Some wire strippers are combination tools, which can crimp wires and strip the vinyl jacket off non-metallic sheathed cable. This is a useful function, as crimping tools are essential when installing connectors on cables.

Pliers
Lineman's Pliers
Lineman's pliers, also known as linesman pliers or combination pliers, are used mainly by electricians to bend, grip, twist, and cut wires and cables. They are made of hardened steel with insulated handles, and have rounded jaws for bending wire and a cutting edge for snipping it. Their squared-off, serrated nose provides a secure grip. They are used mostly in electrical work, like installing and repairing wiring systems, and in telecommunications and network engineering.
Needle-nose Pliers
Needle-nose pliers, also known as long-nose pliers, are used for precise tasks that require attention to detail, such as bending, re-positioning, and snipping wires. They have long jaws with a serrated surface to help grip small or smooth objects, and cutters at the back of the jaws for cutting through plastic clips, staples, or wiring. They are not designed for heavy-duty projects, so the tip may bend or break if not treated with care.
Bent-nose Pliers
Bent-nose pliers are similar to needle-nose pliers, but instead of straight jaws, they have hooked jaws. This allows them to access hard-to-reach locations while keeping your hands and the bulk of the tool out of the way. They are used for gripping, cutting, and bending wires, but are not ideal for tightening or loosening fasteners.
Cutting Pliers
Cutting pliers, also known as diagonal pliers or wire cutters, are used for cutting wire, nails, and other materials. They have a sharp edge and a pivot near the cutting edge, providing leverage for cutting through tough materials. They are typically made of high-quality steel and have insulated handles for safety.
Other Types of Pliers
There are many other types of pliers, including fencing pliers, oil filter pliers, snap ring pliers, locking pliers, and grip pliers. Each type has a specific function and is designed for different tasks. For example, fencing pliers are used for installing, repairing, and maintaining fencing, while oil filter pliers are used for removing oil filter housings from vehicles.
