Useful measurements with computer
Very often in electrical engineering they used different computer programs. They are used not only for the design of electrical networks in even the smallest details, but also makes using them you can monitor the status of installations already in operation. Thanks to computer programs monitor the status of the electrical system has become almost a snap. Hold install the software with specific functions allows, for example, to measure the resistance of the electrical installations and other properties and measured in a direct way would have to be carried out in a more complicated formula.
Wikipedia - electricians and their associations
Some electricians are union members and work under their union's policies.
Electricians can choose to be represented by the Electrical Trade Union (ETU). Electrical Contractors can be represented by the National Electrical & Communications Association or Master Electricians Australia.
Some electricians are union members. Some examples of electricians' unions are: International Brotherhood of Electrical Workers; Canadian Union of Public Employees, International Union of Electronic, Electrical, Salaried, Machine, and Furniture Workers ; and the International Association of Machinists and Aerospace Workers.
The International Brotherhood of Electrical Workers provides its own apprenticeships through its National Joint Apprenticeship and Training Committee and the National Electrical Contractors Association. Many merit shop training and apprenticeship programs also exist, including those offered by such as trade associations as Associated Builders and Contractors and Independent Electrical Contractors. These organizations provide comprehensive training, in accordance with U.S. Department of Labor regulations.
In England, electricians are represented by several unions including Unite the Union
In the Republic of Ireland there are two self-regulation/self certification bodies RECI Register of Electrical Contractors of Ireland and ECSSA.
List of tools used in electric business
Electricians use a range of hand and power tools and instruments.
Some of the more common tools are:
Conduit Bender: Bender used to bend various types of Electrical Conduit. These come in many variations including hand, electrical, and hydraulic powered.
Non-Contact Voltage Testers
Lineman's Pliers: Heavy-duty pliers for general use in cutting, bending, crimping and pulling wire.
Diagonal Pliers (also known as side cutters or Dikes): Pliers consisting of cutting blades for use on smaller gauge wires, but sometimes also used as a gripping tool for removal of nails and staples.
Needle-Nose Pliers: Pliers with a long, tapered gripping nose of various size, with or without cutters, generally smaller and for finer work (including very small tools used in electronics wiring).
Wire Strippers: Plier-like tool available in many sizes and designs featuring special blades to cut and strip wire insulation while leaving the conductor wire intact and without nicks. Some wire strippers include cable strippers among their multiple functions, for removing the outer cable jacket.
Cable Cutters: Highly leveraged pliers for cutting larger cable.
Armored Cable Cutters: Commonly referred to by the trademark 'Roto-Split?' , is a tool used to cut the metal sleeve on MC (Metal Clad) cable.
Multimeter: An instrument for electrical measurement with multiple functions. It is available as analog or digital display. Common features include: voltage, resistance, and current. Some models offer additional functions.
Unibit or Step-Bit: A metal-cutting drill bit with stepped-diameter cutting edges to enable convenient drilling holes in preset increments in stamped/rolled metal up to about 1.6mm (1/16 inch) thick. Commonly used to create custom knock-outs in a breaker panel or junction box.
Cord, Rope or Fish Tape. Used to manipulate cables and wires through cavities. The fishing tool is pushed, dropped, or shot into the installed raceway, stud-bay or joist-bay of a finished wall or in a floor or ceiling. Then the wire or cable is attached and pulled back.
Crimping Tools: Used to apply terminals or splices. These may be hand or hydraulic powered. Some hand tools have ratchets to insure proper pressure. Hydraulic units achieve cold welding, even for aluminum cable.
Insulation Resistance Tester: Commonly referred to as a Megger, these testers apply several hundred to several thousand volts to cables and equipment to determine the insulation resistance value.
Knockout Punch: For punching holes into boxes, panels, switchgear, etc. for inserting cable & pipe connectors.
GFI/GFCI Testers: Used to test the functionality of Ground-Fault Interrupting receptacles.
Voltmeter: An electrician's tool used to measure electrical potential difference between two points in an electric circuit.
Other general-use tools include screwdrivers, hammers, reciprocating saws, drywall saws, flashlights, chisels, tongue and groove pliers (Commonly referred to as 'Channellock?' pliers, a famous manufacturer of this tool) and drills.
