Tester:-

Electricians use these electrical testers every day to see if a circuit or device is energized. They are crucial safety tools that keep electricians out of harm's way and tell them if there is trouble on a circuit or device. There are several different types of ​testers on the market, some with specific purposes only and some with multiple testing features. Here are the top 6 electrical testers used by professional electricians.

Drill machine:-

We use drill machine to making hole in wall and those palace their required a drill. especially we use drill machine to fix a board and casing and capping fittings.

Screw driver:-

Screwdriver, tool, usually hand-operated, for turning screws with slotted heads. For screws with one straight diametral slot cut across the head, standard screwdrivers with flat blade tips and in a variety of sizes are used.


Hammer:- 
A hammer is a tool or device that delivers a blow  to an object. Most hammers are hand tools used to drive nails, fit parts, forge metal, and break apart objects. Hammers vary in shape, size, and structure, depending on their purposes.

Wire stripper:-

A wire stripper is a portable handheld tool used by workers, especially electricians, for removing the protective coating of an electric wire in order to replace or repair the wire.

 electrician Plier:-

Doing electrical work for a profession, home maintenance, or even as a hobby requires that you have a few specific tools on hand. Among them are pliers and wire strippers. These simple hand tools may not look like much at first glance, but the benefits of having them as part of your toolbox are many. To begin with, both pliers and strippers come with wire cutters and possibly even crimpers, which can make any electrical job much easier and neater to perform.

                                 Wire type and joint

• Type of wire :- mainly two type used in electrical wiring.                                                      1. copper wire   2. aluminium wire                                               1. single strand    2. multi strand                                                  
• Single core :-A wire is a single, usually cylindrical, flexible strand or rod of metal. ... The term wire is also used more loosely to refer to a bundle of such strands, as in "multi stranded wire", which is more correctly termed a wire rope in mechanics, or a cable in electricity.  
•                       
• Two core wire :- Its wire we use any where there we connect the connection  the line and neutral.   
•                                                   
  
• Three core wire :-This wire we used where we connect the line neutral and earthing.                                                                                         
  
   
• Four core wire\ five core:-  this wire used mainly three phase supply.                                                                                                                                                                                                                Wire joint  
•   Union joint :- both side of wire  crossing each other and joint two side is called union joint.
