Although the necessary basic tools vary by job, most toolmakers contributing information for this report said many electricians have a basic set of tools that includes pliers of various types, wire cutters and strippers, crimpers, multibit screw and nut drivers, a utility knife, a tape measure, a level and hex keys. Without question, most basic hand tools on the market today are better than similar products sold a decade ago.
In addition to expanding functionality so one tool can serve more purposes, toolmakers have created new specialty tools that fill distinct niche uses based on observed behavior. Whether new construction?or repair and maintenance work, integrated systems contractors sometimes require temporary, portable power sources.
Electric motor failure can cause numerous problems, ranging from inefficient power use, equipment damage and costly downtime. Keeping track of tools—whether just a few or hundreds—is a challenge that computers have made much easier. The list of hand tools that are essential to electricians has mostly remained unchanged over the years.
Sometimes, electricians and electrical contractors must work in areas where no electrical service is available.

Electrical tools are essential to perform electrical installation works safely, efficiently and correctly.
Electricity deals with high voltages and currents , so the work involved in the energized circuits can’t be done without use of proper tools.
The list of basic electrical tools and equipments is a bit longer; however the list can be shorter depending on the type of electrical work being undertaken. When working on industrial installations, additional tools are required to handle complicated task. A Lineman’s pliers with cutter is used for twisting of wires together for a tight connection and also for cutting, gripping and bending the wires.
Screwdriver is must for an electrician or any person working with an electrical circuit or equipment. The Robertson tip or recessed square shank type screwdriver is used Robertson or square head screws.
By touching the metal part of one end (top of the tester where neon bulb is placed) and making contact of metallic rod with the circuit to be tested, the neon bulb lights up indicating that hot wire and if it doesn’t indicate, it is a dead circuit. Two-wire neon tester is another type of electrical voltage tester which determines if any component of wire is powered-up or not. Multipurpose digital line testers are the non contact testers which detects the voltage without having contact with live wire. Ground fault testers are used to check the operation of a ground fault protected wall receptacle. It is used for horizontal and vertical leveling while installing electrical cabinets and EMT conduits.
Fish tapes provide less surface contact and rigidity for long distances when pushing through crowded conduits.
Every electrician must carry electrical tapes for quick identifying of electrical wires, circuits, conduit systems and containers. It is needed to cut or remove the insulation of wires, stripping of PVC jacket from Romex wiring, and to do many other jobs. Most commonly these are used as voltmeters to measure the voltage across the equipment or load. These are used to measure the speed of the moving objects, especially for measuring the speed of the motors and machines.
You’ve probably been wondering when we were going to finally switch it up a little, get away from that nasty steam and HVAC stuff.
I discovered this electrical fundamentals book that lays out the basics first and then eventually gets into circuits, motors, and controls and more. Before we get into the first section of defining an electrical charge, let’s remember back to one of our first engineering fundamentals posts where we talked about matter, molecules, and atoms.
We all have heard about atoms; they have a nucleus made up of protons and neutrons and then skirting around the outside in an orbit (like the solar system sort of,) are electrons.

A material that either attracts or repels another charged material has an electrical charge. The atoms of different elements have different numbers of protons, neutrons, and electrons from one another. Electrons have a negative electrical charge and are also much lighter in mass than protons. Not every material likes helping out the flow of electrons, some things don’t make good conductors.
If we were to hold the resistance in a circuit constant, we can alter the current by changing the voltage. Increase in voltage equals increase in current. Once again, we are starting with the building blocks of everything and talked about the components of an atom – the protons, neutrons, and electrons. If the material is not all keen on helping out the movement, it is not a good conductor and would probably make a better insulator. Reading Electrical Schematics Learning how to read electical schematics will help you understand your home’s electrical wiring and systems. When you look at the wiring diagram that your architect created as part of your house plans, it might seem to you as if he was providing some sort of ancient hieroglyphics to you.
Essentially, the wiring diagram of your home is a copy of the floor plan, with symbols showing the locations of all your electrical switches, lights and outlets.
Related ArticlesInstalling Electrical Switches: Installing electric light switches is part of the finish electrical. Hand tool product manager Fee said the tradeoff with cordless tools has always been finding enough power with enough run-time that did not require a 50-pound backpack full of batteries. Basic tools extend the physical responses of the human body which makes the job much easier and faster. Here, we have listed some of the basic portable tools popularly used while dealing with electrical installation and troubleshooting. If the installation work is to be carried at new houses or rewiring old houses, the number of electrical wiring tools required is not a big number. These are specially designed such that the cutting edge goes down to the tip of the pliers. These are designed with different sized cutting teeth in order to cut the different sized wires. Holes provided on this tool helps to make loops of the wire for the termination on switches. These are used to loose or tight the screws that are placed in various electrical devices like switches, breakers and equipments. So the proper screwdriver has to be selected that best fits the need.A Phillips screwdriver consists of four blades such that it tight or loose the Phillips-head screws. Depends on the screw size, the corresponding tip or blade size of the screwdriver is selected. The right tip of the screwdriver for a particular screw is selected with the symbol on the domed end or with color coded handle. It can be anything like they simply light up or indicates in some other way that differentiate between the choices of dead circuit or live circuit. However, these testers give inconsistent readings if the wires are covered by metal conduits. These testers will give indication of ground fault with red and yellow lights when these are inserted into the ground fault receptacle. These are stick to anything so that proper leveling can be obtained for the object being placed. These are used for linear measurement markings in electrical installation works while placing light fixtures, distribution boards, etc. These are also used as primary insulation for splices (joints that are made while connecting two circuits). Depending on the requirement of the drill, drill bits have to be selected from variety of sizes.
Some of the advanced type meters also allows to measure frequency, capacitance, temperature an duty cycle. We’ll get back to it soon enough as those are both huge parts of building engineering.
Two materials with positive charges will repel each other, as will two objects or materials both with negative charges.

The good ones we use as conductors, the bad ones are called insulators – rubber, wood.
If we have this massive amount of voltage trying to create this electrical pressure but we have a poor conductor, more like an insulator, we won’t have a flow of electrons so no current. Electrons always flow from negative to positive, kind of like how heat is transferred from warmer to cooler.
Fear not, this isn’t an ancient language; it’s just a symbolic representation of your home’s electrical wiring and systems. The curved lines are the wiring running from switches to the lights and ceiling fans; showing which switches should control which lights. These are made with metals and consist of insulators in handle, in order to avoid shock while performing the job.
It can also be used for multiple tasks such as holding screws for drilling and reaching dropped screws.
So the neon bulb will give a light when the two probes are connected to respective line and neutral terminals provided the power is present on the wires. These are essential for leveling cover plates, outlet boxes, wall fixtures, light fixtures, etc.
Low voltage cordless drills (which incorporate rechargeable batteries) are used for fastening work and generally used where electric supply is not available.
The magnet on the clamp meter measures the magnetic fields and converts it into appropriate current value.
One must wear the gloves while working with high voltages in order to avoid short circuit faults and to reduce the danger to the personnel. When we have two materials with opposite charges, one negative and one positive, they attract. You’ve probably noticed when replaces the batteries in a device the plus and minus symbol.
The electrons are getting the same electrical pressure force behind them but having to work less to move in a good conductor. Using an electrical pressure, voltage, we can knock the electrons out of their normal orbit paths into the next one. They are curved, because the exact location and routing of those wires is left up to the electrician making the installation. But, if you want to be efficient, fast and cost effective in the long run, having the essential woodworking power tools in your arsenal is a must.There are a number of power tools out there in the market. By looking at the periodic table of elements you can tell how many of each make up an atom of that element. It can carry out a number of tasks with precision, right from cutting a wood stock straight or at an angle. Whether you have to mill a stock for joinery work or just basic smoothing, it can do it all with ease. Whenever you decide to buy a tablesaw, make sure that you buy a good quality and sturdy one.
This is going to be the most used equipment in your workshop, so buying a cheap one compromising the quality is not a sound decision. It is capable of doing a number of woodworking tasks like making patterns, joints like, rabbets, mortises, etc.
But, if you are well versed with the use of a router and want the advanced one, go for a plunge router. In matter of minutes, you can get the desired smoothness and thickness of stock.There is no doubt about the fact that these essential woodworking power tools will make executing wood projects easier.
But, one thing you have to keep in mind is that you have to be extra cautious about the safety precautions.
Of course, as you move forward in your woodworking career you can add new power tools in your workshop as per the need of your wood projects.
