Basic Electrical Repairs – Tools and Techniques

If you are a DIY homeowner, you probably know that basic tools and techniques are an essential part of any home electrical repair or upgrade project. The good news is that many of the tools you need for your next electrical fix are fairly simple to acquire.

One of the most important tools you need to have for basic electrical repairs is a wire stripper/cutter. This tool removes the outer covering of a copper wire before you make a connection.


Wire Stripping Tool

The Wire Stripping Tool is an essential piece of equipment for anyone involved in electrical repair. It can be used for stripping wires that are needed to make connections at receptacles, switches, lights or junction boxes.

A wire stripper is a hand-held tool that has labeled holes that match wire gauges from 10-gauge to 20-gauge, and it severs insulation without nicking the copper wire. It also has a cutting blade that can be used to separate segments of insulation from the wire.

To use a wire stripper, insert the end of the wire into the labelled hole, and squeeze the handles. The blades in the tool are designed to cut through the plastic insulation layer of the wire, allowing the copper wire to come free.

Once the stripper has cut through the insulation, you can begin to pull the stripper away from the wire and remove it from the sheathing. This process can be done quickly and efficiently with the right tools, but it is important to remember to take the proper safety precautions.

Before attempting to strip any wire, be sure that it does not carry electricity. You can test this by hooking up a multimeter to the wire and turning it to the voltage setting. If it stays at zero volts, the wire is not carrying electricity and you should shut off the power supply before trying to strip it.

If you are working with solid core wire, be extra careful with your choice of a notch on the tool. The notch should be a perfect fit for the gauge of the wire, and it should not be too small or too large. A nick in the wire will severely compromise its strength and flexibility, which can lead to broken or twisted wires.

The best wire strippers are self-adjusting, which means they automatically adjust their cutting diameter to the cable’s cross-sectional shape. This can save you time and effort when dealing with wires that have different gauges.

There are many different types of wire strippers, and they all have unique features that make them better for certain applications. Some are abrasive wheels, which abrade the wire insulation and allow the wire to come loose; others feature a rotary blade that cuts the ends of the wire. Most have a tensioning knob that allows you to control the pressure in the jaws, which is important for stripping the insulation without causing damage to the wire.

Fish Tape

If you are in the market for a new tool that will help with basic electrical repairs, consider grabbing a Fish Tape. It is a very useful tool that is often used by electricians to pull wire through walls and conduit.

Despite its name, it has nothing to do with fish at all, and is actually made of steel or fiberglass. It is a very versatile tool that can be used in a variety of ways, from pulling wire through walls to connecting it to a battery and bell.

To use fish tape, simply insert the hook into a hole in a wall or conduit and then start pulling from the other end. This method is great for pulling wires through tight spaces, such as around corners and in narrow areas where people cannot reach.

You may also need a few fish tapes to complete a job, especially if you are planning to run wire through many different areas of a home or business. For example, you might need a fish tape that is three feet long to move a wire three feet through a wall.

Professionals usually have a few different lengths of fish tape on hand at all times for different tasks, so make sure you have a few extras on hand if you are going to be doing a lot of work. For instance, if you are working on a project that will take a few days, it is probably best to have a 100 foot roll on hand for large jobs, but a 50 foot tape might be more suitable for smaller projects.

A good fish tape should have a self-tensioning case for easy winding and rewinding. Some of these cases have viewports to allow you to see the length of the tape you are winding.

Another important factor is the material of the tape itself. Some fish tapes are made of stainless steel, which is ideal for basic work, while others are made from fiberglass, which can be a better choice when working near live circuits or in wet conditions.

Electrical Tape Measure

One of the most basic tools for basic electrical repairs is the electrical tape measure. It is a tool that many advanced DIYers and professional electricians use on a regular basis to help them with their electrical work.

A good electrical tape measure can be used for a variety of tasks and is especially useful for covering wires and making connections. In addition, it can be used to bundle wires together. This helps to make sure that the connection is secure and prevents shorts.

It is important to find a high-quality electrical tape that has excellent stretch and adhesive strength. This will allow the tape to remain in place and protect it from moisture, dirt, water, and other environmental hazards.

You will also want to make sure that the electrical tape you choose has a rating of at least 600V. This will ensure that it is able to handle any kind of voltage that may be present in your project.

The best electric tape measures are made from high-quality materials that are designed to withstand the harshest conditions and provide long-term durability. They are also designed to resist abrasion, heat, and sunlight.

Another important feature of a good electrical tape measure is that it is resistant to extreme temperature changes. This can be an important consideration if you plan to use the tape for insulation, wiring, and other projects that require heat and/or humidity.

Most modern measuring tapes have markings every 12 inches or foot, with large numbers and small divisions that represent fractions of an inch. Some have additional markings that indicate how many joists or trusses are spaced apart, and others have a special marking every 16 inches that is a US standard interval for studs.

These marks are a good way to help you determine what you are measuring and will also give you a better idea of how long it will take for the tape to reach the other end of the object. This will help you avoid overextending the measurement and wasting time or money.

If you’re in need of a quality electrical tape measure, check out the options available at your local home improvement store. These tools can be helpful in completing all of your electrical repairs.


Voltmeters are a useful tool for basic electrical repairs. They can be used to test capacitors, resistors, and other elements in an electrical circuit. They are also useful for checking cables and wires.

To use a voltmeter, you first need to know how it works. It has a high internal resistance that limits the current flow through it, so it can measure voltages correctly. This is important because it allows you to get accurate readings on your meter.

There are a variety of different types of voltmeters, including analog and digital meters. Analog voltmeters have a mechanical pointer that moves in an arc depending on the amount of voltage present.

A digital voltmeter is a more advanced instrument that measures both AC and DC voltages. They also display the meter readings on a seven-segment display screen.

The best voltmeters have a high internal resistance, which means they can handle low current and won’t fry when you plug them into a power source. This is especially important if you are testing many different circuits in a short period of time.

When you are using a voltmeter, it’s important to remember that it should always be connected to the positive and negative input terminals of the circuit. This will allow the voltmeter to automatically turn itself on and do the measurement for you.

In addition, you should always be careful when measuring current. Too much current can fry your meter and blow its internal fuse, so it’s important to connect it to the proper port on the power supply.

You can also use a voltmeter to check the condition of a diode. This can help you determine whether or not the diode needs to be replaced. You can do this by connecting the multimeter to the diode, setting it to ‘diode test’ and testing each of the diode leads with the meter probes.

Once you have a good idea of the condition of your diode, you can determine the size and type of replacement that is right for your circuit. If you don’t know what you are doing, it can be helpful to consult a knowledgeable electrician in Columbus Ohio.
