6 Best Circuit Analyzers for Electricians

One of the responsibilities of an electrician is to make sure that electrical systems and equipment are well-maintained to avoid possible disasters and accidents. To do this, they would require tools such as circuit analyzers.

A circuit analyzer is a special device for testing and determining faults on a line that may lead to complications such as electric fire, electric shocks, and malfunctioning of equipment. This tool is equipped with features in order to give the electrician accurate measurements and information about any building’s electrical system.

Best Circuit Analyzers

For every electrician, they must be equipped with high-quality performance tools. Below, you will see a list of the most recommended brands of circuit analyzers.

1. Extech CT70 AC Circuit Load Tester

The Extech CT70 is both a GFCI and AC Circuit Analyzer perfect for covering tasks like outlet load handling and outlet tester function. It can measure both loaded and unloaded AC line voltage, as well as display the frequency and peak line voltage. The device can also show the percentage of the voltage drop and line impedance. It even has selectable loads of 12, 15, and 20 Amps.

The outlet tester can display the hot, neutral, and ground impedance, the GFCI trip time and trip current, neutral to ground voltage, open and reversed wiring, and Available Short Circuit Current. Apart from that, the device also features a large LCD display that shows big, readable digits, and colored alerts for a pass or fail. It is complete with an AC test cord, which is considered to be the standard North American 3-prong plug. View the product

2. SureTest Circuit Analyzer

This device is ideal for checking electrical outlets that may cause electrical fires, personal shock hazards, and other performance issues regarding equipment. It can identify dedicated circuits, false grounds, and proper wiring in 3-wire receptacles. It measures hot, neutral and ground conductor impedances as well.

This circuit analyzer is equipped with true RMS and can measure a voltage drop that is under 12, 15, and 20 amp loads. The device’s design is built for better grip and maximum comfort, all while ensuring accurate readings. It comes with a premium neon lamp and is encased in high-resistant material. The product also includes an extension cord that is up to 1 foot. View the product

3. Klein Tools RT310 AFCI

This tool has the ability to detect common faults in wiring, particularly in standard, GFCI, and AFCI electrical outlets. It is built to detect dual open wiring faults that have simultaneous open neutral and ground wires. The device is specially designed to use with North America 120V electrical outlets.

The tester of this tool is sure to give clear and accurate visual indications regarding the wiring condition of the electrical outlets. The AFC devices can be tested by stimulating the arc fault conditions; while the GFCI devices are checked by stimulating the ground fault conditions.

The product is also equipped with a low battery indicator and comes with three 1.5V AAA Alkaline batteries. It also has an electric plug of 10 inches. This flexible cord allows the device access to outlets in difficult locations and tight spaces. View the product

4. MASTECH LCD Circuit Analyzer MS5908A

The MASTECH LCD Circuit Analyzer is best described with its high performance and multiple functions. The tool guarantees easy to use operations and accurate measurements. It works best with fast fault locations and AC low-voltage distribution lines. It functions efficiently when it comes to detecting problems that root from electrical fires, electric shocks, and faulty operation of equipment. The tool is also equipped with true RMS value that can read AC voltage.

More than that, this circuit analyzer can measure several factors such as frequency, peak voltage, phase voltage, and the ground voltage. It can check the readability of the residual current device and the action time. It also tests the reliability of GFCI action and response action time.

The tool’s design is built for durability and purpose. It is made with a material that protects the tool from damage brought by collision. It has a backlight and data retention function to enhance the product’s performance. The overall package comes with the device itself, a power cable, an instruction manual, and a carrying box.

5. Camco Heavy Duty Dogbone RV Circuit Analyzer With Power Grip Handles

The main attraction of the Camco Heavy Duty Dogbone RV Circuit Analyzer is its power grip handles which ensures an easier and safer way to plug and unplug. Its main function is to give additional protection for electrical equipment against improperly wires electrical boxes.

The device is equipped with diagnostic lights in order to give visual indications on the status of source circuits and possible faults. The different lighting combinations are efficient in informing the user of issues involving the electrical wiring. If the lighting sequence shows, “correct wiring”, then it means you can connect to your RV.

More than that, this tool also has a surge protection feature that can go until 2100 joules. If a surge does happen through a power pedestal, the analyzer will surely intercept it. View the product

6. Amprobe INSP-3 Wiring Inspection Tester

Last on our list is the Amprobe INSP-3 Wiring Inspection Tester, which is a tool that can give you fast and accurate results. It is best suited for checking if the wiring in a building complies with the electric code. It can detect faults such as incorrect and undersized wiring, wrong line voltage, poor ground quality, and problematic GFCIs and AFCIs. With this tester, you can select a 10, 15, or 20 amp load.

This device is guaranteed safe, as it is built to prevent the blowing of fuses or breaking of circuits while a test is ongoing. It has an additional feature of a large display that can show the test data regarding possible issues with connections, conductor quality, and splices. All of this valuable information can be viewed without the need for switching screens or scrolling. If a flashing screen is seen, that means there is a failure detected in the wiring.

The box includes the product itself, 9V alkaline batteries that are already installed, a power cord, a user’s manual, and a carrying case. View the product
