A Complete Toolkit for EVSE Professionals

In the rapidly expanding world of electric vehicles (EVs), the infrastructure supporting them is just as critical as the vehicles themselves. For electrical professionals, this means a new and complex set of challenges, particularly when it comes to the installation and maintenance of Electric Vehicle Supply Equipment (EVSE). A standard multifunction tester, while versatile, is often ill-equipped to handle the specialized requirements of these systems, which include unique RCD types and specific loop impedance characteristics. The KEW 6516BT Multi Function Tester, paired with the 8602 EVSE Adapter, represents a purpose-built solution to these challenges. This integrated kit is meticulously engineered to provide an extensive array of testing capabilities, ensuring that every EVSE installation is not only compliant with the most stringent safety standards but also operates flawlessly. It is a comprehensive tool designed to simplify complex diagnostics, consolidate multiple testing functions into a single robust unit, and empower professionals with the confidence to work safely and efficiently in this new technological frontier. The combined power of these two devices transforms the way EVSE is installed, maintained, and certified, putting a complete and powerful diagnostic suite directly into the hands of the technician.

Foundational Safety Checks for EVSE Installations

Before any power is applied to an EVSE unit, a series of critical safety checks must be performed to ensure the integrity of the cabling and the grounding system. This is what the KEW 6516BT and 8602 adapter kit excels at under dead-line conditions (CP STATE A). The kit facilitates a thorough Insulation test of the cable, ensuring that there is no leakage current between the conductors and the earth. By connecting the test leads directly to the adapter terminals, the professional can accurately measure the insulation resistance for both single-phase and three-phase EVSE cables. While this test covers the vital connection to the protective earth, it is important to note that insulation measurement between the live conductors (N, L1, L2, L3) themselves is not within its scope, which is a key detail for professionals to remember. Furthermore, the kit enables a precise Earth Continuity test at 200mA. This test is essential for verifying that there is a proper, low-resistance path between the adapter’s PE (Protective Earth) terminal and the outer metal parts of the EVSE or the earth of the main electrical circuit. A solid earth continuity is the bedrock of electrical safety, and this test provides a definitive verification of its integrity. Finally, the kit includes a comprehensive Earth test (with both 3-wire and 2-wire capabilities), allowing professionals to measure the resistance of the earth connection to which the EVSE is connected. This is a vital step in confirming the effectiveness of the grounding system, ensuring that in the event of a fault, current will be safely dissipated to the ground, preventing potential harm.

Verifying Power and RCD Performance Live

Once the foundational dead-line checks are complete, the next phase of EVSE installation involves verifying the live-line conditions. The KEW 6516BT, working in conjunction with the 8602 adapter, is fully equipped to handle this with precision under CP STATE C and D. The professional can easily measure Voltage and frequency between each terminal to confirm that the power supply is stable and within specified parameters. For three-phase installations, the Phase rotation can be measured to ensure that the phases are correctly sequenced, which is crucial for the proper operation of the EVSE and the safety of the entire system. One of the most significant and specialized capabilities of this kit lies in its RCD test functionality. EVSE units often contain a unique 6mA DC RCD designed to protect against potential direct current leakage, a common occurrence during EV charging. Standard testers are not typically designed to test this specific RCD type, but this kit provides a dedicated test for it. Professionals can verify the RCD’s operation with polarity tests (+,-), as well as x1/2, x1, and x5 tests, all of which can be performed in an auto-test mode for efficiency. The kit’s versatility extends to testing a full spectrum of other RCD types, including Type AC, A, B, and F, ensuring that the professional is prepared for any scenario, whether it’s a dedicated EVSE RCD or a general-purpose breaker. This comprehensive RCD testing suite is a key differentiator, providing the peace of mind that all protective devices are fully functional and ready to safeguard against electrical hazards.

Low Current Loop Impedance for EVSE

The measurement of loop impedance is a critical safety check, but when it comes to EVSE, it presents a unique challenge. Standard multifunction testers are typically designed to measure loop impedance at currents that will not trip a common 30mA RCD. However, the specialized 6mA DC RCDs built into EVSE units are far more sensitive and will often trip even at these low currents, frustrating professionals and making accurate testing impossible. This is where the KEW 6516BT and 8602 adapter truly stand out. The KEW 6516BT series, with firmware version 2.10 or later, introduces a dedicated “L-PE 3W EV” mode within its Loop ATT (Anti-Trip Technology) function. This innovative mode specifically reduces the measurement current to prevent the sensitive 6mA DC RCD inside the EVSE from tripping during a loop impedance test. The professional can choose between “Normal I” (6mA at 5.3Hz) and “Low I” (4mA at 5.3Hz) with a simple switch on the device, providing an unprecedented level of control and precision. This specialized, low-current measurement capability ensures that a professional can get a reliable loop impedance reading without causing an unnecessary power interruption. This dedicated functionality is a testament to the kit’s forward-thinking design, addressing a real-world problem that professionals face daily and providing a solution that is both effective and efficient. This feature alone makes the kit an indispensable tool for anyone involved in the installation or maintenance of EV charging infrastructure.

The Adapter’s Role in Comprehensive Diagnostics

While the KEW 6516BT is a powerful multifunction tester in its own right, its true potential is unlocked when used in conjunction with the 8602 EVSE adapter. The adapter itself is far more than a simple connector; it is a sophisticated simulation tool that allows the professional to manipulate and test the EVSE’s behavior. The 8602 adapter can simulate various CP (Control Pilot) states (A, B, C, D) and PP (Proximity Pilot) states (OPEN, 13A, 20A, 32A, 63A). This allows the professional to force the EVSE into different operational modes for comprehensive testing. For instance, simulating a CP STATE A allows for the dead-line testing of the cable, while simulating CP STATE C or D allows for the live-line tests of voltage, phase rotation, and RCDs. The adapter also includes terminals for E, N, L1, L2, L3, and CP, providing direct and safe access to all critical points for measurement. This combination of the 6516BT tester and the 8602 adapter effectively creates a closed-loop system for EVSE diagnostics. It enables the professional to not only measure the electrical parameters but also to test how the EVSE unit responds to different simulated conditions, ensuring that its control logic and safety features are working as intended. This level of integrated functionality is essential for a thorough and reliable certification process, giving professionals the tools they need to guarantee the safety and functionality of every EV charging point.
