Why Does Your Business Need Regular Leakage Current Testing?

Posted: July 03, 2024

When it comes to electrical safety, there are some common parameters we all take care of. Like, we keep checking the quality of cables, whether electrical equipment is properly working or not, and so on, however, one thing we often miss is leakage current testing. 

Let’s understand the significance of RCD Test Tags or leakage current testing for both high-voltage and low-voltage circuits, detailing regulatory requirements and practical benefits for your commercial settings. 

About Leakage Current Testing 

Leakage current testing is a procedure operated to evaluate the unintended current that escapes from an electrical circuit to the ground or surrounding conductive materials. This is vital in pinpointing potential electrical faults that could lead to safety hazards, equipment failure, or even fire incidents. 

Leakage Current Testing for High-Voltage Circuits 

For high-voltage circuits, regulation 5.24(2) mandates that the earth leakage protection device must operate at a maximum allowable earth leakage current not exceeding 2 A. This regulation ensures that any leakage does not exceed safety limits, thereby minimising risks associated with high-voltage operations. Maintaining these limits is crucial in preventing unsafe steps and touch voltages, which could be hazardous to personnel and equipment. 

Leakage Current Testing for Low-Voltage Circuits 

Similarly, for low-voltage circuits, regulation 5.24(2) requires the earth leakage protection device to operate at a maximum allowable earth leakage current not exceeding 1 A. This regulation focuses on maintaining safe touch voltage limits, protecting users from electric shocks, and ensuring the reliable operation of low-voltage equipment commonly used in commercial settings. 

Why Regular Leakage Current Testing is Essential? 

1. Safety Assurance: Regular Electrical RCD Testing assures that all safety mechanisms are operating well, decreasing the risk of electric shocks and fires. 

2. Compliance with Regulations: Sticking to regulatory standards enables avoiding legal penalties and assures a safe working environment. 

3. Preventive Maintenance: Recognizing and managing potential issues before can prevent costly equipment failures and downtime. 

4. Insurance and Liability: Many insurance policies need compliance with safety standards, including regular current leakage testing, to maintain coverage. 

5. Operational Efficiency: Well-maintained electrical systems function more efficiently, reducing energy costs and improving overall productivity. 

Implementing a Regular Testing Schedule 

To effectively implement leakage current testing, businesses should establish a routine schedule. Ensure that all testing is conducted by qualified Industrial Electrical Contractors who are familiar with the specific requirements for high and low-voltage circuits. 


In all, investing in regular leakage current testing is a commitment to safety and operational excellence.
