Maintaining your systems and circuitry is essential for the durability and functionality of your business. Given the severity of electrical faults, it is crucial to test your electrical installations and power points for earth fault loop impedance. Each circuit must be tested to ensure the actual loop impedance does not exceed the specified limit for the protective device.

In most homes, basic shock protection is achieved by organising an earthing circuit with automatic switches in indoor wiring circuits. These switches automatically cut off the supply to an earthing circuit when a fault occurs, and touch voltage exceeds an acceptable limit. To comply with current national safety standards and ensure the safety of all guests and employees, it is necessary to conduct a loop impedance test at your premises.
