How to test Earth Continuity and Insulation resistance on a hard wired appliance.
NAC-Trainer May 21, 2020
This lesson will show you how to test the earth continuity and insulation resistance on a hard-wired appliance. It is important to note that we carry out these tests before and after every repair. Firstly to highlight any potential electrical faults with the appliance and to give you a baseline reading to compare your final set of results to. The tests performed after the repair are to prove you are leaving the appliance in a safe working condition for the customer.
A hard-wired appliance is any appliance that does not have a connection or plug that can be disconnected by the user and is instead connected to a fixed point.
