    Insulation testers test the insulation resistance of the material that is being used to insulate cabling this is usually done at double the level of resistance for the material in many countries standards and safety agencies have specified this is a universal test and all products must be tested this test is often done after every maintenance procedure or repair. Insulation needs to be tested to check that it can cope with power surges and prevent fires.

    What are RCDs and Why do they need to be tested?

    RCDs are usually built in devices that measure residual current, they are designed to trip if the residual current becomes too high, they are designed to protect you from electric fires or from electrocution this is done to be in accordance with BS7671
