Testing of residual current devices (RCCBs)

• Measurement of touch voltage without tripping the RCCB. Touch voltage is measured with reference to nominal residual current using ⅓ of the nominal residual current value.
• Tripping test with nominal residual current, measurement of time to trip

Special tests for systems and RCDs

• Testing of systems and RCDs with rising residual current including an indication of tripping current
• Testing of RCDs, I?N = 10, 30, 100, 300 and 500 mA
• Testing of RCDs with half-waves (pulsating direct current) for determining the time to trip and tripping current

Testing of special RCDs

• Selective, type AC, type A
