WebThe 1660 Series installation testers also perform a pre-test to determine if the actual test will cause a fault voltage exceeding a 50 V or 25 V safety limit. To manually measure the tripping time, the RCD’s tripping current rating, a test current multiplier, the RCD type and the test current phase setting are selected using the menu buttons.
