 OPERATING PRINCIPLES
 EARTH LEAKAGE TESTS
 The testers may be used to check the trip point (Test 1) of the ECLB or the trip time (Test 2). Test 1 is normally used on instantaneous ELCBs while Test 2 is normally used on inverse and fixed time-delay ELCBs.
 TEST PROCEDURE
 Test 1 - instantaneous ELCBs A ramp current, increasing at approximately 12 mA/s is introduced between L and E and the point at which the ELCB trips is recorded. To save time and reduce energy dissipation, the starting point of the ramp may be selected.
 Test 2 - inverse and fixed time delay ELCBs. Aconstant current is selected and injected between L-E and the tripping time is recorded.
