4.4.4 EL Test Connections (Terminals 4 & 5)
The Earth Leakage Test works by closing an internal normally open contact for the duration of the test.
This contact is intended to be wired in parallel to an existing earth leakage test circuit that passes an
AC current through the outlet’s earth leakage toroid.
NOTE
The installer is responsible for ensuring that the test resistance is of a
suitable magnitude to provide a meaningful test.
It is recommended that the resistance value is chosen such that the test
current is between 110% and 120% of the trip level of the earth leakage
protection relay (AS/NZS 2081 Appendix E4, AS/NZS 4871.1:2012
Clause 2.6.2.4).
