Amprobe TL-8000-25M | 25 Meter Test Lead
Amprobe TL-8000-25M | 25 Meter Test Lead for easy earth bond continuity verification and R2 measurements.
This is an essential electricians accessory ideal for ceiling roses, light fittings and circuits far away. It is the only way to test for earth bond continuity as well as for R2 measurements.
First, measure the resistance of the test lead itself and record, or if using auto-null facility on your continuity tester, zero out this resistance. Unwind the appropriate length of test lead cable, then connect your tester to the extension reel’s central 4mm connector and to the point to be tested.
Please note: One end of the earth bonding should be disconnected to avoid parallel earth paths.
