Morning all
I had a fault last week where the earth leakage tripped intermittently, so I arrived tested the earth leakage and tripped at 16ma. This is low so before changing I continued to test and found that the customers motor had condensation on the terminals. Dried out and all ok.
I then proceeded to changed the earth leakage as I would like it to trip between 20-25ma and to my surprise any earth leakage I tried still tripped at 16ma.
Any ideas the reason for this?
