When were RCD's Tested at 2x?

eveares · 19 Nov 2016

I have a old Seaward RCD tester that tests the tripping time at 1x, 2x, and 5x of the RCD's rated tripping current.

It tests 10mA, 30mA, 100mA, 300mA and 500mA rated RCD's, both at 0° and 180°.

When was this type of RCD tester in mainstream use, as I have not heard of modern RCD testers being capable of carrying out a 2x test.

Regards: Elliott.

If I recall it is a test designed for DC currents

The Metrel equipment I have used have all had a 2x test built-in, even the so-called "17th Ed. testers"

I have this from the IET forum:
