What was the answer for the legal status? I put duty holder for both !!
Does anyone know if you can even use an RCD on an IT system?
I found a copy of the paper on the bus going home last night. Weird!
Question 16 referred to an IT system:
"State the test instrument used to measure the earth electrode resistance fo an installation protected by an RCD and forming part of a [sic] IT system"
Does anyone know if you can even use an RCD on an IT system? Did they mean "a TT" rather than "a IT" system?
I waffled on about using an insulation resistance tester to measure the high impedance path to earth.
