Do you Know Which Conductors Need to be Connected During the Insulation Resistance Test?

In this video we look at the conductors that must be in place and connected before you can correctly carryout the third dead test insulation resistance. I use both a test rig and BS 7671 On-Site Guide to demonstrate how this dead test needs to be carried out to conform with the Wiring Regulations.

Do you link live conductors (line and neutral) together and test them to the protective conductor? The 2 videos links below show you 2 different techniques for linking live conductors together during the insulation resistant test.
