Global IR testing on RCBO populated CU

[Midwest]

I shall be replacing my dual RCD CU, for a all RCBO populated CU. A question or two about technique for IR testing.

For the IR test, I've read here before that a global IR test is preferable. With older types of RCBO's that wasn't possible, without disconnecting cables, which ended up with the testing of each individual circuit.

I'm installing a Hager CU, with their miniature ADA RCBO. The MI state an IR test can be carried out on the RCBO terminals, circuit connected with the RCBO turned off. As I've a few different sorts of luminaire connected, I will be doing live/neutral to to earth.

How do you carry out such a test? I've seen some stackable MFT leads, so you can combine live & neutral together?

UK plug inflicts more pain to feet than any other, ergo it is best.

Joking aside, I find the heft of BS1363 plugs quite reassuring. The next best in terms of robustness (that I've encountered) would probably be Schuko, but no domestic plug mates as solidly with a socket as our 3 pin beast.

Amen to that. That's why I describe the europlugs as "flimsy". Whereas the traditional 13amp 3 pin has very much a feel of "I won't let you down" about it.

When you stand on one it won't let you down to the floor, that is for sure!

I never seemed to suffer that, but as a child my sister had an uncanny knack of finding each and every plug that was ever left prongs-up. Perhaps she save me by her self-sacrifice!
