Yep I have both & use both.righto who uses proving units and mcb locks? thinking im gonna need one for my assesment but will it ever get used again?
Unless you move away from the cu to test at an accessory.If you are being assessed in a house then you shouldn't need locks or a prooving unit.
I wouldn't worry to much about proving unit....hmmm i like the idea of proving on the main switch but am just worried he might be funny about not having a proving unit.
Obviously your method is a perfectly safe method of isolating your circuit..I'm also wondering if un wiring the live and neutral inside the cu and putting them in connector blocks whist working on the circuit is an acceptable (to the assessor)means of isolation,coz thats the way i do it?i see no reason for mcb locks if its done this way.
