AM2 exam Section C1 (Fault diagnosis and safe isolation of circuits)

[robert560]

Hi there,

I have my AM2 exam coming up soon and i last time failed on section C1, That is the section where you are required to isolate a single circuit (3x) and prove it is dead and safe to work on.

I know to turn off the circuit breaker and lock off and follow safe isolation, but when i am trying to prove it is dead do i do my tests in the consumer unit or do i say open up the socket or light i am trying to prove is dead and check isolation there?
To sum up, should i do my isolation for this section at the consumer unit or in the specific circuit i am to prove is dead?

Many thanks

Hahahaha shag what the F did you type into google to get that picture to come up? hahaha.

That could happen shag, true, or...the examiner might be abit fond of the young pupils testes and give him an instant pass without having to install/test/diagnose anything :38:

Like the question me and my mates always used to ask each other when we were growing up...

If your driving instructor asked you to use his manhood as the gearstick for an instant pass? Would you? Haha.

i think it was something like 'what happens to muck spreaders who plaster over spark's cables?'

by the way mate, there's only one answer to your driving test question. i'd rather spend the next 40 years using shanks's pony than take the pass!!

My method is:-
Inform all necessary persons that you intend to isolate a circuit,
You need a proving unit for your tester.
Test your tester on the proving unit
Isolate the breaker and lock off, attach notice to say circuit isolated do not switch on
Test the load side of the breaker,
Go the item to be disconnected
Test the tester on your proving unit
Test the item to be disconnected

If all is OK and safe then proceed to disconnect

To test at the breaker you'd have to take the cover off the board, meaning the whole installation would have to be turned off before removing the cover (electricity at work regs etc). Prob not what they are looking for.

I had to do the Light, Motor and entire board.

Proved dead at the actual light and the motor, remember to test all switch positions of two way/inter. Entire board is just the 10 tests on the load side of main switch.
Remember to reprove indicator and don't give the examiner the key
