safe isolation for work on lighting

[Ric79]

My manager is telling me that I can safely change a light transformer by switching the lights off at the switch. I thought the light switch wasn't suitable for isolation. And also if the lights are on further on in the circuit can there not be a residual current in the neutral. What are your opinions? Thanks in advance.

what do you think

aye sound good , bit of tape over the light switch , joke joke

You should be isolating the whole circuit in such a way that it cannot be switched on whilst you are working on it. You should also have an approved voltage tester to prove the circuit dead.

Then print it off and show it to your boss.

Ric, there's a good chance that if you take this clown's advice you could die. There is no substitute for the proper safe isolation procedure.

The question is far too open ended! It depends on a number of factors but the answer to your question as it stands is yes/no/maybe

Your write about the neutral any load on it and may bite you

If you are the one carrying out the work then it is your responsibility to isolate it properly regardless of what any other numpty tells you.

I have been working on a lighting circuit (safely locked off at the CU) when the customer has come in and tried to turn the light on at the switch "So that I could see what i was doing"
The moral of this this story is SAFE ISOLATION.

Why would you consider not isolating the circuit properly???
To be competent at your job you need to know the basics safe isolation being one of then!!!!!
