I disagree. I think anyone would accept that replacing a failed item with an otherwise identical item so as to bring the circuit back to the working condition it was in before the failure would not be an alteration - it is a repair.If one looks at the word alter then to replace a blown 60W bulb for a working 60W bulb would be an alteration to the circuit.
Thus, circuit is working, bulb fails, we replace bulb with same wattage, circuit is now working again and is unaltered from it's original condition.
We are talking law here, not common senseAnyone with an ounce of sense would realise you don't need to inform LABC before changing a bulb.
You can have a 60W bulb within the zones of a special location - it just has to be inside a suitable fitting.either way, we are discussing work within the zones of a special location so no 60W bulbs.
