My preference is to switch off at the mains when making some changes but on a few occasions this prolonged outage hasn't been practical and I have tested and isolated an individual circuit. In this situation, I understand that I should be using a lock and sign at the consumer unit.
Can someone please provide a recommendation on what I can purchase for this purpose?
Thanks in advance.
