On the subject of pulling the DNO fuse.

There have been a couple of reports here of the DNO confronting electricians who have pulled their fuse.


It's getting closer to home, a work colleague was doing a CU change on a domestic house last week, no isolator fitted, so he pulled the fuse (no seals present).

South Nottinghamshire.


Around 90 minutes later there was a knock on the door, a guy from Western Power was investigating a power loss at the property, reported by the Smart Meter phoning home.

He gave the sparky a talking to, and warned they are getting strict in pursuing people who do it, he said meter fiddling was rife, so any loss of power is checked out asap.

    What is the situation like in other countries? Are electricians and homeowners allowed to remove the DNO fuse?


    Has anybody actually seen an arc flash caused by shorting out a service head?



    Here in sunny Thailand there's no such animal as a DNO fuse, the wires in your incoming MCB (or fused knife switch) go directly to the meter (on a pole in the street) and thence to the local transformer.


    Want to work dead on your installation? Pull the live tail out of the meter (seals? what seals?) and do the deed. When done poke the wires back in and you're good to go.
