nothing like being thrown a curve ball

So what about safe isolation for a distribution board change, how many people would test all the outgoing cables as well as the incoming supply?

You don’t have to test all of the outgoing cables separately, just test with all breakers and main switch closed.

You didn't follow safe isolation, electrocuted your son and then electrocuted yourself........

Everyone's perfect on here when it isn't them who made the error.
In fairness I'm pretty certain that many would just switch the light on, see which MCB made it go off then just crack on, in fact a one cable light fitting job would be 'safely isolated' by many just by turning the switch off.

If the meter fitter had checked their Martindale pre and post job, it would have alerted them to the mistake they made. Not following what is a very basic and simple procedure is inexcusable really.

Also, visually checking and tracing cables after the job (which should have been tagged and identified before removal) takes 2 seconds ... and there are usually only four to look at!!

that is a lesson learnt had voltage indicator on l+n when switching off tbh I didn't check between l+e for some reason on this occasion but as I said season learnt
anyone else had this issue after a meter change

And even if you had it wouldn't have identified that there was a problem as the n-cpc had the voltage

I had a DNO engineer out a couple of moths ago to remove a meter and install isolator. He reversed the tails but checked polarity on completion and corrected mistake.

An interesting time concept... was it the a month was too short and moths generally live for 5 weeks??

Didn’t you know there are two months to the moth?

Safe isolation pull main fuse.....

Not much use if the cut out is reverse polarity though?

They weren’t electrocuted or they would be dead...they both received an electric shock.

how many cutouts are reverse polarity though?
the DNO have trained jointer teams doing all work after install, the meter fitters not so much. Having seen a jointer team working there wasn't much chance to make an error.

Very true when using concentric cable but I’ve seen 2 reversed when fed from over heads as the cables are generally the same colour and if the cutout is mounted upside down to accommodate the cables entering from above confusion does arise with the cut out fuse now on the right.

I think there would nave been other issues that would have been noticed like the electricity company paying you as the meter was running backwards............

DNO reverse polarity is as rare as hen’s teeth.

Metering side: more likely. Obviously, you’d still be isolating everything if you did happen to pull the fuse. Admittedly, it’s usually the customer tails that are reversed than the cutout side.
