I'm looking Forward to the two rodneys down the pub, so it's good night from himLooking forward to the annual Xmas rerun of ‘Morecomb and Wise’ Christmas special.
Didn’t even see that dent/damage.Glanding the cable to a metal fused-switch like the Wylex ones would have been far better, then double insulated tails to the meter.
It looks like the "filler" insulation around the 3 cores has been clamped or similar - wonder how that dent happened?View attachment 112405
Only Fools and Rodneys???I'm looking Forward to the two rodneys down the pub, so it's good night from him
sliding under the table.
Morecambe........which one is buzz?Morcombe and Wise, Two Ronnies???
Might I direct you fine gentlemen to another thread….
OK so I was clutching at straws but it is the kind of thing examiners include solely to stop people getting full marks.mmm! not so sure Id agree it as a non-compliance, Isn't there a passage in the regs that says "alternative 'systems/methods' etc shall not be precluded as long as safety isn't impaired" (or something like that as I Don't have regs book to hand )?
Alternative wording/pictograms hardly impairs safety and message is clear enough!
They replaced meter tails with SWA making the MET remote.I am no expert on the regulations but wondered whether the sixth item is that the main equipotential bonding is done remote from the cutout location.
The according to the book ‘rule abiding‘ installation should have the earth conductor from the incoming N in the cutout going only a short distance to the main earth terminal bar, and then from this bar runs a cpc conductor to the dist boards, and separate EP bonding conductors for say water and gas connected also to the bar as in this figure.
With this scheme the cpc wiring and EP wiring do not share one conductor which might be considered a possible single point of failure. Just musing….

Polarity is incorrect from the meter to the consumer unitJust spotted there is a wiring fault in the figure I copied and posted in my #34.
I'm not sure the polarity is wrong, but probably the tails are incorrectly identified.Polarity is incorrect from the meter to the consumer unit
You are correct, Marconi got his crayons mixed upI'm not sure the polarity is wrong, but probably the tails are incorrectly identified.
Many meters have L-N-N-L terminal lay-out.
Whichever though, its not correct.
If only it was just my crayons......You are correct, Marconi got his crayons mixed up
I'd suggest the opposite.I am no expert on the regulations but wondered whether the sixth item is that the main equipotential bonding is done remote from the cutout location.

This is why experienced engineers should be making the regulations not brain dead office staff. Surely a separate isolator in an enclosure and the extra time required to fit it would add up to more than £6?!The feedback- it was refused as it would cost an extra £6 per meter.
