What codes for these?

House wired around 1995
What recommendation codes should the following be-

1 . Meter tails 16mm should be 25mm
2. Main Earth 10mm should be 16mm
3. Bonding to water / gas 6mm should be 10mm
4. Water / Gas bonding connections not within permitted distances of main valves. Randomly placed
5. Circuit schedule incorrect

If there is no imminent or possible danger to arise from the last one then I'd say all code 4.

16mm tails are ok if the service fuse is 80A or under. 10mm main earth depends on adiabatic , knowing the pefc. bonding conductors min. 50% of main earth conductor, so if 10mm is ok for main, 6mm is ok for bonding. code 4 on the position of the bonding connections. easy to amend the circuit schedule. all above are my personal opinion. others may correct me.

I am with Tel on this one.

Are the bonding connections "as near as practically possible to where the service enters the property" even though they are too far away? if so no code in my opinion.

I would be pleased to see any bonding at all, i see more without than with. But seriously being bonded is better than not being bonded, and how much longer will it take the fault current to travel the extra few feet if the need arises. The application of common sense sometimes needs to prevail. I always ask myself "Is it dangerous?" or "will it cause a problem".

I always have to laugh when run through the inspection schedules and "Conductors correctly identified" I see about 1 in a 1000 light switches which have "Conductors correctly identified". And i will be honest i overlook it, why you may ask, well if you are buggering about in the back of a light switch and don't understand why there are red/blue/grey/black and any other combination of colours in there, then you shouldn't be in there in the first place. I would look a right t**t putting a quote in for fitting sleeving to conductors in switches, and i'll be buggered if i am taking it off to sleeve it cos you can put your house on the fact that all the connections will break cos some halfwit has wired the switch wrong way round and given it a really good twist to get it right way up.

Rant over,

i've never understood the need to sleeve phase colours anyway. RYB all were considered as "live". now the mud colours are the same. sleeving a black sw wire, yes ( or nowadays blue ). any sparks knows that any cable colour connected into a switch is not a neutral, and, as you say, anybody doesn't know this, shouldn't be let loose with a terminal driver.

Re the meter tails, but you don't say what size the main fuse is but not sure that its even worth noting 16mm to 25mm

Last time I noted an issue with tails was when I found a 100A fuse and 10mm T & E cable - noted it as a code 2 and the owner has done nothing.

I couldn't agree more

I have come across this quite a few times, it seem very popular on a council estate full of flats near me. Most if not all are now privately owned and it is now the owners who are getting the fallout when they need work done. One or 2 of the ones i have seen will need major surgery to get any proper sized tails and an earth in.
