When to rewire house?

[skipdiver]

Yes i agree with what you say Alan.Obviously i know regs have to be followed and i think the earth bonding thing happens all the time but for your average punter it's a minefield.Even the sparks i come across at work don't agree on interpretations of part P.

I have someone coming round once i get the roof on my workshop,so will see what happens.

I have a sparks in the family but he's married to my niece and they're not my favourite people.

I haven't personally seen PVC wiring deteriorate other than where a faulty socket has caused overheating.
With the passage of time loosening of the clamp screws appears to be the major cause of problems.
As regards running PVC cables in conduit I would point out that PVC when damp produces hydrochoric? acid.
That mistake cost a number RAF pilots their lives!

I have seen lots of pvc cable run in both plastic and metal conduit,I rewired my own house about 18 years ago and an electrician advised me to use plastic conduit,are you saying that this is wrong.

Thanks all for the very helpful replies.
It looks like `When to rewire a house` raises more questions than answers!.
My own industry (Gas) has just as many if`s, why`s and maybe`s as the electrical and even now you can have the situation where two qualified gas engineers can arrive at different decisions :shock: . Only the other day someone told me about a well known and respected gas company condemning one of their own earlier installations !!. I`m afraid when it gets to the point that a qualified and renowned firm starts condemning itself it does`nt bode well for the unqualified amongst us. Today I have spoken to six people down my daughters street none of whom have rewired but just replaced the sockets/switches and after checking her installation myself I am happy to do the same. No doubt someone could justify a rewire after ten years quoting `What if` but I think common sense must prevail. A thought occurred to me:
We are constantly told what disgraceful and wasteful beings we are using supermarket carrier bags, and plastic containers which lie dormant in landfill for hundreds of years because they DON`T degrade so WTH does happen to plastic ? does it degrade or not it can`t do both??

Ps I know its not carrying electricity but you get my drift :wink:

No! In metal conduit. PVC moulding tools are normally chromed because of the corrosion problem.

I had a prime example of this several years ago with gas fitters.I did a gas board fitter a favour so he said that if I needed any gas fitting doing he would do it cheap,sometime later I was buying a new canon caress gas fire from the gas board showroom, and he fit it as a favour anyway not long after it kept going out so I rang him and he told me that he had found out that there was a design fault with this fire and that if I rang the gas board they would send a fitter and as soon as he saw the fire he would know that it needed a replacement part with a hole at a slightly different angle.Well I got home one night to find a fitter had been checking the fire for 2hr and he told me that there was not enough gas pressure,so I told him that I was told there was a design fault with this fire to which he said was rubbish and that I needed all the pipework renewing and left.I rang the guy who fit it and he said that the other guy was talking rubbish and that he would sort it and a few days later another fitter came and changed the faulty part in about 10mins and it is still working well.

well it depends on the molecular bond/chain that is used in manufacture, but I can tell you for an absolute fact if you hang on to a modern flimsy shopping bag for 6 months it will turn to dust when you try to pick it up. Proved it to my daughter the other day who at school is still having this mis information spouted at her regularly. I probably have a few more ready to fall apart in the workshop now tucked away with a few bits an bobs in...they don't even have to be in UV sunlight. It's one more bit of mis/dis info that is propogated. Other plastics may differ of course.

I'm told by the sparky at work that after July the first all new socket outlets fitted will have to be of the integrally fitted RCD type, this is going to be costly, this complies with the 17th edition, he said. :shock:

 

[Digit]

Not so Rich the Regs state that all circuits must be protected, that includes lighting.
At least that's how I read them.

Additionally, all socket outlets rated at 20A or below within a domestic building will require 30mA RCD protection*. This means that all ring main circuits from consumer units will either need to be fed from the RCD side of a traditional split load board or have individual residual current breakers with overload (RCBO) ways.

Which shop was it from?

 

[Rich]

I may have to eat humble pie here, I'll return to this on Monday when I will ask him about this, he has just passed his 17th edition test, my manager also echoed the same about RCD socket outlets.

I sympathise with both the fitters who were probably doing what they thought was right given the available info to them by their bosses (don`t get me started on that either :x ) Do you know as a gas transporter who I work for we presently have to provide (at present) 21mb +/ - 2mb so 19mb or 23 mb is supposed to be acceptable at the meter BUT some boilers lock out less than 20mb so whats the score there?? One hand not knowing what the other is doing methinks!.

Alan
Yes thats what we are up against, though not sure how I can check the molecular bond/chain of my daughters wiring but I`ll give it a go, just have to dig out the old mass spectrometer and electron microscope out of the shed :lol: .

Rich
Are you like me sick and tired of being told what to do with your house/car/job/household waste etc etc to satisy some jobsworth in an office trying to justify his job? AAArgh must lay off the red meat :x

Steve, I'd really like to answer you on this one, but I dare'nt, I've been censored too many times for speaking my mind, having said that, have you noticed how quiet the forum is without a bit of contemporary chat about everyday life, but I do agree with your comments and my answer is YES, YES YES!!!.

BTW Have you seen the price of red meat? I have'nt had a sirlion steak for weeks now, even rump is a crazy price, bacon chops are the highlight of my week at present.

I think he may have been interpreting the rules and deciding for himself that they are referring to installing a new socket as a spur on an existing unprotected ringmain...or else he's talking rubbish and misinterpreting the rules.

Was it Tesco or Asda, perhaps?

 

[Woody Alan]

Jake wanted to know

Was it Tesco or Asda, perhaps?

I have no particular alligence I have had bags from both that do it, I presume that's what they are now designed to do.

I am just looking at a co-op shopping bag and it says,from the date of manufacture,the plastic will start to degrade in approx.18 months time.The whole process will take about 3 years.See bottom of bag for date of manufacture.
