Replace and repair. Some of the old system will stay. Some will be replaced and repaired.
Can you correctly identify all components and connections of a circuit by method of testing or otherwise? In doing so can you identify or recognise anything wrong or dangerous with the circuit? You cannot assume that what's currently installed and you think should stay is OK, and you need to check it before starting work.


And as for me being competent ...well even qualified spark's are not competent.
Some are not as competent as they should be. The vast majority are far more competent than you.


And yes. i am only repairing and replacing.
  • For a circuit to supply a given load, how would you go about deciding what cable and protective device to use? (No, you can't just copy what's there because it's going to become your responsibility and what's there might be wrong.)

  • Do you know which circuits can be ring finals and which cannot, and what the advantages and disadvantages of each are? (No, you can't just copy what's there because it's going to become your responsibility and what's there might be wrong.)

  • How do you calculate maximum demand and how can diversity be used?

  • Do you understand how the way in which cables are installed affects how much current they can carry? (No, you can't just copy what's there because it's going to become your responsibility and what's there might be wrong.)

  • Where cables need to be joined, how should this be done / not be done and in what circumstances are different methods acceptable?

  • Can you identify extraneous conductive parts, and do you know the requirements for main and supplementary bonding of them?

  • Which circuits should be RCD protected?

  • What about the testing that you should do on your existing installation before you change the CU, if you want to be sure of avoiding grief from new RCDs tripping?

  • And what about the tests you should carry out after the installation? What sequence will you do them in and at what point will you energise the installation, and for each test do you know what is being measured, why it is important, how you would carry out the test, and with what equipment, and what sort of results you would expect to get if everything was OK?


More too the point i have nice helpfully people like yourself too help me out if i get stuck.
The thing is, rewiring a house, installing new CUs etc is not a trivial job, and I can assure you that it involves knowing far more than you think it does.

Asking questions here can be a useful part of a learning process, but they are not a substitute for proper structured studying. The key term there is "learning process" - you cannot learn all the things you need to know just by asking questions here. It isn't structured enough - it won't provide you with a way to progress where each step builds on what you learned before.

You can't carry out a job of this magnitude by asking whatever random questions happen to occur to you. What if you get something wrong because you have no idea your knowledge is wrong? What if you miss something because you simply have no idea it even exists, and just don't realise you don't know it?

so its rocket science?

And cannot be done?

Ill take that on board.

I have a friend called google, a sparky part p reged(300miles away)

and you....What could go wrong. lol

Seriously the only concern i have is testing/measuring before and after.

i am sure i can google 99.9% of them.

As i said its the testing, however some sparks don't even bother doing that properly.

Its irrelevant whether i know the answer, it is more important that i can find out. As long as i have the aptitude to understand what i am doing and why then its possible to do myself.

if and when i come across something i do not understand then further information can be sought.

Just because you are not qualified or recognized by an association does not make it impossible for you to complete a task in a competent manner.

Its not rocket science. It has been done successfully by many DIYers before the existence of any trade bodies/association.

Even the testing is not difficult, however understand why and the readings and the fault finding (if any) i would think is the hard part. In saying that many sparks install the same method of wiring over and over, never testing properly. All because it worked before.



May i ask why you are so negative in many of your posts?

And just out of interest. As i am not as knowledgeable as yourself and still on a learning curve could you answer a hypothetical question.

Parts of the system currently in the house has has been diyed in the 70/80's. Has some old wiring from the ark.

Why would a direct replacement if done correctly be anymore dangerous than it already is. eg new CU direct replacement for new wire.
Even though mains sockets are radial. I realize the loads put on, in 19 oatcake are allot less than in this day and age(just forget that for a moment and do not consider it in the equassion)

The system has been in place for well over 40 years and some of the older circuits must be nearly double that.

You're a clown - go away.

Indeed it does not.

BUT YOU MUST ACQUIRE THE COMPETENCE NEEDED BY ACTUALLY LEARNING ABOUT IT BEFORE STARTING, NOT JUST BY GOOGLING ONLY WHAT YOU THINK YOU NEED TO KNOW ABOUT ON THE BASIS OF WHAT YOU KNOW YOU DON'T KNOW ABOUT.

In saying that many sparks install the same method of wiring over and over, never testing properly. All because it worked before.
And you know all about the working practices of qualified and competent electricians, do you?

The fact that you say that just shows that you have no idea what testing is, what it does and why.


May i ask why you are so negative in many of your posts?
I'm not.

I am realistic about the knowledge needed, I am accurate in my observations about the lack of knowledge that so many people have, I am well meaning in my advice to them to learn or use an electrician and I am helpful in pointing them at a variety of resources they can use to start learning.

And I am intolerant of people who then get all bent out of shape because those observations and advice were not what they thought they should get.

I didn't say it could be more dangerous.

But it could be as dangerous, and therefore not compliant with the Wiring Regulations, and probably illegal.

OK lol its lasted in excess of 40 years. its repair/replacement it does not have to conform to new wiring regulations. i would say assumming it is was dangerous its going to be safer lol.

or have i got it wrong.
