I'm competent enough imo and have all the tools required to do the job.
The tools required would include:-

RCD test meter
Low ohm meter using at least 200ma i.e. not a multimeter
High ohm meter using at least 500 volt again not a multimeter
Loop impedance meter
Prospective short circuit current meter

These are normally combined into three units cost around £750.

You should also have a voltage tester and proving unit although in most cases there is no isolator so it would require the supplier to draw the fuse. See issue 16 Spring 2010 of SwitchedOn.

Depending on a few factors but with a TT system you may also need an earth rod tester so looking at £1000 to buy test kit. OK you may have all this gear but I suspect you didn't know you needed it.

The TT system does need items before and including the first RCD to be double insulated type. I can see point in up to a 300ma S type RCD feeding a array of RCBO's but the more common way would be two 30ma RCD's.

The LABC charges of £100+ mean it is hardly worth DIY'ing this type of work unless part of a larger project and already covered in the LABC charge.

There are four grades of people as far as electrical work is concerned.
Highest is Competent
Next is Skilled
Then Instructed
and finally Ordinary person.
They are not defined as having passed any exam but in the main the insurance companies will require a C&G2391 or 2392 to be considered competent for the work you are doing. As you must understand the dangers in using instruments like the loop impedance meter and insulation tester which if used incorrectly can raise earthed items to 230 or 500 volt above true ground.

I have not seen how the LABC work with Instructed persons as I am competent. But since they are responsible for safety they may well require the supply to be disconnected then they will allow you to do work and then all tested before the supply is re-connected. This could mean days not hours without power. It would also mean calculations as direct reading loop impedance meters need power to work.

You may have all the skills required. But if so, why ask the questions?

You make it sound like rocket science. Its not. Testing equipment is not part of the tools needed to carry out the installation. My mate has all that gear though.

Being skilled and having knowledge are two different aspects to just about any trade as you should know.

Will he still be my friend if my home burns down and he's in the clinker and struck off. Yes he will

Your insurance company will refuse to pay the claim. Who will pay for replacement of all the things you will lose ? Who will pay for you to buy a new house or rebuild the burnt out one ?

Or if you rent the house who will re-imburse the land lord for loss of property and income. If he is well insured then his insurance company will compensate him and then go for you in court to recover their losses from you.

One of the things you may lose as a result of in-competent and falsely signed off work is the life of a loved one.

You make it sound like rocket e your science


To someone of your low IQ it is rocket science. That's why you can't write a reply that makes any sense.

Go away and have your bedtime hamburger & milk.

Reading through the archives has quite a few arguments by the so called professionals.
If they were building rockets not many would ever leave the ground. :LOL: :LOL:

(ps.read above over and over and slowly until it makes sense)

I can see why you are unemployed and unemployable.

12 double sockets in a tiny garage? You got to be kidding. :rolleyes:
Anyways I would have diyed that little lot for a few hundred quid.
As for the signing off, tell the rip off sparks to go and stuff them selves.

FYI - he has the same attitude to boilers: //www.diynot.com/forums/viewtopic.php?t=253758[/QUOTE]


Yes, another subject which is beyond his low IQ
