At present we use 16th edition until June 2008 with additional tests and some additional requirements laid down by the engineers which surpass BS7671.

We dont use the codes, we just report on what we find and the engineers make the decisions. I will look up the codes in BS7671. Its a while since I had a good bedtime book to read. Just done the 17th and to me there aint much changed.

I do test against the current regs, but the regs are not retrospective, so if something was installed to the 12th edition and has not been touched since then there is no requirement for remedial works. The fault codes you mention are NICEIC, which is not required by our system. I report on...

I realise that but when I make comments on the installation, the engineers (who control the works), need to know whether any action is needed to remedy the circuit or not.

That is all I know at the moment. That is the reason for doing the course. If I knew all about it then there would be no reason to attend. I am not going into politics here or anywhere else. I have my view to which I believe I am entitled.

when testing older installations (since the regs are not retrospective). I test lots of old installations for a large LABC and report on their condition.

Sounds like the spark is profiteering. Either do what BAN says or have the CU replaced with a new split load CU.

I got that one, and it is probably the best (not mentioning Carlsberg)

You also need to consider whether the existing installation is TN-S or TNC-s, as you dont want to be exporting a TNC-S earth path to an outbuilding where you could be introducing a potentially dangerous potential difference to the shed installation.

doing my 17th edition upgrade next tuesday. From what I have read so far, most of it is just about moving bits of the regs around to suit europe with some add ons about mobile theme parks and markets and temporary installations. (I love europe since the introduction of temporary charging of VAT...

Just as a future reference, you can downrate fuses without any problems, it is when people uprate fuses it can become a problem. i.e the factory owner who sticks nails in the holder to get the machine working (cos it works ok dont it)

A good book is BS7671 wiring regulations and Guidance note 3. NICEIC also produce a book on testing and inspection. The problem is I have found is that when testing jobs from the 1940's, I also have to know the 11th, 12th, 13th, 14th, 15th, 16th edition regulations (as the regs are not...

what is the rating of the shower?

thanks

I know this probably sounds a daft question, but here goes. I have got my new double glazed sealed units but do I remove the black tape from around them before installation. Is it just to prevent damage during transit or is it actually part of the unit. Sorry if this sound daft

I would suggest the client to use a competent electrician. P Clifford TMIET

If you had your car repaired at several garages would that also make you exempt from an MOT?

test each leg of the ring individually. firstly test half of the circuit. then half agan until you find the fault

the work will need to be installed to BS7671 and the Building Regulations. By following these codes of practice the system will be safe and comply with the relevant rules
