..as above , but would fit standard B.C energy saver lamps to all remaining pendants as the Students tend not to even bother changing gls lamps when required . :(

Agi.............who ? :P a1Spark

As above. and if it was sat on a combustible surface, as appears in the piccy, at 500watt there would eventually be a bit of smoke about the place. a1Spark

Nice idea Tom1 If he did that then the existing switch position is retained and 3-core & earth could be run to each new office switch, resulting in no concealed connection dilemma. By the way it appears to me that the neutrals are joined with the old screwits type connectors, dont think...

Hi M4tty. I was just wondering where the convector heater was sited ,and its Ip rating. a1Spark

Ditto , as Andy says above. I wouldnt exactly describe Zs [Ra} of 233 ohms as good.

I would do as Apache suggests....i.e the blank plate. a1Spark

Are you sure Batty ? I think either MWC or EIC can be issued for alterations to an existing installation...I dont think it is a requirement that a new circuit has to be installed before the EIC can be used. What do others think ? a1Spark

I would go for a 4. a1Spark

Couldnt you just issue an EIC to cover the lot ? a1Spark.

Hi Volti. by virtue of the fact that I didnt mention any particular Rating Factor; must by defenition mean that I was referring to the requirement to consider All of them, that of course includes Thermal. Dont want to make an issue of it and ruin the thread so thanks for your view and your...

THanks for taking the time out in order to quote from me kme, the relevance is in demostrating that a protective conductor and a Bonding conductor can be one and the same conductor as plumber has acurately described earlier.

All with RCD protection i take it ? :Pray

Ian. Bonding is going back to the MET via the Earth Marshalling Terminal in the C.U and via the combined cpc/Bonding conductor ,as already stated....I am bothered [as you eloquently put it],about complying with BS 7671 ,and the advice given does in fact do just that .............and...

In reference to M4ttys original question, I would say that as the Earthing Conductor terminates in the DNO cut out ,then he should not tamper with it. He can either contact the DNO for advice on a possible upgrade or he can note the size on his Cert. a1Spark.

A bit more info on the subject under discussion...extract 3. Main Earthing Terminal (MET) and Building Earth Marshalling Terminals (BEMTs) An installation has only one MET, even where the installation serves more than one building. This is the terminal or bar connecting the protective...

10mm could be acceptable Noz, if Tails are less than 25mm

Did I need to Volti ? I stated : Does your method of installation require it...rating factors etc ? Would you not agree thermal insulation factors fall within this category ?

You didnt read my 1st post on the thread then SW ? ?:|
