If my memory serves me well,the ones I have installed in the past would flash until a button was pressed (there was a restricted time period) for you to then sequence through the neons pressing the button until you get the combination for the speed you required The only suggestion I could make...

If it was someone installing,they could look in the on site guide and then post if they are unsure If you are doing eicr then morally you should have an above average knowledge of installations I don't want to be harsh,because nobody is perfect but the post was correct to criticise in this...

You havem't gone and done something silly like connect the neutrals to the same bar as the rcbo neutral(rather than at the rcbo),then your meter indicates a problem that you are assuming is wrong polarity What meter was used

If electricians hadn't been so devalued over the years it would not be so sloppy

An earth fault in the outbuilding woud go via the CPC, MET, Earthing Conductor, 'Rod', General Mass of Earth, Next Rod, Star Point, Line Conductor, CPD, ......have I missed anything???? An earth fault in the house would go via CPC, MET, Earthing Conductor, Neutral, Star Point, Line...

With an all sweeping statement such as highlighted above Its a wonder you have not had problems getting paid with incorrect working knowlege of basic electrical information available to any practicing spark and giving incorrect information to a client via a pir ( you could end up in court) Its...

I would certainly take it the wrong way The term used was to describe a single earth conductor of an installation,where no other existed and the system type was unknown It could have been a protective bonding conductor or an earthing conductor By the way Read regulation 542.4.1 In every...

Thanks for all the replies Here is an update on the situation,with a few answers to some of the comments Why does the SP board have a 100mA RCD front end? Your guess is as good as mine.unknown,past issues maybe? So what would you have put on your cert. then mate? I would have put whatever...

A assuming there are other distribution boards within the property what are the Zdb readings of those? I did take a earth loop reading at the main distribution board and had same result.this was not at the origin of supply though

It is not my responsibility other than to inform them of their dangers that I am aware of,there is little concern on their part

I apologise if the reply gave an impression of being cocky or abrupt,it was not intended that way if that was the case or impression I gave I asked this questions because of unusual circumstances for myself I carry out installations that I know will comply normally, and was only looking to see...

Yes, I am well aware of various installations and have many years experience and 2391 etc If after giving a rough run down of the install I may rephrase the question The installation area will be for admin with a few computers etc The earthing and bonding of the main install hasn't been...

I would welcome any views and assistance on an installation in an hospital that I found today I was asked to wire and fit sockets for a ring main to some dado trunking that had been erected by a builder This was being wired from a single phase dist board which had a faulty 100m/amp rcd main...

If the circuit contains voltage sensitive devices,test 2 would be appropriate Connect line and neutral together and test between this and earth You can test any circuts that are not vulnerable to damage line to earth and neutral to earth if you wish
