supplying garden shed

[Doc Hudson]

if you install a cu for the shed you will have to break the earth and put it on a tt system,

it clearly states in the regs about breaking the earth???

Incorrect on both counts. Unless you define what you term as "breaking the earth" and what the earth arrangement is at the incoming house supply and also confirm what extraneous conductive parts are in the shed. Remember the OP states that the house supply is TNS.

where?

I have been studying this very thing all afternoon and have an old copy of GN8. By breaking the earth what he is referring to is where a PME installation is extended in to a shed unless you can comply with all the PME requirements in terms of size of earth conductor and any equipotential bonding conductors you need to TT the shed and ensure that the supply feeding the shed is only earthed at the installation containing the assocoated protective device. The shed end is earthed on to the rod. This used to be reg 542-01-09 and is now reg 542.1.3.3. I know what he means. I think some people refer to this as exporting the PME a term which I hate. Just to be clear, this only applies to PME not TN-S.

The argument about extension leads was a little tongue-in-cheek. Accept PC electrics points. tbh buggering about with extension leads is entirely DIY territory. I don't use them for anything other than charging up my batteries or plugging in my work light.

cheers lads for all your advice this being my 1st shed job its been much appreciated.i like the idea of spurring off to a dpsfcu then feeding the shed with swa then spurring off socket in shed to a 2nd dpsfcu with 3a fuse for the lights simple, cheaper and at end of day its safe. i probably wouldnt have got the job by suggesting 2 small cus at either end would of cost abit more and probably alot of hassle. i will be returning to the property tomorrow to price the job up so will ask exactly what the power will be feeding thanks everyone

ps how do i get my elecsa logo under my name to stop the whingers saying " are you part p" or "are you an electrician". its a forum people come on here to get advice, give advice and generally help each other but on alot of the posts right through the forum you always get the whingers. now i have been given some cracking advice about this shed job which now i wont ever need to ask about again its logged into my brain for future reference for which i am most greatful, am sure the whingers had questions when they started out RANT OVER

When you discuss the power requirements, if they do not know, an alternative is to give a couple of price options such as

Was that final comment really necessary Doc? I don't think your response to rins was really warranted. Please try to calm down. Forums are renowned for techy repsonses and I saw nothing wrong with rins. Thank you for your concern.

Yes it was as posting irrelevant facts can cause more confusion to others. Especially when a member is already struggling with simple concepts, raising other non related items carries little help. Clearly you disagree which is your entitlement. But basic wiring to a garden shed from a TNS supply does not need a debate on PME exporting earths. If you wish to discuss this matter you can start your own thread rather than hi-jacking someone else's.

Doc I was referring to comments made by Iselectrical.

By all means moderate but please don't dictate. Thank you.

As a moderator Doc Hudson can dictate the way the discussions are progressed, off topic discussions only confuse the discussion and serve no purpose.

I am not defending the Doc, just trying to explain that moderation of topics can sometimes have the need to dictate the way it is conducted.

You have made some very good posts, and is one of the reasons why I sent you that PM, I do think after time you will prove to be a very good member of this forum, I just hope you do not let me down, or more to the point yourself down.

Doc I was referring to comments made by Iselectrical. By all means moderate but please don't dictate. Thank you.

All members are entitled to give opinions on any post just as much as any other member, irrespective of post count, duration membership, member status, moderator, forum sponsor etc. Please do not dictate how any other member is or is not allowed to post. You may be best to clam down and read the posts in context with the OP's question that was asked. Rather than trying to hi-jack someone else's thread for you own private moans about how or how not the forum is run. I am sure Iselectrical is capable of backing up his own posts without needing your assistance. I still consider them not relevant to shed wiring from a TNS supply. We call that an opinion not dictating. I shall remind you that Admin is more than capable of removing moderator status from a member who they consider is not helpful to the forum, it has happened in the past and no doubt it could happen again. Now please can we keep discussion on topic, or have the respect for the OP and start your own discussion on a new thread. (Just in case you are still confused, again that is guidance, not dictating!)

Another thread becomes an excuse for members to try and take the high ground in terms of knowledge and quoting regs numbers to completelty irrelevent points. Sometimes the advisors need to relax and just answer the bloody poor souls question. And stop banging on about part P, notifying work etc etc. Safety is obviously paramount but understand that people asking for advice are more than likely going to do the job whatever you say so best give them as much info as possible to keep both themselves and/or those whose work the're doing safe. By all means say it should be done by a qualified/registered contractor but stil give your knowlegde because surely thats the reason most of us are members of these sites (other than those who just like to brag and preach) to both give and receive information/wisdom.

Surely part p needs to come into this after all as not many customers know about it it needs to be pointed out. This is  for anybody searching on open forums for advice and thinking about doing the job themselves.   They need to realise you cannot now put power to an outbuilding without either getting a registered person to do the work or notify the council so they can send a qualified person to check your work. As for people taking the high ground. I really have not got time to read back through an eight month old thread to see what people have said.

  I see this is your second post the other being about your exam results. Well I am not sure why you are getting so aggressive. I can tell you it costs me around £1200 a year to be registered to do the work legally so why would I want to tell anybody to do the work not by the book and probably not to a safe standard.

Hi all,

"So, why are 4-gang 6-gang or even 8-gang extension leads made? They only have a 13A fuse in the plug. Is this poor extension lead design?"

Best address this question to the local fire brigade. I have seen LOADS of 13A sockets outlets and plugs well and trully burnt out, and/or the plug "welded" into the socket. The 13A fuse did not do much of a job protecting them!!!!!

[alfiesmudger]

Sorry batty, didn't mean to sound aggressive, just seems a strange way to conduct a question and answer forum. Every question could be answered either "if you don't know your not qualified to do it" and "if your not qualified you don't comply with the regs/part p". Not sure what me only having two posts has to do with anything? Surely even someone with over 9000 posts has to start with 1?
