jb-eye Posted December 4, 2004 Share Posted December 4, 2004 there is nothing wrong with using a 100ma rcd as a main switch, its considered as supplementry protection against indirect contact where the main form of protection is EEBADS (earthed equipotential bonding for automatic disconnection of supply) and it is not a requirement to protect all socket outlets with a 30ma rcd, only the sockets that could supply portable appliances which could be used outside, however in a house its normal practice for all socket outlets to be rcd protected. using the correct size and type of overcurrent protection should provide a 0.4s disconnection time i.e. a mcb to BS EN 61009 (mcb= miniture circuit breaker) hope this as cleared the matter up! 33658[/snapback] Why are we looking at EAW. this will only refer you back to BS7671. MCELEC has answered the question above. To further clarify external use is a special location and therefore requires a disconnection less than .4s as do other special locations. If the system has a design incorporating 100ma rcd elcb the special location can have a dedicated 30ma protection after the 100ma switch. It is now recognised that any downstairs socket outlet could reasonably be used to feed external apparatus and that’s why we do this. Jef Customers!

Guest IM_Alarms Posted December 5, 2004 Share Posted December 5, 2004 I was contesting Whoosh's arguement with Lurch, that ALL sockets must be on a 30mA RCD because the EAW regs said so !!! The EAW regs do not refer to BS7671 any more than a suggestion that if you comply with BS7671 then you will probably achieve compliance with EAW regs.

Woosh Posted December 5, 2004 Share Posted December 5, 2004 Here ia a link to the Goverments website where the Statutory document is published. I know it does not apply to domestics but we are all talkinga load of waffle about nothing. ALL DOMESTICS REQUIRE A 30MA RCD TO PROTECT THE SOCKET OUTLETS END OF STORY !!! THE END !!! http://www.hse.gov.uk/electricity/faq.htm Link to comment Share on other sites More sharing options...

Not all domestic sockets require RCD only those as described in mcelecs post YES YES YES of course their is nothing to stop you protecting them but dont try kidding anyone that this is either a reg or a requirement of EAW it dont wash.Jef Customers!

Woosh Posted December 5, 2004 Share Posted December 5, 2004 I assume that all the people voicing thier opinions against the statutory documents and non statutory BS7671 ARE qualified electricians who hold City and Guilds 2391 ?? Awating your response IF THERE ARE ANY. Link to comment Share on other sites More sharing options...
Woosh Posted December 5, 2004 Share Posted December 5, 2004 I have decided that if other people wish to sign documentations for electricial work THAT IN MY OPINION is not meeteing the regulations that is up to them. Furthermore I will have to consider further wether or not to post here again, I was under the impression that this was a friendly place for electricians and installers (SSAIB) to meet and talk. I feel that SOME people are unpleasant and instead of just ADMITTING that fitting a 30ma RCD in the consumer unit procecting the sockets is the best method for customer safety they and try to nitpick that ONE socket with a built in RCD is the way to go. I was only pointing out in MY original reply that the poster should be aware that IN MY OPINION a 30ma RCD should have been fitted to protect all sockets.

morph Posted December 5, 2004 Share Posted December 5, 2004 Keep your Hair on, forums are for debate and due to there nature, you wont always get an answer you want to hear or even get someone to agree with you. The bottom line is that there are lots of "Qualified People" on these forums whether they are DIY or Professional doesn't really matter, what does matter is if they are able to apply the quallification and the knowledge gained from it to a pratical use in the real world. Yes you may be a Qualified Electrician and yes, you may hold the City and Guilds 2391 Inspection and Testing certificate, but to start to go on one about what you feel the installation should have is purley conjecture. You should consider the type of property, the location of the sockets, the age of the property and most importantly WHAT eddition of the BS7671 the installation was installed to. To say that the installation doesn't comply with the current regulations may well be true, but to imply that his installation is not safe, based on a couple of his posts is not a good move, as this will always start a debate. In my opinion the guy should have been advised "Not to touch the alarm or the fuseboard" and to seek professional help "an electrician" We all as responsible people should not seek to advise people of what may cause a fault with an RCD, as they are all installed for a reason whether they be 30ma or 100ma, if they trip there is a reason and this can only be investigated by a competant person. There are lots of people on here with electrical qualifications, but some of us would get the full facts before reccomending a solution. ELECTRICITY KILLS and we should all remeber that. The rights and wrongs about the RCD should be debated in the trade forums, not in the public ones where an unsupecting DIYER may act on the information. The forums are great place to debate our industry, but remember you wont always like the answers, but that no reason to throw your toys out the pram.
