Don't forget the "ringmain" cable at £65 ish per metre! It must be good, looking at the reviews! http://www.russandrews.com/russ-andrews-ringmain-cable/#reviews

What's the offer, free fire extinguisher?:D

More likely £0.12

The math at 32A only really counts if you are fully loading it, in reality a house isn't going to have fully loaded ring final circuits. The 0.4mA per amp given in the document is just really a guide in the absence of measured values.

I think you are x10 out, 0.4mA per amp.

Not that I am aware of. One way to get what you want is to keep the unswitched fused spur and add a normal pull cord but as it is a council flat you will need to get them to do it.

I set a similar unit up a while back and it was a pain, I think this is how I eventually did it: If you have and you have a roaming IP internet address use the facility on the Swann website to setup a username which is then updated by your recorder so you can access it without knowing the...

Will it power up from the battery only? It is quite easy to pop the fuse F1, I cant remember what fault it throws up tho.

It sounds like a neutral to earth short from your description. Any loading and too much current flows down the earth wire and the RCD trips. It could be the neutral wire somehow connecting to a metal back box.

The suspended ceilings I have seen will not be effectively earthed with only 1 connection, that connection will only earth one lengthways run, the runs either side will be isolated owing to the plastic clips on the cross bars.

To bond every cross bar will be an absolute nightmare!!

They may have their own point of view on things but don't we all? The NICEIC will probably allow us to use a ring final circuits CPC connected as per their guide as a high integrity earthing system but other may disagree and argue it doesn't meet the requirements of BS7671. The NICEIC took a...

Those suspended ceilings will be an absolute pain to bond properly, the ones I have seen the 2ft cross bars have plastic clips on their ends which link into the main runs!

I don't think I'd be too happy with a smaller conductor to the electrode than one for a main protective conductor tho.

This guide suggests code 2: http://www.electricalsafetyfirst.org.uk/mediafile/100126678/best-Practice-Guide-4.pdf for Absence of RCD protection for portable or mobile equipment that may reasonably be expected to be used outdoors. Code 3 for Absence of RCD protection for a socket-outlet that is...

When using lamps as resistors I tend to find it a try and see scenario, a cold filament will give a different resistance to that of warm one and different again to a hot one.

If there are sockets likely to supply portable equipment outdoors which are not RCD protected then I'd go for a C2 on this.

It was a lot more clear in earlier versions of the regs, the 17th edn has been tinkered about with too much! From what I remember the 16th edn only allowed a maximum of the same amount of unfused spurs as there were sockets etc on the ring and they were only to supply one accessory. It seems...
