All, Thanks very much to all who have commented and offered advice. Cheers. Chris

My copy of the OSG guide arrived this AM, hallelujah! I just love table 7.1 This thing is like having all you guys in handy ring-bound form and none of the 'old' forum posts muddying the waters! :D

Yes, but my darling wife prefers the ring of the Byron Underdome Bell http://lib.store.yahoo.net/lib/myknobs/underdome.mp3 Haven't sounded them (LABC) out yet (pun intended)

Wooshzz99, Yep, I did a quick costing of a modifed layout after listening to the comments from you guys and decided that all RCBO was probably the way to go:

Calm down Wooshzz99, what is it that I, or anyone else, is propsing that doesn't adhere to this? The only circuits not on an RCD/RCBO are the two radials to the two sheds, these will exit through the house wall just below the CU (surface mounted) and then SWA to the sheds. What am I missing...

Liam, The item I was looking at was http://www.tlc-direct.co.uk/Products/MK5621.html, text describes it as: MK Sentry 21 Way Insulated Enclosure - for up to 19 MCB s Accepts 21 One Module Products or 1 Two Module ( Main Switch or RCD ) and 19 One Module Products The...

Thanks for the comments so far all. After revising the layout following your advice we get: Non RCD side: Bell xfmr 6A RCBO for smoke alarms 40A RCBO for cooker 16A RCBO for immersion heater 16A MCB for 2.5mm radial circuit to big shed (2.5mm SWA external/underground, RCD socket in...

Hi widdler, What's the argument for not having the smoke alarms on their own dedicated RCBO? Without any RCD protection, and requiring their own circuit, wouldn't it be much more work to comply with regs whilst routing the cables?

Thanks flameport, It's not that I don't want smoke alarms, there are currently two battery powered alarms installed, I didn't realise that I needed to replace them with mains powered/battery backup versions during a re-wire, thought that requirement only applied to new build having taken a...

Thanks ColJack I'd been told by a work colleague that that requirment only applied to new builds, not rewires, so I hadn't looked into it, I will now. Thanks

Thanks Liam, As I understand it, the prescribed max lengths / floor areas are to enable installations to be carried out without the need for all the calculations, i.e. if you stay within these values you are sure to be within the safe limits without having to do the calculations? I always...

Thanks nozspark, I'd noted that one

Thanks for the reply widdler, My wording may be a little misleading here, I have two sheds and am proposing one radial for each. Could do, it's a gas boiler with no electrical heating element, from what I've read it's the heating elements e.g. electric cookers, immersion heaters etc that...

Hello All, I'm trying to determine a sensible consumer unit config for my victorian property, the old wiring was a real dogs dinner and has been completely removed for peace of mind. Being a fairly competent type I intend to do most of the rewiring myself, get my electricity supplier to move...
