Hi all

I've recently been foolish enough to buy an 1850s house. Its listed, and so is the existing wiring, bloody good job conservation don't include that as part of the things that can't be touched. Un-eartherd metal conduit with two red canvas coated rubber conductors that break up when you bend them so you can see the cores inside anyone? And thats the safe stuff....... Can I keep all those quaint ceramic toggle light switches .... ?

Moving on from this if we may, here are some probably silly questions about safe zones.Very entertaining and interesting reading on the subject so far !!

There is at least the luxury of a lot of room to work in the cellar; nothing but the bare 7"x3" joists of the ground floor that are 8' 6" above the stone flags beneath. Ignoring the many rotted beam ends and numerous toads hopping about....

From that:

1. Can all the cables from the CUs to the rest of the house circuits be run in suitably earthed steel cable basket (2" mesh) bolted to the joists in the cellar ? i.e. "Yes big nose, thats surface mounting!!"

2. If _PART_ of a cable is outside of a safe zone, (for example to route around some object that can't be drilled through / mashed / bent / looked at funny / farted near ; see listed status........) can that part alone be mecahnically protected, or does the whole thing need to be sorted ?

All fifteen odd circuits (five levels, outside, garage, kitchen...) will be on RCD or RCBO protection with two CUs to accommodate sensible combinations of lights/ rings/ trips/ inconvenience scenarios.

Thanks in advance for reading. Hope it makes sense.

PS. Badger: 1.5mm cable opinions. Sue them for defamation of character or slander; perhaps both and give the caretaker a slice when ya win !!. Bang out of order they were and thats _not_ compensation culture talking. People can't just say c**k faced things like that to your face with witnesses and expect to get away with it.

 
Welcome to the forum - looks like you have a good job on your hands there!

I take it you're not a spark? You know about notification?

:)

 
indeed I'm not, trying to plan where to run stuff. Got a good spark on hand to help etc, but he's away and I'm trying to learn a bit about whats going on to do donkey work and submission to BC.

sobs.

 
Few questions:

1. why do you want 2 CU's when 15 way (plus) available an if you are a very wealthy man you could have a RCBO on everything?

2. I'm confused by your opening statement - is the existing wiring listed or not? Are you doing a full re-wire? (assuming so)

You can buy new toggle switches if you want to keep the look

:D

 
No sorry, a flippant comment about listed wiring :eek: should be in a museum though..

RCBOs on everything would be simpler I suppose, but as you say needs some coin to sort that (like another

 
as opposed to a rocker.... ? Sorry, couldn't resist it..

 
I like this man, he,s already half mad.

Quick point about the safe zones , they don't apply to surface wiring ,say, in your basket tray, even a plumber would'nt damage them like that.

The RCBO option is very expensive to my mind , go for double split boards.

I don't know if PVC insulation is affected by farting , can't find anyhing in the On Site Guide. Specs will know when he logs on, hes generally full of wind. ;)

I must have been to buy this place and will be totally when finished!!

ta for advice re safe zones. I can now think more clearly about getting stuff planned and leave slack for final positioning of CU(s) later after two or three very awkward beams are fixed (i.e. right over the incomer)

Its all rather a splendid nuisance I must say, what ?

By way of confesssionary I have, in the past drilled holes immediately above a light socket (yes it did; <flash>), repaired loose floorboards in a girlfriends top floor flat (uh huh, sure did <psssssssssssssss>) and repaired loose floorboards (after having the lot up hours earlier to replace the bog so I had SEEN the pipe in question, even albeit reluctantly had my face pressed against it at one stage) in now present wife's ex house (yep <psssssssssss>). Fixed that one by threading the hole with a 5mm tap and screwing in a 5mm SS 8mm long set screw with ptfe on it. Never got a drop out of it after that. I know, I'm bad...

_NEVER_ again will I commit such crimes and intend to do all that is possible to prevent others from doing so in this place.

 
yeah, want one. fed up with 20 and 25 mpg max from these two. Mind you, the merc is lovely, but hey, this is about eclectics isn't it ?

 
In a simple answer-though others have said things. if circuit is rcd protected safe zoners and conduit-protection-need not apply. Thats the first scenario-but as it is surface wiring also not needed safe zones or rcd protection as if its in plain sight its deemed a moron would cut drill through it.
