All many thanks for advice. On reflection, and given that this house has NO rcd protection of any kind, I have decided best course of action is to install two new rcbo cu, one on one phase for majority of services, and one on another phase for essential services. Genny will then supply second cu...

Or is that just the date of the BS?

Definitely MEM... definitely 1979!

Outdated by the look. It is a Memshield...no number...dated 1979! As it happens I have a spare board....but I suspect complete replacement is overdue. Is the PME installation an issue? It seems that neutral continuity is important??

I sort of knew this would get complex. First problem...there is only a single board...looks like a MEM industrial unit and you can select which phase you connect to by selecting specific RCB slots. It is also a PME installation...which as I understand it gives me concerns re neutral continuity...

Thanks b.a.s! I suspected I would have to isolate all incoming lines. Was trying to give myself a simple indicator when mains restored by leaving external outbuilding phase connected. Guess this would be unhealthy with a shared neutral though? I have considered auto change-over but cost is huge...

Looking for some advice as to the art of the possible prior to making a numpty of myself in front of my electrician. Current board is three phase which has been split so upstairs circuits on one, downstairs on another and outbuildings on the third ( house used to have all electric heating I...

A while since I have been on the FORUM. I have been advised by an architect to get some structural engineer calcs done, but the quote for two calculations is more than the architect charged me for the entire set of plans! Basically, I need a 2m access in what was an external wall, but is no...

Well I would replace them - one for one replacement for wired cartridge fuses still available. I would trust a circuit breaker before I trusted the speed at which the excess current melts the fuse wire - and more importantly the current it takes to melt it!

Hi Spark - Now in the process of taking all sockets off to see if I can find the other one that has the neutral disconnected - and in so doing have discovered a new spur, and a new socket which has been inserted into the ring - and a wall light that is fed from the mains ring, with no...

Hi - recently changed sockets in a room - and behind one, I discovered one of the neutrals had been disconnected and taped over. Sockets do not show any neutral faults, so the ring is complete one way - but when I connect the "taped over" neutral and remove the other, I get a neutral fault...

You think? Did you see the picture of the guy who had wired all the live services into the wrong side of the consumer box? So the circuit breakers were not actually in the circuit!! Assume nothing when dealing with DIY electrics!!

I have a couple of picture lights on two other walls - very slim line, and look great. The two other pictures are on a chimney breast, and running power cables to them will be difficult due to the design of the house. The pictures are acrylic, and provided the light source is low UV should be...

the pictures are originals - no glass. Which is why I don't want to use picture light, coz too close to the picture and heat/light might damage. But finding a light that can frame a picture from about 2m is impossible!

RF - great lights - but had not appreciated just how expensive!! I will need two - so may not be feasible for what I am looking for. Great light though!

do you know of a suitable light fitting for domestic use that can take a profile? I assume it will need a slot in front of the lamp?

Thanks Iggifier... I will take a look. Not sure if it will cast a square of light, but can always try!

Add Sarcasm ident? Not sure how I would do this. but for the avoidance of doubt - DO NOT hide live services which are not correctly terminated behind wallpaper...or anything else for that matter!!

a spotlight that can be adjusted to light a picture, ie throw a square light beam onto a wall? I have looked everywhere, and they are all bog-standard round spots. They can do this in the theatre - can I get a mini theatre style light to do the job? Any pointers welcome. Thanks.

I am amazed! No earth faults popping up around the place? How more people are not killed by these bodge job experts is a mystery to me.
