However, Penelope, the potential for harm of break in a ring can be quite high - particularly if you have a lot of things powered off it - so, even if it is a good DIYer friend, get it looked at soonest and, if your friend cannot check the ring continuity, it really might be best to bite the...

Sorry, I didn't make the question clear. You say so how is the cable going to bridge the gap between the post and the caravan - is there a gap?

How does it get from the post to the van?

As a registered "One Man Band", I'd have to say yes. The self employed guys, having gone self employed after working for big firms (mostly) are just as capable and efficient as anyone a big firm is likely to send round - maybe even more so. Provided they are a member of one of the Competent...

It's a relief, isn't it! :lol: :lol:

How old is your house and the wiring? This, basically, means there is no RCD protecting you against electrocution by, for example, running over your lawnmower cable in the garden. Such an RCD has been a requirement since 1992 I think. Using an RCD socket or a plug in RCD adaptor for garden...

A .4s disconnection time is only req, IIRC, for socket outlets (413-02-09) and kit installed outside the earthed equipotential zone (471-08-03) - from the OSG, so I think I've got the actual reg numbers the right way round, I'll have a look in the 16th Ed later. This means, that a light, fixed...

Most lofts will allow you to get the cable out through the soffit area so that you don't relly need to make any holes in anything substantial.

One reading of this suggests they're not necessary at all in domestic premises where a 30 minute fire resistance is required. http://www.iee.org/Publish/WireRegs/WiringMatters/Documents/Issue14_2/2005_14_spring_wiring_matters_installing_recessed_luminaires_in_ceilings.pdf

I use good quality freezer bags, take the socket screws out and bag the socket and wires completely using cable ties to secure the bag around the wires (that's after it's all properly isolated!!). I find this is most likely to allow me to return after the plasterers or painters and reset...

I don't know this shower at all, to be honest, but any from a piece of kit drawing in excess of 40Amps - almost regardless of any other symptom - must, IMO, be investigated. Does sound, at first listen, a bit like a replacement is called for.

Where your rewire is part of a complete refurbishment, as opposed to an isolated project in a building, the full weight of Builduing Regs will apply where appropriate - that includes socket heights etc. Depending on what you've done so far it is possible you should have already involved the...

Find the Junction Box, is the best advice I can give. It must be there somewhere in the ceiling/underfloor void. Any alteration you make is best made from there.

Where you join cable, the joint needs to be over insulated, so with choc blocks you can use choc boxes - and with crimps you can use heat shrink - but these won't fit into the back box (unless you've got a 47mm box for some reason!). If the joint is via a screwed connection it must be...

From what you say, each of your 2 way dimmers has one live feed coming in, this is then linked across to the other way of the 2 way dimmer to provide the live feed for that light. The Blue and yellows from both the coms (~) is the live feed out to each light. Go to the light you wish to remove...

What I mean is I'd remove the vertical cable joining 2 adjacent sockets and replace this with a new connection between the two running horizontally and connect the extra sockets etc into this. If I only needed a couple of extra bits I'd run a couple of spurs from existing sockets to create the...

If you are installing just for the home cinema kit, would a 13Amp fused spur do? I don't like the idea of a choc block as I like to keep joins to a minimum so, if a spur wouldn't do it, I'd try to join into the ring main horizontally, between electrically adjacent sockets in the ring. In the...

Why do you want to extend the ring? What is it you want to do with these new sockets?

Extra Low Voltage lighting is considered a special installation so is notifiable. Adding lighting points (which mains downlighters would be) is not notifiable if; a. it is not a kitchen/bathroom/other special location b. the existing circuit protection is suitable for and provides...

First - the removed light. You can't just remove a light, join the cables and plaster over them. You have live wires running through your wall with no indication they're there - that's a recipe fpr someone, sometime, putting a nail through it and experiencing, first hand, the effect of...
