Or if it looks OK leave the rose where it is and run the tail from it into one light, and then on ito the second. This solves the problem of what to do with the extra wires in the rose, and reduces the risk of error. Otherwise duplicate the rose wiring carefully in a joint box or chocbloc plus...

The longer answer is, you are sort of right, it is not inherently safe, if the rest of the ring was unloaded, and you plugged enough stuff into the one socket, it would indeed overload the cable but not blow the trip or fuse. This is equally true of any spur from the mid point of a ring too, but...

probably better to confirm that first. A rod will have 20-100 ohms of reistanec to true ground, If as andrew suggests you have TNS this will have a company earth of a fraction of an ohm. Addin perhaps 50 ohms in paralell with this will do very little. More to the point, if youare worried about...

Unless the tank is pretty much perfectly lagged = does it feel cold to the touch? then there will be losses, and rather than heat up against the losses with the heater cycling on and off whiel you are not using it, it is better off.. If you live a regular routine then it might well be best to...

Assuming SWA Use house earth to protect the cable armour, but at destination, fit RCD as first pbject in L and N, and downstream of RCD use an earth rderived gfrom a local rod, and not connected to the cable armour. In the shed sleeve over the cable armour, if exposed, as it should be...

thats a 6 way box ban...

Oh I dont know - I did for a number of years... I used to go home for a few hours most days, just to keep my hand in like, but certainly most of my life was in the lab..

It could be OK, you need to consider if it could be damaged, how it mounts to the building and make sure all joins are weather proof.

They are a better solution, if it is big enough for what you need inside. I'd drill the metal box to mount the choc block too, but I'm like that.

Be aware that the 3.50 plastic box you linked to i.e. http://www.screwfix.com/app/sfd/cat/pro.jsp?id=11549&ts=89755, has no terminals inside - usually get filled with crimps or choc bloc singles dangling in the breeze. If done nicely then a big piece of choc block can be used but attaching it...

Assuming that is based on one of Anne H 's letters they will already have received its contents at least once. But of course there is no harm in printing a copy off in an extra large font and waving it flag-like under the nose of anyone who tries to overcharge though. That and the DSA...

Actually, as you are at the end of the chain, you don't need to. Connect the 2 reds to each other and nothing else. Connect the new fitting between the two blacks (one as live from switch one as neutral, but for that fitting it will not care if they are reversed so pick either way round). If...

If the cable is adequately protected against mechanical damage, sunlight and solar heating, yes. However, view it as much preferable to route indoors if you can.

Well now some loading calculations will need to be performed by a mechanical and structural engineer approved of by the building control office to decide if the removed material is significant or not, and if it is, then bracing timbers of the same or greater strength will need laying alongside...

Hmm. OK, either a tranformer with three independant outputs, one per bulb or a transformer with 1output split between 3 bulbs, either is actually fine. (an output is a pair of terminals of course.) The transformer should be able to cool itself, and dry, so not in the steam of the shower, nor...

No, but there are rules on where you can run in along a wall, if its route is not visible - see the permitted zones stuff in the refeernce section. also conside the risk of mechanical damage from boots/bycycles etc - is trunking in order?

Actually -that photo is someone who really made life much harder for himself than he really needed to. If the plastic box has a block of earth terminals built in, then as was suggested, a nut, a bolt and flying lead between it and the earth block is all that is required. If an earth block is...

Well its as easy for the oven maker to bring some rings to one live lug, and some to another, or have 1 big lug, and the electricity suppliers prefer a balanced load, and thinner wire can be used on each phase, so if the house has a 3 phase supply, it is sensible to share the load about. In...

Or it is pre 1970 PVC, and you are looking at the 'green gunge of death' as the PVC decomposes. Some cable makers had problems with their choice of plasticiser (some phthalate derivitives), and it leaches over time, and reacts badly with the copper. The decay is excaerbated by heat. Very mild...

standard back box, just overhangs a bit at the edge.
