I think it one of those terms you pick up and use from the people you work with or maybe it crept in with the rise of the red plastic stuff, I never saw any "sand "come out when I sawed (grindered) them off, it was more like fridge grade copper really soft

On that last note how many sockets constitute a ring final ? I recently installed a new circuit in a hotel kitchen and it only had two outlets and as it had to be in conduit I did it in 2.5 singles, but the term "ring" gives rise to the idea that it must go around "somewhere" and back to the CU...

These were temp about 4 years ago guy never got round to it I have no idea why the conductors are in metal FP but the whole lots coming out soon

For a moment just a moment I thought well I never :!: :!: :?: then the penny dropped But BAS is right and so are the others who echo the veiws expressed they should stick to selling plants and paint at least no one ever killed them selfs with a pot of matt finish or a begonia, I haven't see...

I think most of us who are electricians have had shocks and most of the time it's a case of really should know better, my last one was when I was changing two external emergency lights I isolated the circuit and my mate told me when the charging light went out unfortunatly they were on different...

Yes I agree entirely I sometimes forget that this is in essence a diyers forum and get side tracked on issues assuming a certain level of experience, and I echo the comments on a main switch being provided by the DNO but without saying to much it can be done by them if you know who to ask, DM

I stripped back the perished rubber and slid on sleeve as far as I could i managed an IR on it and it was well within spec at 875.2 Mohms as it only runs two strip florrys after the break I will be rewiring the complete circuit I didn't want to make a mess of the place as it's laid out for...

Because it would have meant ripping out the steel conduit all the way to the ceiling the blank covers the original switch aperture and the new switch sits in a box below I extended the cable to reach DM

this is how I resolved it I have plastered the bottom since

thanks, I agree the risk assement part is a deciding factor here if it looks like a problem then it probably is DM

the metal backbox appears to be open ended at the bottom I think to accomodate a second switch it also seems to be screwed onto conduit at the top it's all rather chunky looks like cast iron and 50's makes sense as it,s not in the original part of the hotel but from the ammount of sooty stuff...

Quite apart from wether or not it is allowed and all the scary vids on the subject surely if there is no load then pulling a 100amp service fuse is safe, I had a discussion with a guy from a supply company who told me that their guys are issued with face shields, gloves insulated tongs etc for...

:P :P :mrgreen:

That is true as last year he bought a additional van and the IR was terrible changed all the sockets and light switches and it improved hugely but on the vans that are failing they were changed also but I take your point I may have to cut back to clean copper cheers DM

Any one know where I could dig up information on the hygroscopic nature of pvc cable I have a client who owns several statics,last year I did a full inspection on them but this year some of them have very poor IR on the ring and lighting circuits these are unheated most of the year and the...

My personall choice for my own use is a radial in 4mm mainley because if its a garage/workshop/hobby it saves going up and over any doors and easier to add to later for that piller drill / tig welder/compressor/ you promised youself DM
