Advice please, I have been asked to fit a number of downlighters in a plastic cladded ceiling.Any advice/reference on particular make/model. Regards

Gas soldering iron looks favourite. I'll give the gas cooker a miss as the joint is in the loft and the hatch is a bit small!!!! Cheers

When heat shrinking joints what is the best size sleeving for 2.5mm crimped joints. And what is the preferred method for applying the heat. Regards

cheers bas The ring is calculated at 80m2 and as you suggested the ring runs up and down the walls, so with the addition of 7m2 it will be just inside the maximum floor area. Conduit and crimps? Struggling a bit on this one. Regards

Cheers M1, The problem I have is that the nearest socket on the ring is on an external wall in the middle of a decorated room which has a concrete floor and the CU is on the other side of the house. Would 25mm conduit using the the appropriate enclosures be adequate? The run outside is 7m...

Is it permissable to extend a ring main by taking the cables out through the back of a socket, into plastic conduit, along the outside wall and then back in to building further along the wall?

Cheers BS Can you recommend a particular make or model and how much am I expecting to pay? Regards

Has anyone got one of the above, if so are they worth investing in and how do they actually work? Regards

Chaps Why then, are there calculations/installation methods, for cables enclosed/touching insulation on one side in the holy Regs?? I agree with polystyrene insulation having adverse affects with pvc t&e but as said earlier if standard fibre glass is being used "the cables can rest on top of...

The easiest method is to run the cables inside the dwarf wall and rest it on top of the insulation, doing away with running it in conduit. Each back box can then be fed through the knock-out at the rear of each box to the next etc.. clearing insulation behind each socket. This method is well...

Ideas please, When doing an initial check for continuity at the ends of a ring it became apparent that there was a brake in the CPC loop. After checking all the sockets on the ring for loose connections no termination fault was found. A broken CPC somewhere in the cable seems favorable but...

If it cannot be unplugged due to being hard wired through a fuse spur on the circuit under test would switching off/removing the fuse be surfice or would the appliance have to be disconnected at the spur. Security lights, heaters etc. Thanks for clearing this point up.

Advice please When testing a rcd protected circuit where and how would the test be carried out? Should you unplug everything on the circuit under test or just switch it off at the socket. Cheers

Thanks for the speedy reply My problem is that the cables for the W/lights are usually put in as a 1st fix weeks before the 2nd fix is completed, so i have no idea to the design of the light fitting. So as you suggested back boxes should be used. Bog standard square 16/25mm deep galv? Cheers

Does anyone Know if a wall light which is fixed to a block/plastered wall needs a back box, or can the block/plaster be chopped out to a suitable depth and the connections be done in a standard term block. Nowt in OSG. Cheers

If your really keen I would suggest enrolling on two short term courses. C&G 2381 (16th edition) which will give you insight to the rules and regs, and concludes with a multiple choice exam. C&G 2391 (Electrical test and Inspection) which enables you to test your handiwork fully, this finishes...

As expected, Cheers Ps Do you know if the local supply authourity charges for up grading the service fuse as it is only a 60A. A bit low or is this standard for a TN-S. Regards

Advice Please About to install a radial circuit for an extension. The feed will come from a spare 30A plug in mcb from an old wylex cu and run in 4mm T&E. There is currently no RCD protection on any of the circuits and my concern is that this new circuit will probably feed appliances outside...
