I have just moved into a house and in the living room is an old gas fire. Its freezing due to the air coming in through the flue and the fire is half off the wall, no way I would turn it on. I just want to move it, the gas pipe comes from the floor. The top has a flat head screw and a...

I ask as we have a pillar supporting 2 major structural steels whcih according to the drawings should be 20N brick. However it is a mix of semi-engineering and facing brick. Would this likely to be adequate?

Thanks Guys John, have done as you said and located the prblem in minutes, builder has nicked one of the cables clean through the sheath and nicked the phase. Glad to have found it before it was plastered in.

How do you half the ring?

No nothing. Tested prior to plastering to make sure everything OK, all connections made with connector blocks to complete the ring.

These are the results for the test on our main ground floor ring, the phase/cpc resitance test seems a bit odd what may be going on? Continuity Phase/Neutral 1.99 ohms Continuity Phase/cpc 2.98 ohms Continuity Phase/Neutral at each socket .46ohms all within .05 other than spurs at .59...

What should be the minimum thickness of Oak door linings when hanging heavy oak doors? The local supplier can supply 22mm but we have been advised that 28mm should be the minimum together with double plugging. Can you help

I have seen a number of computer generated circuit diagrams, normally lighting. What is the standard software for producing these? Many thanks

Where live to neutral? I am asking as we have LABC coming to test the electrics and their electrician seems a bit clueless and we dont want all the transformers blown, there being one on each light and the junction boxes being inaccessible save for the last one on each circuit.

Too much Star Trek :shock: If my lights were on my space ship (already tested) commets would be OK!!!! :wink: As not advice would be great before something blows (other than the clingons :twisted: )

How do you do this on lighting circuits with lv donlight transformers attached to the circuit? The junction boxes could only be accessed by removing ceilings in some places!! TIA

Any more help?

Each Light circuit will have between 4 and 6 50 watt LV lights Sorry Rings was Misleading now I add them up but its as follows. Cinema and Cinema Equipment are separated due to the equipment. Upstaris and Bed 1 split due to floor area/length of cable. Rings/Radials are: Kitchen Main...

We have been advised that we need to upgrade our domestic supply to 3 Phase by the Electrician. We will have 8 Ring Mains, Immersion, Cooker and 2 Lutron homeworks Panels (with 52 light circuits) Apparently we would need to feed one of each Phase to 1. A standard single Phase CU for the...

I know there are lighting requirements for commercial building, i.e. minimum lumen output, etc, but are there any regulations for domestic for a minimum brightness or can you be as creative as you like in designing schemes.

Do the building regs apply to touchpanles that perform many function. A colour screen that displays information is basically unviewable at 1200mm. As it displays information it needs to be approc 1600 to 1800mm. Does anyone have any experience of using these? Edited to add...on further...

Thanks for the reply. Building control Surveyor confimed that the 450 was from the finished slab.

I know the recocommended heights (450mm/1200mm) but what is the refence for the finished floor height, the concrete slab or the actual floor covering. I ask as we haven't decided what to have, i.e. carpet which would be about 5mm or wood/tile which can be up to 35mm. Thanks
