Hi Guys
Is there a reason why installation ref method B (in conduit or trunking on a wall) not listed as an allowed installation method on the maximum cable length charts (table 7.1)?
Regards
Hi people i just sent the docs to DSB norway for electrican , but the reference from electric company that i used to work i now its have change to Gjedosis company wich not have to do anything with electrics installations does this will
cause anything problem now or in the feature ?
I could really use some guidance as I'm at my witts end...
I have a 2010 Ford Taurus SHO with a low 5V Reference Signal (P0642).
I first had this issue a couple months ago.
I ruled out the three sensors on this circuit as I still had <1V with all sensors unplugged.
I changed the computer but...
I am interested in opinions on the following. Looking at GN3, page 126 the example of a Generic Schedule of test results lists the reference method as 100. When I look at the OSG Table 7.1(ii) on page 74 it lists A, B, C, 100, 101, 102 & 103 as 'installation reference methods'. However when I...
Hi everyone.
What's the correct reference method for cables (2.5mm t&e 32A? ring main) clipped to wooden joists between the ground floor and first floor. Standard build plasterboard ceiling, chipboard first floor. The joists are to be filled with loft type glass mineral wool insulation. Joists...
T/E clipped direct to brick. however, kingspan backed board is to be fitted so insulation direct onto cable. my thoughts are 102 as cable is touching wall, but not the inner board as described in BS7671.
Got an install that doesn't quite fit any of the tabled methods... more than 3 SWA's laid in 6 x 6 galv conduit, inset in screed / concrete, with lid. Ref 70 applies to ground (soil) and 118/119/120 is direct to concrete which has different thermal propogation than the galv that they're...
evening all
I am wondering what the installation methods should be for cables run under floor boards and then into stud walls but without thermal insulation...102,103 dont seem relevant and so my understanding leads me to think it would be a cross between c for clipped direct under the boards...
Hi there, I'm needing some guidance in how to interpret this reference method.
How could one be sure that the installed cable behind the plasterboard ( in my case) is actually touching the inner wall ie the plasterboard?
I'm going to have a 25mm service void on my insulated stud wall, but I'm...
Evening all
Just wondering what would be the reference method given for a twin and earth cable in a cavity wall without insulation....I understand with insulation its either 102 or 103 but these massively de rate a cable and so was thinking is it b without the insulation as it acts similar to...
Good morning
I am just wondering what reference method is suitable for the old single core sheathed cables if they at some point enter an attic space under insulation.ive had a read through the regs book but still unsure
Cheers for any responses

Is there a document that dechypers what cable markings and codes actually mean? 6181Y and the like.
I've looked on BCA, Doncaster Cables and a few others but can't find a simple explainitory guide to them, closest I've come is the BS EN standardisation document when codes changed to tie in with...
I recently got pulled up over my reference method I put down on a fuse board change at an assessment.
I chose to use reference method C and he said he wasn't happy because there could be worse in the house. I had been in teh lost there was no insulation other than vermiculite and the cable was...
My ECT 5 volts reference is dropping to 2.3 volts when the sensors is plugged in. What could be causing the volt drop please? Also return voltage to the ECM is nothing at all
Thanks

PaigntonPete -says he has connectivity issues !
..i previously had similar issues with "Maplin web site and PC" ...
Sadly that test is no longer available.
Sites with a shopping basket are normally Good !
I wonder if anyone could assist with this query please ? I am a newbie, so any guidance or alternatives would be greatly appreciated.
I need to run a ring final partly against a wall with internal 25mm Celotex type insulation. The additional Celotex being needed due to reduced cavity...
Following on from another thread I have just replied to it got me thinking about ring circuits and reference methods.
Appendix 15 shows a ring on a 32A MCB. It does begin with a get out clause regarding thermal effects but it just points you Chapter 42 which deals with fire.
If for example we...
