On a standard hall & landing 2 way circuit (i.e both switched from either location), does everyone prefer using the 3 core method, with each light being fed by the appropriate circuit (i.e upstairs / downstairs) - are any other methods in current use?
Following on from the thread on Two way and intermediate switching (and related conversations) I was wondering where the "recognition" of just one of the methods comes from how far it had spread.
I've assumed preference stems from osg 7.4.4 as followed by Figure 7.3.
No reference is...
Completing my EIC's for assessment tomorrow with the NICEIC ... I'm used to using Elecsa certs and haven't come across 'Reference Method' before.
Changed CU, tested all circuits. Most of the cables are run either through the plasterboard walls (not in conduit, no thermal insulation), or...
Currently doing a rewire on an old house. Loft has 50mm joists at right angles to a large central joist 200mm. So I can clip cables along the centre of the loft with no problem. Using installation method 101 it would seem that I can lay the cables out to light fittings between the joists on...

Hi, looking for a bit of advice with regards to calculating costs and timescales for installing large runs - 300 mtr+ of multi-core cabling. To get an idea, the weight of the cable drum would be in the region of 450kgs.
The cable will be run over cable tray.
What I am asking is to get an idea...

Hi does anyone know the third method of carring out a continuity test method 1 is using the link to L-cpc in the c/u and measuring the open resistance the other end.
Method 2 is the long wandering lead
Method 3 is it some sort of live test like a loop impedance test? How do you do it?
