wiring downstairs light circuits

[driverman]

As some of you know, I'm doing a first fix for family member. I now know that in a modern house its best to do loop method of wiring from switch to switch due to modern day down lighters and light fittings only accepting one cable. I did have a thought though (bear with me) as there are 3 x cupboards on the ground floor of using flush joint boxes in each one to wire the various light switches to etc. I would still loop each LED down lighter together though. so all j/boxes would be accessible for test inspection and maintenance. Anyone done similar? thanks

Scolmore even have provision for 'loop'

Well said eye

That is one that doesn't make sense to me. You would have thought it more likely for a fixed JB to need strain relief if cables pulled?

Eh? If the junction box is loose and floating then it can move about, thus loosening cables. Think about it!! Daz

Just my opinion as to a flaw in regs in that unless a fixed JB has cables clipped (easily pulled out) to entry points, the strain relief is more important. Also, it's always fixed JB's that get damaged/lids broke off.

It's not a flaw in the regs though - they say that fixed wiring should be just that - fixed! Daz

I see your point Daz, movement, metal fatigue, movement loosening connections etc., it's just my view and as said in another post, D/L connectors are provided. Some have no strain relief but are far more likely to suffer 'movement'

Who hasn't floated a few. lol

They're much more 'easily accessible' too!!

Agreed that it takes time to move a mountain (so to speak) but I think you'd find the front counters of a wholesalers an eye opener!

You may well be right, and as i say (contrary to what others may think), i have no problem having a neutral conductor at a switch position when it's required. What i don't like and would never contemplate using myself, is looping through the switches, especially within domestic installations!!

Generally speaking, the times that I'll loop at switch in domestic is if the place is littered with wall lights, small fittings etc where you just know that you'll struggle to find space to lose the loop and S/L and really just need one cable at the point. Rather than litter the joists with joints, plan ahead and fit deeper boxes at the switches and sensible cable drops. But then I also only tend to use 1mm TE for standard domestic lx ccts so you've that little bit more flexibility again to be neat and tidy. It does use more cable that way, though.
