Most electrocutions occur when a DIYer switches off the switch and removes his ceiling rose believing it is dead "but I switched it off!" he says. Zap.


Electrocution Is he dead or what ?
If he is dead,then he is very unlikely to have a viewpoint

Even less a veiwpoint that we can hear

why not just turn the mcb of at the CU/DB, that way even if it is wired into the rose u wont get a zap

Well thats what SHOULD be done isn`t it....safe isolation?.....in an ideal world that is but many DIYers are simply ignorant of this............

You know what I mean :shocked3:.

suppose they dont know this. was just double checking what I would do. was thinkign I hope i dont do that, but looks like I know what to do.

If you wire to switch then more DIYers will have a go at changing the lights themselves. Keep it 3 plate so they get the sparks in

I reckon that most DIYers get confused because the installation instructions included with most fittings seem to only show brown and blue cables!!

I had a call out recently, because the homeowner had got confused when trying to fit a new pendent. 1970's house, black and red , but red and red on the switch cable, he simply didn't know what to do with so many reds!

3 plating the downlighters everyone wants is a PITA. There was a heated thread on here a while back about neutrals at switches that the IET has now given the definitive answer to. As have hager with their new loop on switch terminals. What possible difference is there between neutrals in a terminal in a ceiling rose and neutrals in a terminal behind a switch. I mean what difference is there REALLY, other than blind ignorance, preference and age old habit? I thought we were able to be free thinking educated designers able to apply logic and reason. Why apply this only to fault finding and not design.

I was just wondering more on the lines of the amout of cable used in either system and which was the most economical method in time and costs.

Thanks all for your comments.

it varies in terms of how much cable using either method
for lots of views on this subject do a search i am sure it will amuse you for an hour or so reading the replies

Your flat twin n earth is used more in a 3 plate setup nowadays (but can be used either way of course) wheras singles tend to go straight to the switch....and then through to the point/fitting etc.........so i guess it depends on your choice of cable and the scenario its to be installed in as well as cost.........

Maybe because one actually requires a neutral connection, while the other one doesn't!! Except maybe in the case of supplying an outside light, or a connection to supply a fire alarm/security panel.

Nothing to do with blind ignorance, an or old habits, but everything to do with logic and reason, with a good smattering of commonsense too...

It`s a bit like rings V radials...depends on the situation....you have a choice and both have their benefits ....and downsides so you make an informed choice as to ease of install, minimum disruption to either householder or production, cost of course and durability including the ability to do the job in the first place...........

I'd be interested to see how you make your lights work without a neutral! When you feed a switch in twin and earth the neutral is needed there to supply the light. You use the Switch as a JB, same thing as a ceiling rose.

Well mate if you were sad about the Reg advising that a box or enclosure now does not have to be fixed to the fabric of the building, you will be raging that the regs now want you to consider the provision of a neutral conductor at each switch position to facilitate the installation of electronic devices in lighting circuits.

So though it mentions electronic devices you may find that the wiring loop at the fittings could be a thing of the past
