I only know the Gent in a hopefully friendly sort of way and we've never tipped a pint together. We discuss his house building and I ask a lot of questions. When we talked about his electrics and he quoted me this British reg about lights and switches, who am I to argue? I just responded in the US of A our code would never allow this.

If you take the time to do the job right the first time you won't need to "find" the time to go back a second time

^ you have to understand the Brits are still trying to grasp this whole electrical concept.. That's also why 2 of their electric F1 concept cars have electrocuted a couple of their mechanics, hence they've had to shelve the idea for now until they fully grasp the concept..

Though there have been a couple of Brits that have answered on here that seem to have some basic concept though, based on their answers..

I don't believe it is EVER acceptable to break only the neutral.

A neutral switch when ON will have neutral voltage (OV) both sides, BUT when OFF the live voltage will zip through the light bulb and make one switch terminal hot. So, switching the neutral does not make anything safer, wet or dry

It is possible that the OP's friend is referring to the standard UK light wiring technique of running L & N to the ceiling rose and running a dropper down to the switch, rather than supplying power to the switch and having an 'upper' to the rose (as seems to be the Thai way).

I don't understand how that makes any difference.
Is the dropper on the live side or the neutral side ?

More Volts Igor

The dropper is always on the live side.

To be honest, it was a thought, maybe not a good thought. I don't have a copy of IEE 17th Edition, but I'm not aware of any changes permitting neutral switching so there has to be confusion somewhere in the mind of the OP (friend).

If anyone can come up with a sitation where switched neutral would be advantageous / safer, I'm all ears

Thanks for your input and I have not had any good opportunity to re-visit the question with my Brit friend

The Dude and driving force have it correct.
I am a pro..20 years liscensed electrician in usa and have done many projects in LOS, Viet, and Costa Rica.
It's very dangerous and life threatening situation. Don't trust Thai electricians.most know nothing about this..as for internet expat experts.....??
