138/240Y System

[Cookie]

How would everyone feel about a 240Y system in a building with everything connected Line-Line?

I personally like (want) this system. No TN-C, TN-C-S vs TN-S debate. No earthing/bonding debates of how to keep the neutrals separate in a multi source or generator system. No fire or shock risk from a broken PEN/MEN. No need to keep track of live and neutral in a circuit.

Just asking curious.

You guys have a BS7671 code section?

Against copywrite to publish them online, however if your interested you can purchase them.

Because lightswitches are the means of isolation for each light fitting therefore need to isolate all conductors.

A light switch generally does not provide isolation it is a functional device to control a light.

I have copy of BS7671, just need the number which points me to the code section requiring double pole switching.

Exactly my thoughts and how the NEC views it. Control vs a disconnecting means are two different things.

As is I doubt there is much concern with a GU24 socket.
