Grapevine is full of rumours that the next amendment will preclude the use of conventional 70' rated PVC cables, inc twin and earth and that only Low Smoke LSOH cables will be permitted.
The ring final will be banned too. Must be, I`ve been hearing that for years now
I doubt that we will see an outright ban just yet, but perhaps some means of complicating ring final circuits could be devised. ?
Such as protecting each leg of the ring seperatly, and at some non standard current. Special dual MCBs that protect each end of the ring at 18.4 amps?
Followed by a requirement to also protect the neutrals, so we now need a special 4 pole RCBO that protects each live AND each neutral at 17.9 amps. (18.4 amps now being very last year)
So not an actual ban, but enough cost and complication to deter use.
