Yes, that the simple solution, ...The 40W LED TV will come with a lead with a BS 1363 plug containing the appropriate fuse. Plug it into a BS 1363 socket. Job done.
I basically agree. The fixed wiring will be more than adequately protected by a 6A OPD and the only downside would be the slight inconvenience of the MCB operating if someone decided to plug in a fan heater. I suspect that a lot of this is about psychology and "feelings in people's bones" - although we know that 13A through the circuit will not do any harm provided the MCB operates as intended (and probably no harm even if it doesn't!), that situation 'doesn't feel nice'!It's all the malarkey about having to put a 2A or 5A BS 546 socket in because it's a 6A lighting circuit which is misguided, complicating and unhelpful.
In any event, a 5A socket with an unfused plug could theoretically present a problem if, as I was suggesting, the TV (or whatever) came with a mains cable that could not be adequately protected by a 6A MCB.
So, all in all, I think we are agreed!
