6A lighting cct to supply a 13A socket

Farmboy
So, we all know about feeding lights from a socket cct, but would you do it the other way around, running on to a single 13A socket from a 6A lighting cct (which is wired in 1.5mm2, to run a few LED's) to supply a lawn mower and similar items? Somebody was given a quote to install the socket.

    Not in my view best practice, but acceptable in certain circumstances when it is known that the socket will only be used for a low loading appliance. Examples include a loft mounted TV signal amplifier, or a modern central heating boiler.


    Not suitable for a lawn mower IMHO as I perceive some risk of the 6 amp MCB tripping. Also a socket normally used for a lawnmower might well be used for other garden tools some of which have substantial loadings, or for an electric barbeque.

    You could ask why a circuit in 1.5sq.mm. has a 6A MCB.

    I've not as yet seen 1.0sq.mm for lighting in my area of Scotland - they like their 1.5 up here!

    Connecting a load greater than anticipated could well be expected - it's a socket to be installed in a bin shed for a block of flats - and the sparky who gave the quote to install it is going to take the supply from the lighting cct supplying the lights in the communal stairway ?.

    I presume what was being questioned is why they have opted for a 6A device over a 10A device.

    That's not really the point I was making. Why the 6A MCB?


    Could you have a 20A/1.5sq.mm. (method C)  lawn mower circuit with some lights on it?

    I wouldn't do it I don't think it would sit comfortably with me. On the other hand if you were to install say a 5 amp socket then yes that in my view would be OK

    Is it your opinion then that accounting for installation method, shock protection, thermal constraints and VD re the existing lighting cct, upping the cb to, for example, 16A (subject to the lighting manufacturers installation instructions) and putting a single 13A socket on the end is ok?

    Why would it not be?

    Well apart from having asked about upping the cb size, i was simply asking whether you would put a socket on the end of a lighting cct, to which you're apparently saying yes. So there appears to be divided opinion.
