Mcb could be isolated?
I had a customer once that was adamant that she didn't want the fan isolator......it was an inline fan situated in the loft so I ended up putting it on a 4pin klik rose.
I phoned manrose about this, they confirmed to me that you only need a fuse in the permanent live and not switched live as its the permanent live that will have the draw on it from the fan and the switched live is literally a trigger, so they said fit a 3 pole isolator with a single fuse in the permanent live only.
what do you make of this? I tend to agree with it, plus if you are doing maintenance on the fan you should use the 3 pole isolator so it kills all power.

Well hang your head in shame fella......such things are classed as LSC's and are not to be used for any other purpose,dont have the BYB to hand but 559.6.1.4 applies I believe.
Like this?This is a reply I gave on a previous thread :-
In reply to the op it is possible to achieve fan isolation of all lives, fusing of both lines and have the bathroom light unaffected by fan isolation using just a dp sfcu and a dp light switch. The wiring is a bit 'busy'.
Supply into dp switch, two x two core cables to sfcu and one x three core from sfcu to fan. Connect as follows :- Supply l to dp light sw S1, n to wago in light sw back box. Using one of the two cores cables, light sw S1 to sfcu l supply, sfcu l load back to light sw S2. Second two core, light sw L2 to wago in sfcu back box, n from light sw wago to sfcu supply n. 3 core is connected to sfcu l load, sfcu n load and switched line to sfcu wago. The light is connected to dp light sw L1 and n to light sw n wago.
Description looks confusing but draw it out.
