Local Isolation - Electric Windows

Brendan Ashford

Hi all,

Advise please…..

Customer lIves in a bungalow and is removing the ceiling in her kitchen to make a double height vaulted ceiling. 

She is having electric velux windows installed, normally I would install a switched fused spur adjacent to the velux, 

Can I put the fused spur it in the loft space where we have a nice new wall with all the Boiler, PV system, TV amp etc mouthed, would locating it there be deemed local isolation for the electric windows?

If I did mount it adjacent to the velux’s it would be 3.3m off the ground. Hardly easy to isolate and probably contravening CDM regs.

And the customer doesn’t want sockets on show around the kitchen so is having things like boiling hot water tap, intergrated microwave etc, and wants only three sockets hidden under the pelmet of her cupboards. 

thanks

    I usually just fit a box with a blank plate next to the velux and put the spur somewhere convenient.  Usually next to a socket somewhere with a label on it.

    Generally if an isolation device is remote from the equipment it's meant to isolate then it needs to be able to be locked off - not all designs of FCU  have that facility. Also for TT systems the N needs to be isolated as well as L - which probably can't be achieved by locking out the fuse carrier.

    And if there is smoke coming out of the equipment the isolation device needs to be easily located and must be obvious in use. (Clearly labelled).

    And we need to consider switching off for mechanical maintenance as well 464.1.

    Do the Manufacturers Instructions say that local isolation is required? If not I suggest you do not fit it, this is gilding a lily that useless. If someone wants to work on the electrics, we have perfectly good rules for isolation. The "its on fire" situation is not going to change by isolating it locally and no one is going to find a ladder! This is the place for the main switch being accessible and known.

    The last two I did are supplied from SFCUs at knee height behind the full length curtains by the patio door with easily accessible and appropriately sized fuses.
