Fused Spur and 1G 13A for double back-box?

[JohnGeddes]

I have a project where I need to take a (fused) mains supply for an HVAC control box (in a village hall) without disturbing decor. The obvious answer would be to replace a 2G 13A socket (double backbox) with a combined double unit (or modular units fitting into a double faceplate) that provided a Fused Spur in place of 1G, leaving the user with 1G 13A still available. But I can't find anyone offering Fused Spur+1G 13A in a combined double-faceplate unit, nor can I find any modular system that would allow this.

Ideas, please.

One way would be a short legnth of 100x50 dado trunking mounted over the existing socket....into this you could fit a twin socket and FCU in the clip in boxes,and end caps to finish.Be neat and tidy.

Or fit a dual box and have a single socket and FCU

I agree with this. Its a no brainer. Have a look at these dual back box - Google Search
Then as stated just buy your single socket and fcu fit and away you go.

Just remember that the dual boxes are a bit wider than the existing double gang so you'll need to do a bit of wall bashing too.

Thanks for the suggestions, and so quickly!

The dual back-box would clearly allow mixing of any two single units - but only at the cost of knocking out more wall for the wider back-box. What I was looking for was a solution that DIDN'T involve risking damage to decor.

The trunking solution is one I will look at - but it is sad to have to contemplate surface-mounting when I have a recessed back-box that is theoretically big enough to accommodate both a fused spur and a 1G 13A if only somebody made a front-plate unit/module system in the right configuration.

If your careful you should be able to chop out the small bit needed without making any visible damage. The backbox that's there at the moment is not actually big enough to accommodate the two points.

Can you not just have the HVAC unit on a plug and plug it into one of the existing sockets, the plug will provide the fuse and if it is a switched socket the switch.

AC Guys dont like Plugs Richard as they can be pulled out and not plugged back in

Dual box would be way to go if your good you shouldnt damage decoration while digging out even if you do it will only be small bit

It's not so much cutting out a small bit for a dual back box that will result in damage,it's getting the existing double box out....if there are flush cables into a KO the box has to be tilted to come out....which means a bigger hole.

This is a much worse solution, but you could set the HVAC control up as a spur from the double socket with an inline fuseholder either in the socket or the control box, I am not sure this would meet requirements for accessibility or identification but would fuse the supply.
This is not a good idea.
