Small metal Sw/Fuse needed

Can anyone point me in the direction of a metal Sw/Fuse that is smaller than 230mm high please? (the smaller the better).

I intend to use SWA to CU about 6M from meter position.

Thanks but I'm looking for a metal version that I can terminate SWA into.

could you not mount it at 90 degrees? 

Unorthodox maybe , but sometimes you need to think outside of the box

I think you'd not find any smaller than this at 250mm high, and even if you did, you might struggle with the armoured in it!

You could go with binkys suggesting and make off into an glav adapt box tight upto it with a slot and grommet strip

other option is a mini cu, main switch and MCB

Thats how I did the alteration at my own house .   Theres a 60A  HRC fuse & a 100A DP switch  in the enclosure  but they still insist upon the usual isolator .

I did consider this but this is domestic job so dont think it will satisfy amendment 3.

Well like everything its open to interpretation but it could be said that a switch fuse falls within "consumer units and similar switchgear assemblies" and as such needs to be in an enclosure which is non-combustible (421.1.201)

Ah!

i thought you were referring to the metal 1 way unit and MCb and NOT the Plastic one, sorry

in my defence I was left unsupervised and alone with a bottle,of Mandarin and Chilli gin

I have found that Scolmore do a metal enclosure to contain their insulated switch fuse, whether SWA could be terminated into one i do not know .......

My take on this is the gear fitted in a meter box  OUTSIDE of the premises would continue to be plastic  , as with the equipment fitted by the DNO  & metering companies .

Plastic  cut-out ,  plastic 100A   main switches,  plastic  meters .    The only reason I fitted a metal sw/fuse was to make off the SWA  .  Had it been meter tails I'd have used the Scholmore   Main switch  shown above.

There is also an argument that suggests "Consumer Units and similar switchgear assemblies" are items to which 'final circuits' are connected in domestic premises. If some switch gear is only supplying a distribution circuit then it can be argued it is a distribution board not a consumer unit.  It pivots around the definitions where Consumer Units and Distribution boards are both described in Part-2. And a Consumer unit is a "particular type of distribution board" Yet regulation 421.1.201 does not refer to Distribution boards, although it does mention household domestic premises.  Why not just say all domestic distribution boards should be non-combustible if it applies to every thing?
