double pole MCB?

[walsh builders]

Does anyone know of an 80a type b double pole MCB?

I can't find one anywhere.

Why do you think you need a double pole MCB?

 

[walsh builders]

It's for isolation of meter tails with fused protection. But limited space, so MCB would fit better

 

[Darkwood]

I would think you are unlikely to source one easily (lack of demand) as the permitted Zs values would be too low and unlikely that you could satisfy them unless you sat it on the incomming cutout feeding an adjacent load or oversized the cables plus extra earthing on a run of any distance, if you get the picture :wink5:

You get a 2-pole 100a isolator which is the same form factor as a 2-pole MCB. Look at the Hager SB299 for example.

Think he needs a switch fuse!

I thought he meant the tails were already fuse protected but I've no experience with UK installations so probably a stupid assumption .

You would still need an enclosure.

How limited is your space ? Would a KMF unit not fit ?

 

[walsh builders]

Yes, but a smaller enclosure

precisely but I suspect the next question will be how can he connect SWA to it!

 

[walsh builders]

Not connecting swa. As I posted its to protect meter tails.

That click one looks smaller, I may be able to fit that in, thanks.

Do they not need RCD protection if not SWA?

You should be able to get one of the shelf most places in town. Wylex and MEM/eaton also make the same thing under their branding.
