Consumer units and equipment outdoors

vantech

Hi,

Anything inherently wrong with installing consumer units outside? 

IP rated (IP65/66).

The plan is to install henley blocks into the exterior meter cupboard, and a supply taken to an IP rated lockable enclosure on the wall directly below the cupboard to supply an outbuilding.  

How does the sway in temperature impact MCB and RCD functionality? They all seem to be rated to sub zero temperatures and in excess of 40 degrees. 

Anyone with any extensive experience doing this? 
 

Thanks.

    ..Open the CU for servicing only in guaranteed good weather. Not something i would encourage. ..

    Have to agree with this. Having to reset RCD or OCPD in the rain/wind/snow/dark is not a good idea. As is having the “close” protection remote from the outbuilding. 

    A few questions;

    How many final circuits are envisaged? What would be their route, distance to outbuilding and installation method? Would the DNO allow henley blocks in “their” cabinet? What sort of outbuilding? Any services there that might need bonding? 

    Assuming the existing CU for the property is within 3m, why not take henley blocks from that location?

    Just trying to get a fuller picture of the installation
