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.

    Within a few miles of the coast, consider protection against corrosion if outdoors. Many basic steel or cast alloy consumer units would be subject to being compromised after a very short time (2-3 years in some cases). The nearer the sea, the worse the salt concentration gets, although its effects can (dependent on terrain) be seen over 10 miles inland.

    In sectional concrete garages and some sheds, it can also be a problem too as they are not fully weather sealed - so for example, if you are within a mile of the coast, you might experience problems with metalclad accessories and standard-duty galvanized containment in a sectional concrete garage, depending on how exposed and subject to wind the outbuilding is.
