Consumer units and equipment outdoors

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.

  • I had a further think about this … and I guess where we are sort of on the South side of the Bay, means we are often at the cusp of three weather fronts. Has the advantage of warmer temperatures than other parts of the West Coast, but of course, you get nothing for free !

    A couple of other effects of living so near the coast are sea breezes where you get localised humid air encroaching on the land due to pressure differences between the land and sea air masses, which can be against the prevailing wind direction. Also, in the evenings the air temperature can drop below the dew point and water condenses out onto surfaces. Camping by the coast recently, we often saw this effect causing everything in the tent to get damp so we zip up the tent which seems to help a bit.

    edit; just thought of a third, where you have hills or mountains and air rises over them causing a drop in temperature which could fall below the dew point and form orographic clouds. if the wind is from the sea and it is nearby, this effect would be very common. On the other side of the hills you get drier air, less water as it has already condensed out, giving the Foehn effect.
