The IET is carrying out some important updates between 17-30 April and all of our websites will be view only. For more information, read this Announcement
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.
Its very clear units are IP66 rated so completely dust tight and protection against jets of water, so please explain how you drilling “ one or two holes” in the bottom of the back box would keep that manufacturers rating?
GTB
Interestingly, IP66 is not guaranteed to provide protection against jets … well, it does the jet itself, but not always the side-effects on equipment inside the enclosure.
Please indulge me a moment.
Under certain conditions (such as jet washing, or where equipment is installed within 150-250 mm of the ground in a direct ground-mounted enclosure) where there is a sudden change in pressure or temperature outside the enclosure, condensation can form quickly inside the enclosure, or permit vapour ingress through seals. The only solutions are anti-condensation heating and muti-baffled “snail” vents with appropriate filtering or mesh (the best that achieves of course is IP65 with appropriate filters).
So, if equipment is installed in places that may be subject to jet washing, or within 150 mm of the ground, worth considering.
