Consumer units and equipment outdoors

Alcomax: 
 

 

I thought the OP was generally about stuff being outside and subsequent IP ratings required or achievable,  not for when these accessories are installed in severe locations that actually do require IP66/IP67. 

 

Hang on … I made the point that a 5  mm drain hole can cause problems even where there are not “severe locations” … but also so can “tight sealing” to IP65/IP66 without ventilation … again no “severe location” … and mentioned the drain plug in the first place.

I think that GTB was only pointing out a few different options available where there are  additional constraints, in addition to another point, which I think the point you've perhaps missed completely: that the 5 mm drain hole is OK in many indoor locations with conduit (to stop condensation) … outdoors, if you have a conduit install, you need an appropriate drain plug (but you might need one anyway because of internal condensation due to pressure and temperature changes) !

Most of these sockets end up on outside walls of houses, so unless it is a jet washing area such as decking, any notional reduction in IP , in respect of moisture entering from outside, is minimal , reflected in the guidance given by the manufacturer. IP55 may well still be more than adequate for where and how the socket is. Do not be tied to maintaining the sockets rated IP in all circumstances, unless it is absolutely required.

Conduit coming from above, behind or sides will also bring condensation as above. It does depend on how exposed the side of the house is … I wouldn't generalise.
