CU at ceiling height is readily accessible with a walking stick. all a disabled person needs to be able to do is reset MCB/RCD. anything else, there's mastercard (sorry, masterspark)
and how many CUs are fitted with those cheapo, nasty blanks in the cover over unused ways? any 4 year old child can flick a blank out and stick his/her fingers in , onto a live busbar. so why fix a CU where a 4 year old can reach it? political ineptness gone mad. cater for the small minority to the detriment of the majority.
I can see little johnny having a great time playing with all the shiny switches while "being a big boy".
