As a boy I unscrewed sockets and light switches because human children are inquisitive. Nowadays I'd be protected by an RCD in the Consumer Unit But not if I open up the consumer unit!
The new requirement is that consumer units must be positioned so that the s witches are mounted between 1350mm to 1450mm above floor level. Many people have said how stringent this requirement is - there is not much room for m anoeuvre!
The consumer unit has often been positioned at a high level, in kitchen cup boards or above doors and coat pegs. The new requirement effectively outlaw s all these positions. It will be a design challenge to find a suitable pos ition for the unit.
