Apparently the regs say that junction boxes with screw connectors should remain accessible for maintenance (ie not buried under floorboards or loft insulation) because over time the copper wires deform and the screws need to be tightened up. That seems to make sense to me because I've found several times a flickering light problem was traced back to a loose screw in a junction box. In the past I've muttered something on the lines of ..."bl**dy electrician never tightened it up properly". But maybe all is forgiven and they were tight at installation time but became loose over time?
So my question in view of this is ...How often should one go round and tighten them all up? And should we do the same to all sockets, spur boxes etc.?
And the next question is ...Do you think the vast armies of loft insulation installers that Mr Brown is encouraging, will think to reposition all those loft junction boxes to maintain accessibility? .
