2. Modern terminals are p.p. and do not reliably grip the tails in my opinion. They are only a single screw device with shallow grip on the conductor. .
Good call that man!
It does worry me that conductive metal housings for consumer units has become the norm. Fully insulated consumer units have their merits in the domestic market from a purely electrical viewpoint in real world situations. I perceive it as less of a problem in the none domestic although I might be deluded.
Thankfully I rarely work on TT systems but like Zoom said a pre consumer unit RCD housed in plastic would be my choice (yes I know its unlikely to be 30mA or less therefore not counted as personal protection but hey ho makes it safer IMHO)
