Are 'smart' meters actually being deployed to 'commercial users'?1974 and the 3 day week. .... It worked with only a few companies / large users refusing to limit themselves to just 3 days a week. It could not be enforced where the local network could not separate supplies to commercial users from supplies to residential users. ... Smart meters provide the facility to selectively switch off supplies, If the meter's function is purely to record the amount of power used and the time it was used ( variable time of day charging rates ) then there is no need for the 100 Amp relay that many smart meters have inside them.
As far as domestic installations are concerned, as I understand it suppliers appear to have 'promised' not to use the 'remote cut- off' facility, even though it exits, I suspect at the behest of their lawyers. Even in this forum, we see enough fuss being made out of the theoretical risk (potentially 'to life and limb') of being 'plunged into darkness' because the installation does not have enough RCDs - so if the same were to happen as a result of deliberate ('remote') human action, it could perhaps be argued that there was 'culpability', all the way up to potential manslaughter charges?
