Not entirely related,
but there is a company here at the moment looking for Tenders to fit remote metering units on some household meters.
My understanding of the local (if not national)laws here, require a person with at least Electrical Inspector qualifications, to do this work.
I know that locally, you need permission from the local Lines Company to break meter seals.
Doing so without permission will land you in really hot water (and I'm not talking about the Night Rate either). [Linked Image]
Maybe things are a little more lax overseas with regards to metering equipment, here, unless you have permission, meters are out of bounds to most Electricians.
