[RE-wrenches] "Extra Low Voltage"

[Hugh Piggott]

Me again,

Maybe that was confusing.  Just to clarify this question, I will break it down as follows:
What qualifications do you need to legally work on electrical systems in your country/state?
Is the circuit voltage a factor, and if there is a different rule for ELV systems, then how is ELV defined?
What other factors are applicable such as status (homeowner, installer, paid/unpaid) and location (inside home, wet location, etc)?
Thanks for any observations.

Hugh

I'd be interested to learn what rules people follow regarding such work and who can do it, for themselves or for money, in what environment (inside or outside the home for example, dry or wet etc) and at what voltages?  The definition of ELV seems to change depending on various factors, one of which is whether it is "separated" (floating and well insulated) or not.
