New Mexico used to have a low voltage electrician. It was for
communications guys, and was limited to under 50 v.
Actually pretty useless, since most systems had inverters. Also it
wasn't that much harder to just get a regular electrical license.
Also, some considered even 24 v systems to be over 50 v, since the Voc
in cold weather could exceed 50v.
Generally, for maintenance/ battery replacement on off grid stuff, no
one worries about it. If you are doing new construction, pulling
permits, then you need to have much more than just the license.
Insurance, bonding, worker's comp, etc. are also all required.

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.

hi All,
I am trying to find some general statements that can be made about
the global legal position on who may or may not work on/install
"extra low voltage" (ELV) systems or equipment such as batteries, PV,
turbines etc.
I understand that in the USA this is a matter for state legislation
rather than federal. 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.
Many of us work with battery systems, and not everyone is a certified
electrician. I'd love to know some ground rules.
thanks!
Hugh
