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.</div><div><br></div><div>Many of us work with battery systems, and not everyone is a certified electrician. I'd love to know some ground rules.</div><div><br></div><div>thanks!</div><div><br></div><div>Hugh</div><br><br><div apple-content-edited="true">
