how is that any different to what we had talked earlier (the reference
was about LV, not ELV)

You'll note that under those regulations, it means no one then is
allowed to work on the telephone system without a license, as standard
phone line can be up to 90V AC (when it rings)

AS standard states that ELV service must be separated from LV (low
voltage) hazardous service by a minimum of 50mm and 150mm at the
termination point

Go for fiber ... So much easier to work with... No need to care at all
about how you place it, smaller, lighter, more flexible and much much
greater bandwidth..
Price keeps going down too
