Compiled by ESV’s Electricity Technical
Advisor, John Stolk
EnergySafe continues its regular series
featuring some of the questions that
ESV receives on a range of electricity
installation issues, some of them relating
to gas installations. Also provided are
the answers together with references
to the Acts, Standards, Regulations and
Clauses that apply to them.
Question
Answer
Standard
Clause
I have been issued a defect notice from my
electricity distributor stating that the one
pole of my two pole private overhead electric
line only has 30mm of sound wood.
Yes, a private overhead electric line that is to be constructed or
substantially reconstructed in a hazardous bushfire risk area must
be placed underground. Substantial reconstruction means in case
of a private overhead electric line the replacement of more than 20
per cent of the wiring or more that 20 per cent of the poles in a line
supporting the wiring. The replacement of one pole of a two pole
overhead private electric line is 50 per cent and exceeds the
20 per cent.

No, all electrical equipment installed within the hazardous area and
all electrical equipment installed outside the hazardous area that is
associated with the protection of the hazardous area is prescribed

Am I required to issue a Certificate of
Electrical Safety for minor repair work such
as the replacement of a socket outlet or an
architrave switch?
Yes, doing minor repairs is electrical installation work, and the person
who is responsible for the carrying out of electrical installation work
must ensure that a Certificate of Electrical Safety is completed in the
required timeframe in respect of that work and give the completed copy
to the person for whom the work was done and provide a copy to ESV.
