Question Answer Standard/Clause
I have not wired a new home,
including a new meter and
switchboard before. I understand
I have to put the installation or
connection date on the switchboard.
Is this correct? Yes. The date of initial certification of an installation shall be
available on-site, by permanent, indelible marking on or at
the main switchboard. AS/NZS 3000:2018
I have just employed a second year
apprentice electrician. What type of
work can second year apprentices do,
and how much supervision do I need
to provide? It is now a requirement under the General Regulations that any
person who employs an apprentice must ensure that the apprentice
is given effective supervision in accordance with ESV’s published
Apprentice Supervision Requirements.
Note: In order to enable re-verification, it is necessary to know
the details of the original verification. This will simplify the process
of re-verification, when set up.
This requirement extends to any licensed electrician or licensed
electrical switchgear worker who has been tasked with supervising
an apprentice who is carrying out electrical installation work.

I have installed wiring in the walls
and ceiling in a domestic installation.
When assuming that thermal
insulation will be installed in the
future in ceilings, walls and under
floors, do I consider wiring is ‘fully
surrounded’ or ‘partly surrounded’
by thermal insulation with regards
to de-rating the wiring’s current-
carrying capacity? In most circumstances ‘partly surrounded’ would suffice as the
wiring is often clipped to building members or laid on building
surfaces. However, where it is clear that wiring will be fully surrounded
by thermal insulation if installed in the future, the appropriate de-rating
factors from AS/NZS 3008.1 must be employed. AS/NZS 3000:2018
I have to install a battery system that
is associated with a solar system. Any battery energy storage systems and their associated battery
systems, as defined in AS/NZS 5139, must be installed to comply
with this standard. This standard applies to battery systems that
normally operate between 12V d.c. and 1,500V d.c., and are
connected to one or multiple PCEs. Electricity
What standard do I need to follow for
the battery system?
Clause 3.4.1 (Para 3)
All other secondary battery systems, as defined in the scope
of AS3011, installed in buildings, structures or premises such as
those with critical power continuity requirements (e.g. Telecom,
UPS, hospitals, sub-stations and black start) outside the scope
of AS/NZS 5139 shall comply with AS/NZS 3000 and AS 3011.
I install switchboards on domestic
building sites that are used as the
builder’s power supply and then
converted to the permanent power
supply. Typically referred to as ‘temp
in perm’. Yes. All switchboards or metering enclosures newly installed on
a construction or demolition site must meet the requirements of
the General Regulations. This requires the switchboard or metering
enclosure to be securely attached to a pole, post, wall or other
structure that is rigid and secure, or otherwise be securely fixed
I understand there are some new
rules regarding these types of
switchboards. Is this correct? Where the switchboard or metering enclosure is supplied via
underground consumer mains, the underground consumer mains
must be enclosed in compliant heavy-duty non-metallic conduit.
Furthermore, the consumer mains and compliant heavy-duty
non-metallic conduit must have additional mechanical protection
of WSX3 from the point at which the consumer mains exits the
ground up to a point that is within 100 millimetres of the point
at which the consumer mains enters the enclosure.
