Is this Wiring Legal? (NSW)

Also ask on electriciansforums.net if current code requires a local isolator for a new install of an aircon of the type you have on a dedicated circuit.

--- Quote ---4.19 AIRCONDITIONING AND HEAT PUMP SYSTEMS
Airconditioning and heat pump systems incorporating a compressor shall be
provided with an isolating switch (lockable) in accordance with
Clause 2.3.2.2, installed adjacent to but not on the unit, which isolates all
parts of the system, including ancillary equipment, such as head units, from
the same location.
For split system airconditioning units, where the manufacturer requires the
airconditioning system to be connected to the electricity supply by means of
a plug and socket at the internal unit, the isolating switch installed at the
external unit shall control the socket-outlet located at the internal unit.
For airconditioning systems (including room heaters incorporating a
compressor) where the internal unit (or units) are supplied from a circuit
separate to that of the compressor, a warning sign shall be permanently
fixed on or adjacent to the compressor isolator indicating that the isolator
does not isolate the ancillary equipment. Where the internal unit (or units)
are not connected by plug and socket, an independent isolating switch
(lockable) in accordance with Clause 2.3.2.2 shall also be installed adjacent
to each separately supplied internal unit (or units).
Exceptions:
1 The isolating switch may be installed at the switchboard supplying the
system if the switchboard is dedicated to the equipment (e.g. an
airconditioning plant room).
2 This Clause need not apply to unitary window or through-wall
airconditioners, nor to heat pump hot water services that are supplied
by a plug and socket-outlet installed adjacent to the unit.

@Monkeh: I belive you are correct.

I've just checked back - Dave's first post confirms its a split type, so the clause *DOES* apply.
However he'll probably feel the need for a locally qualified electrician to tell him that: *NO*, we aren't misinterpreting code, hence my suggestion to check back with electriciansforums.net.
tkamiya:
Again, I'm only familiar with Japanese code where I am licensed as an electrician and some of US code but not much.
According to my attorney in United States, my opinions doesn't matter but I need an "expert" testimony. I had to hire someone in the industry and have him tell me what's wrong. Then, court has an option to summon him to personally testify. Then and only then, we can prove the installer wrong. OUR opinion does not count in court of law. At least in United States, it does not.
This is my last post on this thread as there is nothing more for me to share anything useful. Dave, good luck.

I'd know something about the qualifications you're so proud of.
And I'm not colour blind - I know the difference between blue and green/yellow. You, apparently, can't see that - perhaps turn off the VPN so you can see the video at better than 360p.
This is perhaps a language barrier - that and an issue of assumption. You've seen some things which you assume are dangerous without knowing the context and are banging on your vaguely licensed drum about it. Me, I've seen a general mess which merits investigation rather than assumptions. But we both seem to agree it's an awful mess..

Ok yes maybe I few off the handle a bit . I have put another picture with 3 arrows .
the Blue wire goes to the tap up . were the other 3 green/yellow wire marry up under the tape .
The Wire is solid Blue . ..
Also the Bare wire live or dead should have at least have clamp protector on it

Dear Sir... you do realize don't you?? that the main objection to your 1st comment wasn't about the 'messy'
wiring, but your automatic assumption that 'Aussies' are slack and know nothing about rules!! :palm:
Yes, we often joke about 'our-selves' with our 'She'll be right' attitude, but that has NOTHING to do with our
knowledge, training & pride for the vast majority of us now/prior professionals! The same can be said for any
country. There are 'tradesmen', and then there are "TRADESMEN!" Just so that you know...
Our Old switchboards with the swinging Bakelite panels with often old original porcelain fuses & switches, often
custom mounted, WERE a bit of a rats-nest behind them. It didn't look 'pretty', but it was clear where each cable
came from, and the occasional loops that were visible & obvious. Now!... Even Australia!! (Who would have thunk
it!), uses modern modular panels/boxes, with modern breakers/main-switches/ELCB etc etc., with built-in Bus-Bars
etc. However, when new wiring is added to older premises, it is not Law to change to a new/modern panel, generally.
Old porcelain fuses etc MAY be changed to newer Breakers, and new Circuits MAY come in from either above or below.
Even if the main board is changed completely, often the 'old' wiring may not reach the 'new' Bus, Breaker-Strip. So it
is common to 'join' those wires, with a crimped (double crimped either end) connector.
I was/am a 'perfectionist' with MY wiring, due to my upbringing in the field, but in 'Static' (as opposed to wiring in an
aircraft or space-shuttle!) wiring, un-cable-tied wires un-seen, can be a blessing to follow!! :-+

Thank you but actually, no, Glenn, you don't speak for me or understand my objection at all.
