Is this Aircon wiring install legal?

[EEVblog]

Hi
I asked this on my own forum, but someone pointed me here as a better bet.
I had a new 3.5kW aircon installed and was very surprised to find that it was just wired into the existing house 20A power point breaker.
We have 3 other aircons that share two dedicated aircon circuit breakers, so I assumed they would install another breaker, or at least share the existing aircon breakers.
The entire house only operates from two power point breakers, so a good majority of the house was already off this existing single 20A breaker now shared by the new aircon.
I measured the consumption of the new aircon at 1.1kW on full cooling mode (I have a solar analytics power monitoring system, which also has a dedicated aircon power measurement input that this new install bypasses by being on the power point wiring)
Also, the wire cores are hanging out of the box and the box is not secured.
I suspect they have done this because it was very convenient as our internal roof access ladder is right next to the aircon, as was the power point wiring, so they just spliced it in and job done. No need to pull a cable through the roof and install a new breaker.

So my questions are:
1) Is this up to legal NSW code?
2) If it technically meets code, is it a shoddy job that I should get them redo it with a dedicated breaker?

Thanks
Dave.

He has confirmed, its a tiny a/c unit , running current will be on the rating plate (hopefully) probably around 6Amps.

So what seems to be the problem?

You will need to take into account the starting current and size your OCPD accordingly I would suggest a D type OCPD for starters.

They're pretty much all inverted now Pete so no longer require C/D type devices.

Recommendation is that anything 2KW and above should have it's own circuit
