Is this Wiring Legal? (NSW)
<< < (5/37) > >>
Syntax Error:
That clusterfuk of an installation would be out of code in most national or state jurisdictions. I suspect the 'spur' cable is out of rating for that 20A circuit? And with exposed inners, the junction is no longer double insulated. I assume the screws in the box are tightened?

Not a certified Aussie sparks, but I might expect your AC had an independent circuit starting with an RCBO at the main board?

Back in the day, that box would have a big red DEFECT sticker on, put there by an angry inspector who learned his trade over 30 years. Not a two week course that covers why you should not really strip live cables with your teeth. Think yourself lucky the drongo didn't tag off the lighting circuit.

A rush job should still be a propper job. FAIL  :--
Messtechniker:
What a terrible job.

I also don't like the wood material this contraption
is resting on. It's a fire hazard should this be a
permanent installation. :palm:

SparkyFX:
Check the label closely. It is rated 3kW because it is pumping this amount of heat out of the heat exchanger (into ambient air). Electrically it is rated at 9 Amps.
Would not worry.
Refrigerator:
IMO that junction box looks dodgy as.

Hi All , Dave
I think you should find that Mitsubishi supplied a recommended installation leaflet with your AC.
 Any AC split unit requires that it can be Isolated for service.
Wiring it direct to the Mains without using ether via Plug to socket .
Must have an Isolation switch breaker . This is recommended as standard for all AC units.
 If its Hard wired  and have a fault requiring a service from Mitsubishi under warrantee .
 The service tech will not work on it and your warrantee will be null & void.
 
 I am now retired but I still hold a Full HVAC Licence  upto 800hp .

I would get that cowboy that did that work or Company demand that they send
 A certified Engineer / electrician back and ask to see his licence .
 Edit : it's also good practice that every AC has its own fuse .
