or if it wasn't and their contention tapping the socket circuit was legal is true, then what about the islotator they should have fitted if they were doing it that way?

They readily admitted they should have installed an isolator.

In this case with the new dedicated breaker I don't care for nor want an additional isolator.

.... so they've dunned you for the extra cost of the wire, which should have been largely or completely offset by the cost of the isolator they failed to install, and left you with an installation that may not even be code compliant.  :'(

Please at least tell me that either the breaker box is lockable with a padlock or the new breaker is lockable, so the aircon can be locked-out/tagged-out for service by a HVAC tech, without having to get a fully certified electrician in to isolate it.

Those breakers are all lockable.

No, they are refunding my install money.

No, it's not, and that's the same for the 3 other aircons as well.

The breakers are absolutely lockable. There will be a groove in the base of the lever when in the off position and two small holes on either side for fitting one of these:

Then there's this from a Western Australian A/C install company...

I was told that the way an electrical inspector (do they even exist now?) could tell if an owner did their own electrical work was how neat and tidy it was done.

Not easy, not hard, just need to be incentivised.

So if it looks too neat, there is a good chance the home owner did the job?  :-//  :-DD
I have seen cases where the so called professional electricians did a less than stellar job.
Here is an example of too neat of an installation that is totally wrong; just follow the wires to the conduits to see that each phase goes through a separate conduit.
edit: the inspector didn't catch this.

I have heard the exact same story in regards to a number of building processes.  Everything from electrical, to framing, to .... you name it.

The professionals know how far they need to go for the result to pass inspection - by the relevant authority.  The owner will want it "just so" and will take extra effort that a tradesman just can't afford.


A typical example I saw at Bunnings a few weeks ago...  You have your tradie who will load up 30 lengths of timber and only pass up on one or two that are significantly bent or twisted.  You then have a weekend warrior who will go through 50 pieces (or more) looking for 10, checking each and every one for straightness and defects, only going for the ones that look as perfect as possible.  The tradie will be in and out in 10 minutes while the weekend warrior could spend an hour puttering around.

BTW - these are framing timbers I'm talking about.  Not gonna see them when the wall sheeting is affixed.
