Upside down Australian Circuit Breakers
I always thought that the story about things being upside down in Auz were simply that, a story. However I now have evidence that it really is so.
Only kidding please take a look at the photo. See how the CB's are all upside down. And I have seen this on quite a few jobs here in Auz. Does anyone know why? I have asked various people the whipper snappers have no idea and just shrug their shoulders. "She'll be alright" as they always say down this side of the world.

Re: Upside down Australian Circuit Breakers
Hi Mate,
They sure went to some effort to put those circuit breakers that way.*
The only reason I'd suggest that they would put them that way is so that the operation is similar to a household light switch here in Australia, up being off & down being on.
One way or the other - at least they are all in the same orientation!*

Re: Upside down Australian Circuit Breakers
Turn the picture 90 degrees to the left, and you have a vertical switchboard that makes sense.
To the optimist, the glass is half full. To the pessimist, the glass is half empty.

Re: Upside down Australian Circuit Breakers
Hello Mikeref it is not a verticle board the orientation is exactly as shown no trickery. The closest answer is possibly the switch orientation with down being on. The whole 3 floors of the building are like this and the building is only around 10 years old. It must be an ACT thing.

Re: Upside down Australian Circuit Breakers
prob coz its easier to lock the breakers onto the din rail if its adjacent the busbar- prob cables too short to feed the top of the breakers with the busbar underneath the breakers-ps acu1 3rd phase is red instead of blue and the red phase incomer is showing copper strands-req reterminating-also no sheild on the incoming

Re: Upside down Australian Circuit Breakers
Well I guess they really wanted the bus bar on top and circuit wiring underneath for some reason. Maybe to make it look neater ? An apprentice snipped the wires off to short to reach the top?

or he wanted a good weigh in-but was unable to stretch the cables-or it was his last week on the production line and wanted to throw a few spanners in the works

Re: Upside down Australian Circuit Breakers
im with mike on this..
i cant recall ever seeing any breakers upside down (unless on a vertical din rail.. ive seen them mixed around in that instance) on a horizontal board.
they should be mounted up the correct way so its easy to turn the breakers off - quickly pull them down to break the circuit. i cant see any advantage, even with busbar, to have them one way or the other - it shouldnt make a difference.
ps. shielding? you pommy sparkies are odd, ive got one from birmingham and he is always banging on about steel conduit this, steel conduit that...

Re: Upside down Australian Circuit Breakers
Turning the picture 180° doesn't help unless p'shopping the stickers.
Anyway, I don't think there's anything wrong with a breaker upside down. But the electric arc floats upward before extinguishing, so in this case it goes to output, which is dangerous for the load.
