Electrical Question

Again, how does a rangehood draw that amount of current!
A stalled motor doesn't, the biggest lamps you can fit doesn't and the mcb provides short circuit protection.
As most have said - this is probably compliant but nobody is recommending it so if you are a sparky perhaps you should familiarise yourself with the act, regs and standards before accusing those who do actually know the rules as being cowboys.

100%

yeah I'm familiar with them,if you think that 1mm is good to take 32 amps and is electrically safe and compliant you are a cowboy and need to read the wiring rules,heard of discrimination!its about protecting the down stream installation via the circuit protection being the weakest link.its in the book.Ive had a single phase 500w water pump drawing 13 amps while it wasn't running,it had an internal fault to earth returning current through the earthing conductor,the fault had a high enough resistence not to trip the breaker.it had a 16 amp circuit breaker on it so was not tripping and the pump was also running fine,the only reason the fault was discovered was because the customer was getting high power bills,this had been going on for 2 months.if this was wired in 1mm it would have burnt out the cable real quick being a certain fire hazard.and you think this kind of wiring is compliant!you tool.

You obviously aren't familiar with the wiring rules but there you go again with the "cowboy" thing. The exemption you seem unaware of is 2.5.3.4(b)(ii)

For the third time, how is the range hood going to draw 32 amps!
Nobody is suggesting 1.0mm is good for 32 amps, point is it's not going to carry 32 amps and it's in a situation where it will either carry current within it's rating or in the event of a short circuit the MCB will disconnect the circuit. what part of this are you not understanding!

Regarding your 500w water pump, is it capable of overloading the cable (excluding short circuit) and the answer is obviously yes so no 1.0mm would not be compliant and IMO anyone even contemplating this exemption for a water pump should be kicked squarely up the arse.

Again, nobody has suggested this is good practice but the original question was "is it illegal".

Agree - and of course with the water pump example, an Earth leakage breaker would have sorted that pretty quickly!

how is a range hood going to draw current in excess of what 1mm can handle!thesame way in which the example i gave with the water pump,2.5.3.4 says "not capable of causing an over current"who,s to say a range hood can't draw an over current,I would have never thought a water pump would do this until I saw it myself,electricity does some funny things sometimes.at the end of the day the rules come down to interpretation,and your right everyone see's them different but the main thing I work by is "is the installation electrically safe".for me this kind of wiring wouldn't even be an option.good discussion though.
