Thread: SAA Wiring Rules 2000. Current carrying capacity of cables.

For some days I have been trying to find this table on the 'Net with no success.

The range required is for domestic installations, 240 and 415 volts, 10-150Amps, enclosed and unenclosed.

If anybody knows of it would you point me in its direction, please?

The wiring rules are AS/NZS-3000, not 2000, which is why you maybe having trouble with the searching. The cable tables are found in AS/NZS-3008.

One of the cable manufacturers provides a useful brochure that maybe of use.

The table is probably hard to find due to a little thing called Copyright?

What exactly do you need to know OF? I have copies of both here.

Check to see if my second post in this thread gives you what you need...

Thanks, you blokes, for all your responses. Sorry I have not come back sooner.

chrisp, my 2000 was another of my, too many, Senior Moments. Thanks.

NC Archer, I am still licensed but retired, of course. A year ago, we had to move off the farm to be near an hospital, are living with a son. Our books are still in cartons.........somewhere!

A son and a grandson are licensed but are away on holidays and I do not like to go to their places and rummage round looking for their Rules books.

The Sub-mains here to the shed are 7/.036 which, in my day, was rated at 27 Amps. I was wondering what we would need to use if additional load were connected, say a total all up of 50 Amps.

From Table C5, it looks like 10mmsq will do the job.

A bit off topic but it interesting that we are forbidden from doing any electrical work yet over in the US they just have to take a short course and can then wire their house, plus their system is more complicated given they have a split phase 220V circuit and a 110V single phase circuit.

Given the price of getting an electrician (last one we had was $120 an hour plus travel) it might force people to do some electrical work of their own...

Not sure what 7/0.036 is but 7/0.37 is 1.5mm sq and rated to around 16Amps. 7/0.67 is 2.5mm sq and will do 27Amps in a pinch

From Table C5, it looks like 10mmsq will do the job.

Disregarding any derating 10sq mm should be OK.

Lets not go there RC. There's an ongoing discussion of this in the Renovate forum.
