16mm2 earth also needs to be used to earth conductive materials to the earthng point where an unprotected consumers main passes through any conductive materials . Actually i think it has to match the cross sectional are of the supply or something...(going from memory) unsless the cross section area is greater due to voltage drop.....
These new rules at leat have a index in them that helps not like th old 2000 ones
Maybe we need a new thread on the new wiring regs??
Yeah this IMO is going to cause a few problemsQuote:

Its going to cost he a new switchboard possibly $700 up-wards.
Or (as we where told) RCD GPOs but they still cost around $130
I know what the customer is going to say.
You could just add one RCD for that circuit, they only say you have to add it to the circuit you work on nothing about any of the others.Quote:

Gentlemen, I don't believe that the OP mentioned anything about additions or alterations. Nonetheless, if he feels that he may like to replace his distribution board, I could not find anything in the latest regs that indicates the need to purchase additional RCD's. Please note clause 2.6.3.4.
2.6.2.4 Arrangement.
Where additional protection of final subcircuits is required, in accordance
with Clause 2.6.3, the fin.....
2.6.3 Where additional protection is required.
2.6.3.1 Residential electrical installations.
Exceptions:
2. This requirement need not apply to certain alterations, additions or repairs in accordance with Clause 2.6.3.4.
2.6.3.4 Alterations, additions and repairs.
Socket-outlets that are added to an existing circuit shall be protected by an RCD.
Exception: The requirements of Clauses 2.6.3.1 and 2.6.3.2 need not apply to the following:
(a) Where socket-outlets or lighting points that are not RCD-protected are replaced, including the replacement of a single socket-outlet with a multiple socket-outlet assembly.
(b) Extensions to final subcircuits supplying lighting points only, provided that the existing final subcircuit is not RCD-protected.
The way I see it, even if the OP replaces his distribution board, he will not need to purchase & install any new RCD's PROVIDING that he is not in breach of any part of 2.6.3.4.
I am pretty sure that if he upgrades the switchboard you will find that he has to do so in line with the current regulations. So if he doesnt have enough RCD's to meet 2.6.4.2 then new ones will need to be purchased.
2.6.3.4 is only if he is adding to existing circuits not replacing the whole S/B... well that is how i interpret it anyway.
If I added a gpo to a house I would bring the whole house up to scratch or decline the job.
I dont do domestic work as Im firmly entrenched in constrcution.
I have fixed a few domestic houses but thats just me.
I started my apprenticeship in 1990 and that what I have always understood to be the deal.
Its no great loss if its only the circuit that needed be upgraded as Ive only done 2 or 3 houses.
I think its better that way anyway.
Gets rid off all these houses with old wiring and brand new gpos sitting on the wall.
Btw could a mod please cut and paste half this thread into a new thread named "aussie wiring regs"
cheers

As stated before and dont get me wrong RileyP I love finding out what other sparks do in their areas but local rules overwrite other regulations in some circumstances and if we started a blog on this you would have your every day joe blows looking up the regs then after reading and researching having the confidence to go and do their own work which is exactly what none of us want!<!-- / message -->
Yeah I was thinking about starting a forum site Just for electricians
The site would have to be password protected and members would have to prove they are a sparkie to get membership
Only problem is the cost of setting it up
Any thoughts
I agree totally local supply authority regs overrule as3000 but in general these regs are assosiated with supply and metering arrangements only.Quote:

I dont see why electrical talk regarding regulations has to be secret sparky business.
Anyone can buy as3000 if they choose.Its just whether they wish to cross that line.
The line is there regardless of how much they know and they know the line is there
Im allowed to read about woodwork and how to use a circular saw and nail gun.
I can go and build whatever I choose but bottom line is unless it has council approval its illegal ( when it comes to housing extensions etc.)Electrical work is no different. If someone chooses to read our wiring blog then gets electrocuted or wires up his brickshithouse its not the forums fault .Its his for not following the law of the land that states all electrical wiring work must be performed by a licenced electrician.
I understand your point about joe bloe and arming him with a wealth of information he may not otherwise gain but that is what the internet is all about...getting information you may never of had and its fantastic isnt it!
I dont think its the mods job on this forum to police what is said and not said about electical wiring work in Australia as long as we are not naming business's or particular people why cant we talk regs?
Im sure theres plenty of sites on the net on how to best grow dope or how to get the best kick out of whateva the kids are sniffing these days.... and no one is getting sued.
Its just freedom of information.
So can we talk regs in our own thread?
A simple no will suffice and Ill rest my case:C

Thanks all - an interesting discussion, but apologies if I only followed some of it!
No intention to add new GPOs etc at this stage. All I wanted to do was find out if it was three phase - which appears to be the case. I will get a sparky in to install the centameter at some stage.
Cheers everyone

Thought I would post an update for those who were interested.
I had the sparky around yesterday. It took him 1 minute to connect the centameter - instead of attaching to the powerboard on the inside (the bit I photographed), he went to the meter box, and installed it behind the meter. They only need to clip over the cables, not touch bare wire or anything.
The centameter is great - really useful for those who want to keep a close eye on energy use. Thoroughly recommended.

RCD on every circuit??? Hmmm has someone got shares in who makes these things!!
