the way to fix it is :- first off check that all the terminations are secure as a loose connection will give a bad test, then :- Change to a B type trip curve MCB or reduce the circuit breaker size, for example a 20A circuit breaker, reduce to 16A, you may need to go down 2 sizes or Upgrade the size...

I have noticed that some N & E bars are numbered, would this meet the requirements of identification?

They show up for me in that topic, not sure why it's not working in this particular topic

it's not available on the 1st post to a topic, but I can see it available on your reply to this topic

This would be a mode 1 charger, the "Guidelines -1.3 General requirements" issued by worksafe state a "A-Type" RCD, Mode 1 charging outlets must only be installed in a domestic or similar installation. Remember these are guidelines and a good set of instructions to follow but they are NOT cited stan...

DougP has suggested that we implement a favicon - you know the little symbol that comes up in your web browser next to the URL that symbolizes the web site. Good idea Doug, now we just need some smart people to come up with a design, lots of smart people here, so people put your brains in to gear an...

2.3.3.2 says that domestic installations shall be provided with not more than one main switch for (a) each separately metered supply or (b) where there is more than one separately controlled supply from meter, a main switch for each of the separately controlled supplies. So for a domestic installati...

Problem sorted, now 12kb, if you need more let me know

When I was doing that kind of work we would label each phase/neutral/earth with a slide on label at the termination point, came across heaps of commercial panel that had absolutely no circuit identification, it made for a real nightmare trying to identify the corresponding neutral and earth for each...

here is the actual guidelines

I think this is more aimed at switchboard rooms been re purposed as a storage room/cleaners room etc.

Never used one, but from what I understand they are usually rated for 100mA and suited towards the protection against fire. They are not suitable for personal protection (like the A, B, II type) as they have a built in time delay to allow for nuisance tripping.

Greg, how do you go about getting fiber ducting free of charge from the wholesalers? Walk in to your regular wholesaler and ask, they usually have them. I have got them from JA Russell, Ideal and Active, depending on demand they may have to order in. They should also have available the indoor fiber...

At what point does work on PV (Solar) become PEW, disregarding any inverter that may be attached to the PV array.

A couple of examples,
1) a PV array on a house charging a bank or batteries.
2) A PV array on a camper van

In a non-domestic installation what other situations would call for multiple main switches?

In a commercial building where there are multiple tenancies, typically a main installation switchboard which may or may not have metering for each tenant.

Can conductors within a multi core cable smaller than 4mm², be used in parallel? Such as a 2.5mm² 4c+e used with two sets of parallel conductors. 3.4.3 says "Current-carrying capacities for circuits comprising parallel multi-core cables or groups of single-core cables...." To me, that means paralle...

Thanks Alec, you're right about "there is a main earthing system".

I've seen plenty of these water pipe main earths, usually a ratty bit of bare earth - around 2.5mm (but the old imperial size), Our policy when doing ohug's is if it is a water pipe style earth, to upgrade it.

I have done a lot of this kind of thing in Auckland, but more recently on the Waikato area, Usually it is done entirely at the property owners expense. The electrician generally runs the new wiring for chorus from the demarcation point to the nominated point outside the property line, Chorus will do...

Here is the most recent copy of the EV charging guideline that I have.

Please remember that these are "Guide lines", they are not a cited standard or legislation, but they do make a good starting point on what to do.

What was the name of the standard?

There are a couple of ways to work this out. From Table C2 in AS/NZS3000:2007 or by measurement, you could do some load checks throughout the day to get an indication on the loading, or hire a test instrument (Tech Rentals for example) and hook it up and let it run for a week and from those readings...

1) Generally speaking 63A is the size supply authorities give for domestic installation. but without physically checking the fuse size in the pillar/pole there is no way to be 100% sure 2) No particular reason i know of for a switch been used instead of a MCB, no reason why a 2 pole MCB could not be...

I think we just let them get on with what they are doing, I tried helping them out a while back with their forum but it was ignored. Time will if facebook is the way to go or a traditional forum is the way to go.

Hi Craig, there is a Metering and Network forum, I'll add distribution to the name of this

Thanks Doug, you help is appreciated

Came across this a little while back, have a read and tell us what you think

Suggest here for new forums, There is no guarantee that the new forum will actually be created, but it's a starting point.

We will play the wait and see game, if spam becomes a problem i'll place posting approvals on new joiners.

As for the spell check, not sure where that is set up

Good idea Doug, i'll add those groups shortly. I think I have switched off approval of new postings, but give it a go and see

Hi everybody, Welcome to the group, Hopefully someone with a bit more knowledge than me will point me in the right direction on importing the old forum posts, but for now i'll kick this off. future plans, for now I don't mind approving new users and playing moderator, as things get more busy I may a...

Hi everybody,

I have a copy from the wayback machine of the electricalforum.co.nz and would like to get this in to these forums, anyone know how to do this?
