WorkSafe - Energy Safety did something about this situation in 2021 and issued a prohibition on use of an adaptor/supply lead that allows a higher rated plug to be adapted down to a lower rated plug without inline protection. Sign up to the updates on their website, that's how they advise of things ...

I love the CD argument that you can get into with engineers. While a CD provides a bum cover for the electrician, the designer is still liable if the design isn't a certified design. Regulation 14 spells this out and its not an offence for being unsafe, rather an offence for not being safe! Therefor...

For a "tiny home" that's plugged in (16 or 32A supply), does the "minimum of two RCD" requirement apply in a transportable if there is more than one final subcircuit? (2.6.2.4(b)(ii) ) Ignore the label of tiny home. It depends on what the designer intended. If the designer of the electrical install...

I'm late to the party as usual. There is nothing in the ESR preventing an electrical installation on a boat that was built outside of New Zealand from existing and being used. It would need to be powered with US specification electricity to not be actually used or the use of the installation would b...

In AS/NZS 3000:2007 Fig 5.2 shows a HV Customer Substation supplying a Main Swb (no MEN link) are the conductors supplying this swb "mains" ? ESR reg 4 has the definitions of "mains" and "mains work" both refer to connecting the conductors to a MEN switchboard. If the POS is the substation then, no...

Have a read of the Electricity (Hazards from Trees) Regulations 2003 Schedule Growth limit zones for some more information https://www.legislation.govt.nz/regulation/public/2003/0375/latest/DLM233405.html https://www.worksafe.govt.nz/laws-and-regulations/regulations/electrical-regulations/electrici...

Hi, RCD feeding in RCD - discrimination Can we have a 30ma RCBO acting as an isolator feeding two other 30ma RCBOS(one for lighting circuit and one for PowerPoint) ? Cheers Take the type s out and throw them in the bin, they will likely never trip as the upstream one will trip first cutting the cur...

You must follow the cited standard. End of story. If you want to follow a newer version, you must first follow the cited standard. The way to do it in non-domestic is this: 1. do a clause by clause evaluation of the new standard vs the old standard, checking that there is nothing 'less safe' in the ...

Looks like an email to ES is in order. Thanks for your help Alec.

How did you get on with ES?

Hi, That is not a PSOA as it is non compliant. It is likely deemed unsafe by the ESR (based solely on the link you provided): Regulation 23(1)(g) of the ESR contains a unsafe provision based on a safety function that means an appliance cannot overload its plug. The use of this 'adaptor' allows the c...

Hi, There was no need, that I can see from your description, that you had to worry about the 1.5mm cable, unless the owner wanted you to (full rewire etc). Just because something exists in an installation doesn't mean that you have to upgrade it to todays rules. Unless it is unsafe, then the home ow...

But the fact of any change being made requires readers to put aside old interpretations, and take the revised clauses on their own merit.

Well said!

Put in a submission that it should be there!

Thanks AlecK thats what I thought. On its name plate they call it a "site box" and that it complies with 3190 and 3012. Unfortunately when I raised it with the manufacturer their reply was basically it has a SDoC and we have spent lots of money getting it certified not bugger off. I first saw it in...

Hi All Had an issue today on a new construction site of a large Retirement Village where the Building Inspector was quoting to our guys on site, the earthing requirements of AS/NZS 3000:2018 in regard to framing, in particular section 5.4.6, and what we should be earthing etc. His comment was that ...

In regards to this question I have tried to find the answer in previous posts but have not found but if iv missed it I apologise. Iv seen situations where main switches are not readily accessible for example a switchboard in a classroom needs key to access main switch A multi unit complex where a p...

My understanding is that all industry orgs have repeatedly sought & supported the updating of citations. 3years ago MasterElectricians put a lot of effort into providing a nationwide roadshow covering changes in 2018 edition of "3000"; in expectation that the ESRs amendment would happen as previous...

2018 is the newest version, but the ESR's cite the 2007 Version, it's good practice to use the 2018 version but there are a few instances where 2018 contradicts 2007, in those cases 2007 should be used. Hi, Sorry it is not good practice to use the 2018 version. a person would in fact commit an offe...

No its not an error. It is only intended to cover RCDs used for compliance with the ESR. It would not contravene the ESR if someone (PEW and license etc required) installed an RCD that is not Type A or not 30ma so long as it was not for compliance with the ESR. Look at the first part of the regulati...

ESR 23 includes a requirement that the voltage be "appropriately and adequately" marked; else it's electrically unsafe. Anything else would be covered by relevant product standard. Point being it's not our job to check this stuff. If it's a DMRA, then there will be an SDoC that states what Standard...

The regulations don't consider what they have on their web site, but rater what the product says.

Report it to Energy Safety and don't touch it.

Unless they are paying you for all your investigation and sorting out time?

If you use them for a 3ph load, then with one or two turned off, it could have up to 400V across it. And I guess technically, if one circuit breaker out of 3 on a 3phase circuit trips, it is breaking to an open circuit voltage of up to 400V. But yes, mostly they are used on single phase circuits, e...

If an RCD used in NZ is labelled as being Type AC, however passes a test when tested as Type A does it comply? 8.3.10.2 note 1 If the RCD being tested is marked with the symbol confirming that it is a Type A RCD, the residual direct pulsating current testing may be omitted. Is this note implying an...

IMO, as an inspector when we do an inspection the ROI details exactly what high risk work was inspected, the work inspected is also detailed on the COC issued by the electrician. I have always selected "part installation" when completing the ROI as the high risk work is just that - part of the inst...

Yip your correct.

But an iccpd isnt installed, it is just pluged in by anyone so not affected by that clause.

Hi, This is probably a bit late, Sorry but that's a mode 2 IC-CPD. (unless my Google search for the model is wrong, I remember Tesla originally made a mode 1 charging cable with a portable RCD inline.) Mode 1 is basically an extension lead that plugs into a socket outlet and then into a car - there ...
