Hi,
I've been asked by an Electrician who isn't part of this Forum on some advice for a project he is involved with.
It's a Mobile Installation for the Military. Basically a mobile Mechanics workshop / Mobile Tyre Changer to use during Military operations.
He is just making sure he is on the right track in terms of what standards to wire to.
The installation gets loaded on to a truck as part of a Convoy. If one of the Trucks get damaged / flat Tyre etc. then this 'Workshop / mobile Tyre Changer' gets unloaded from the Truck, along with a Generator as the Supply, then plugged in.
The Electrician involved is not part of the Military
The installation almost blurs the line between Installation and Appliance
I've suggested he follow 3000, 3001 and 3010. But it could almost be 3760 and the applicable appliance standard??
This one in question is going to Australia.
Also he has asked for a WoEF for the installation once complete - does it need one if it is for a Foreign Military? Does it need one if it is for the NZ military but not being used in NZ??
Thanks
Mobile Military Installation
Re: Mobile Military Installation
When it comes to mobile plant; there is a degree of overlap between two parallel pathways to safety compliance.
An item of equipment can be treated as transportable equipment, and ongoing safety managed via ESR 26;
or it can be managed as a connectable installation, under ESRs 60 and 76 - 78.
Depending on particulars, this may be the owner / operator's choice; however it isn't an entirely free choice.
ESR 26 provides pathways to fittings / appliances that are used by employees / contractors / occupiers of premises being deemed safe.
Nothing mandatory there.
But ESR 60 sets a requirement for anything that meets the definition of "connectable installation" to comply with Part 2 of "3000" and also with "3001".
And the WoEF aspects on ESRs 76 - 78 are equally mandatory.
3010 is directly mandated by ESR 60 for generating sets that are part of an installation and set up as mains-parallel;
but for plug-&-play use it's indirect, via requirements of (in this case) 3000 & 3001.
There's no doubt in my mind that this transportable workshop meets the definition of a connectable installation; and therefore ESR 60(1)(e) applies for the wiring installation.
Similarly ESRs 76 - 78 will apply if the unit is used in NZ.
Noting that all of this only applies in NZ; whereas each State / Territory in Oz has its own regulatory requirements (not all identical)
For example; my understanding is that in Victoria, wiring this unit would not even be PEW; their caravans being treated as toasters on wheels; all because they use a different definition of what is an "installation" and don't have any direct equivalent for our "connectable installation".
However despite this the Australian caravan construction industry is centred in Victoria, and they work to '3001'.
Word of warning: while compliance to '3001' will be accepted throughout Australia; they will expect it to comply with all the "Australia-only" provisions. In particular, all switches must operate in all live conductors.
Another difference between countries is in the supply lead plug (and the matching socket).
Similarly they will expect the latest versions of Standards to be used; as Standards come into effect automatically in Oz, a set time after publication (typically 6 months).
Details of any variances from what would apply in NZ should be clearly noted on the CoC.
WoEF on completion can be issued by the person who issues the CoC.
But WoEF isn't needed unless the unit is to be connected to a NZ supply (connection for purposes of testing is permitted by Electricity Act)
That said; any responsible operator will have their own systems for ensuring ongoing electrical safety;
