Latest news coming from Standards NZ should come as no surprise. They've released a heck of a lot of Standards under the guise of being "currently-under-review". It's a common ploy (plot?) for them to publish so many, some quite controversial, during the holiday period. It's refreshing for this cynic to note the closing date for this round of submissions is the first week of February.
And for those of us who issue warrants for caravans and motorhomes there will be interest in the caravan gas installation standard AS/NZS 5601.2. currently under review. It's primarily a GAS standard however it contains electrical topics we need to be aware of. It covers such matters as the use and requirements around encapsulated electrical devices (min IP55), general electrical compliance requirements, safe discharge of static electricity, electrical safety bonding, requirements for electrical isolation in line with AS/NZS3000. It also describes that piping can't be used as an earth for any electrical system, cylinder lockers must not contain electrical equipment other than a gas safety shut off valve that is encapsulated, safety shutoff valve wiring must be double-insulated, and the biggie... electrical equipment, batteries or ignition sources must NOT be installed in the cylinder (and/or storage) compartment. Did you know that (gas) piping must be separated from any electrical service by at least 25mm irrespective of voltage? And that rigid piping must be at least 100mm from exposed live parts of electrical fittings.
Energy Safety have provided a link in their latest online safety mailout so you can sownload a copy of the proposed draft.

In their latest mailout they reintroduce Claude their safety spokesperson; oh alright it's a blimen cat and not a very good looking one at that! He's running a competition with a couple of bbq's as prizes for people who correctly identify dodgy gas and electricity use.
They also make available a draft copy of AS/NZS 5601.2 which contains subtle yet very important information which, in my view, will be very important to the electrical inspection sector.
There's also an update on AS/NZS 5139 and although currently not cited in the Regs, we are reminded that such work will become high-risk PEW. This standard is about the Safety of battery systems for use with power conversion equipment.
