No Australian standard covering inverters
...that is absolute rubbish.
There may be no specific standard that apply to inverters
But there are plenty of standards that apply to ALL 240V electrical items.
To start with AS3100 Approval and Specification-General requirements for electrical equipment.
While not specificaly written for inverters
it will have application in much of the machines design.
From the preface
"This standard contains general requirements for electrical equipment and can be applied to equipment for which no particular Approval and test specification exists. It also forms the basis of general requirements where an Approval and test specification exists for a piece of equipment. Only safety matters and related conditions are covererd."
AS3760, "In-service safety inspection and testing of electrical equipment" could be applied to an inverter that "is already in service, has been serviced or repaired, is returning to service from a second hand sale or is available for hire"
AND the same or similar procedures set out in AS3760 should have been conducted prior to leaving the factory.
AS3000 known as "The Australian wiring rules" specificaly mentions inverters
and how they should be connected and earthed.
While it does not specificaly mention inverters
AS61558, "Safety of power transformers, power supplies, reactors and similar products"
Could easily be considered to apply.
The scope specificaly mentions "switchmode supplies" which is exacty what an inverter is.
The fact that extra low voltage DC is on the input and 240V AC is on the output rather than the other way arround changes nothing.
The 3 pin outlet socket used in the unit will be a prescribed article and will be covered by a standard
If there is a circuit breaker or a residual current device on the 240V side of the inverter this may also be a prescribed article and be covererd by a standard.
Then you get into the endless minutia of the standards that apply to all the components...even the "standard test finger" used to see that the vents or grills are not too big will be covered by a standard
Even if the standards dont specificaly state that the inverter is covererd by a standard, state and federal legeslation will.
The QLD legeslation is especillay agressive and uses words like "binds all" "free from electrical risk", "duty of care" and realy hammers home the "chain of responsibilty"....that is one piece of legeslation you don't want to be on the wrong end of......it allows them to kick you turn you arround and kick you again.
In court, even if you could argue that none of the standards directly applied (not likley), the the concepts of "duty of care" and " freedom from electrical risk" would mean that the general expectations of safety and suitability in AS3100 would be used to prosecute the whole "chain of responsibility" from the owner and operator of an inverter right back to the importer.
OH and then you move on to the " electromagnetic compatability framework" which specificaly mentions the like of inverters
, dimmers and switchmode power supplies and puts them is a catagory of their own.
So don't tray and piss in my pocket and tell me its raining.
