Posted By Topic: ESC for appliance repairs

Aug 09 2013 12:41

Im sure this has been asked before but I cant find it..
Is a ESC required for appliance repairs or are they covered by NZS 3760 ??


Aug 09 2013 12:48

ESCs are for installations, not appliances (ESR 74A).

Thanks 3760

If completing \"electrical\" repairs on an appliance, the correct standard to test it to, is AS/NZS 5762, not 3760.

ASNZS 5762 provides specific guidance regarding the VISUAL INSPECTION for certain items being repaired. All other testing is completed according to ASNZS 3760.

Are you sure Rob??? Regulation 90(2)(iii) would tend to say otherwise.

3760 is for \'in service safety inspection\' i.e. periodic inspection, not testing after repairs. 5762 is the correct standard.

Rob is correct if you read 5762 you will find that it tells you to carry out testing in accordance with 3760.

More dumb rules.... 5762 is the mandated standard in the regs, but the mandated standard tells us to use another standard, 3760, to do the test... What flippin brain surgeon came up with that one ???

ASNZS 5762 extends the testing procedures prescribed by ASNZS 3760. It includes such things as checking that the repaired item hasn\'t been recalled and verifying that thermostats and cut out switches operate correctly.

Do we have to check that the Microtemps work, also?

download the Standard and have a read

Do appliance repairs/maintenance need to be done by a licensed person or can they be done by a competent / service person (as the testing can be done by competent person as per 5762/ 3760 ? would a battery charger, solar controller or inverter be classed as an appliance ?

Standards generally refer to "competent persons", rather than to licencing or other qualifications that may vary from state to state.

Who can do what is governed first by Schedule 1 of ESRs, which defines what sorts of work are PEW; and secondly by limits of work for various classes of licence.

Definition of "appliance" is in the Act (there's a pointer in ESR 4); and none of those things would meet the definition because they don't "use" (consume) the energy. What they are is electricity converters.

Maintenance / repair would generally fall under clause 1(b) of schedule 1; as they are "fittings" that are intended to be connected (by either fixed connection or detachable connection ) to conductors used in installations. Same applies to isolating transformers.

Except that many solar controllers would be operating at ELV, and repairing those generally would be not PEW under clause 2(b), (c) or (d).

Note that "3760" does not talk much about "appliances", it covers inspection of "electrical equipment".

As Alec said ... ...
A "competent person" can't do repairs to electrical equipment unless they are licensed to work on that type of equipment.

Feb 25 2019 15:42

clause 2 (d).
Does that include a battery charger that plugs into a 230V socket to charge a battery?.. providing work can be done without exposure to LV parts or is it only for items with ELV supply such as an inverter? .. as it mentions appliances which generally plug into 230V cheers

It says:
..but only if the work can be done without exposure to live parts intended to operate at voltages exceeding extra-low voltage:

That doesn't mean that the parts are just isolated, it means that you can't have access or exposure to any of those parts.

So for example on an appliance - you could replace a hose on a vacuum cleaner - but you can't repair the spring on the cord rewind, because you would have to access a space where those parts intended to operate at low voltage are.
