Posted By Topic: test and tag a battery drill charger

Sep 11 2019 12:01

Asked to test and tag a charger , There is no identification of voltage or insulation class. Looks to be double insulated ie only phase and earth on plug . is a information sticker necessary or needed ?

Sep 11 2019 12:28

ESR 23(1)(a) requires (input) voltage marking.

Sep 11 2019 12:29

and i presumed you meant "phase and neutral" not "phase and earth"?

Sep 11 2019 12:38

yes ,sorry phase and neutral .
Thanks again for your help and information

Is that the same for Australia?

Hi Peter

In order to "pass" an item under 3760 in either NZ or Aussie version of the standard, clause 2.3.2 Inspection, part (i) Check that the current rating of the plug is consistent with the current rating of the item.

You can only do that if the rating plate/label is fitted to the item. In NZ, the presence of such a label/plate is a legal requirement,not sure about Aussie/Various State requirements

look very carefully on the plastic housing. Often there's microscopic very faint writing (at least with my eyes)as part of the casing. Or printing 1 shade different to the plastic colour. Try looking for the details on an iPhone charger.

Class 2 appliance must show double insulated symbol on appliance label, Class 1 will not have a symbol.

Voltage, Load rating of the appliance also required to be on the appliance label.

Thanks every one for reply's . Looking difficult to get a test report or voltage sticker for this charger , we can get a 110 volt american charger with all correct labels . Can i test and tag a 110 volt rated charger and supply with an step down transformer .

Short answer: No.
maybe can get through under "3760"; but you won't get it past ESR 23, because it will have a plug that doesn't comply.

Thanks again , to get this OK to sell can we get a dc power supply that we can test and tag , then introduce the say 14 volts to our charger at the correct point within the charging control circuit ?
Clutching at straws here , but ?

Is it something you can contact the manufacturer. Some brands have the label as a spare part.

Sep 23 2019 14:46

still trying to get an answer from manufacturer, however , are we able to sell a 110volt charger and include a 110volt isolating step down transformer or a power voltage adapter ?
Thanks again for help with this

Looks like i already asked the question earlier , is there any way to sell a 110 volt charger ?

If it’s a transformer inside find out the secondary voltage and current on load. If it goes through a rectifier get the DC values as well. See if you can get an off the shelf power pack AC or DC to suit and fit a socket to the charger to suit the power pack. Then just tag the power pack. If it’s a switch mode power supply it may make it a bit harder to work out.
