10amp vs 15amp power supply

I currently have a gas-cook-top free standing oven with an electric; grill, light, starter and fan which has 10amp plug-in supply.

I intend replacing it with a duel-fuel oven which requires a 15amp socket (ie. no need for hard wiring).

I presume my wall socket is only 10amp.

Can I use an, ‘Arlec 10A to 15A Compact Single Power Adaptor PB92’ or will I have to have the whole circuit wired back to the Board.

In have no intention of carrying out the work myself. The gas fitting I understand, I just want to know what electrical work may be involved.

Welcome to the Bunnings Workshop community @PeterHart. It's brilliant to have you join us, and many thanks for your question about 10 and 15amp sockets.

I would recommend you have an electrician install a 15amp socket. The Arlec product has a maximum current rating of 10amp. Basically, this means that it allows you to plug your 15amp device into a 10amp socket, but if the draw is too high, it will trip the overload protection in it. Devices are equipped with a 15amp plug for a reason, and that is because they have a higher draw.

There might be situations where there's a 15amp device with a low power setting mode, and this device would let it run on a 10amp circuit. So, hypothetically, if the hotplates are electric on the new cooktop, the Arlec product might let it run with three plates on, but it you turn the fourth on, it will trip because there is too much draw for your 10amp circuit. The overload on this device will simply trip instead of the one on your circuit board.

Unfortunately, this device doesn't allow you to run 15amp devices on a 10amp circuit, as it would appear at face value. It's catering to what I would believe to be a relatively small amount of devices that are equipped with a 15amp plug, that don't actually need to be.

Let me also add a couple of our electricians to the discussion to see if they might like to add their thoughts: @MikeTNZ and @CSParnell.

Please let me know if you have any questions.

I’ve just answered my own question re. ‘Arlec 10A to 15A Compact Single Power Adaptor PB92’.

I thought it was too good to be true.

Yes, it will plug in, but when the Oven draws more than 10amps, the Circuit Breaker will trip, so this Adaptor will not solve my problem.

‘Back to the drawing board.’

Hi @PeterHart,

The only difference between a 10 ampere socket-outlet and a 15 ampere socket-outlet, is the size of the Earth pin on a 15 ampere socket is larger.

The actual Phase and neutral pins are effectively the same size in both configurations.

You can plug a 10A plug into a 15A socket, but not the other way around, if that makes sense.

Personally, I would prefer that you have an electrician replace your 10A socket (if that is what it is) with a 15A type and at the same time they will check to see that the wiring and circuit protection is suitably rated for this change.

I hope this helps,

Cheers,

Mike T.

Hi Mitch.

I bought a heat gun 1800watts comes with 15a plug but at home I have all 10a socket. Can replace the 10a with 15a GPO. Do these heatgun takes 15a. It has got 3 level controller. If use it level 1 or 2 which is less power should not be issue. If I exceed the 10amp mcb will trip. Please advise what are my options. Also 10a and 15a plugs are same with load carrying capacity except pin size.

Hi @Sajidsohail,

I've spoken to Bosch, and it appears that the unit is only distributed overseas. The Australian version (Bosch Professional 2000W Corded Heat Gun - 06012A6240), which is actually a high-capacity, does not have or require a 15-amp plug.

I suspect the plug you have is an overseas variant and not an Australia 15-amp plug, though it might look the same. In this instance, you would need to speak with an electrician about the possibility of converting the plug or plugging it into a 15-amp outlet.

Please let me know if you have any questions.

Hi @Sajidsohail ,

That is rather strange, given that most plastic heat-guns are double-insulated (look for the square within a square symbol on the nameplate).

This means that it doesn't require an Earth pin on the plug, because there are no exposed parts that could become live under normal conditions.

Given that this is an 1800 Watt heat gun, you're looking at a current draw of about 7.5 Amps, it should be fine to replace the existing plug-top on the heat-gun with a 10A type, if you don't feel confident doing this yourself, enlist the services of an electrician.

I hope this is of some help.

Regards,

Mike T.
