Two pin to UK Three pin plug adapter ?

[Rich_13]

I have a battery charger with a European 2 pin plug fitted . I have just noticed that the three pin plugs on other appliances I have are actually adaptors which accept the two pin ones inside and the pins locate in the live and neutral terminals .
How do I identify the positive and negative pin on the european 2 pin plug on the charger so I can fit it the right way ? There's a "N" and a "D" on the plastic plug , I'm assuming that's neutral.
Also what fuse would you use , the appliance manual says 3 amp, if a 13 amp BS1363 and 5 amp for "other" types of plug ?
Thanks

which country are you in, and which country did you buy the charger in?

Is it a phone charger or a car battery charger?

Is it a cheap thing off a market stall?

There is no such thing as

positive and negative

in AC circuits!
The pins can go either way round.
If manual says 3amp fuse, then 3amp is what you should use.

It's a car type 3 stage charger . I'm putting the attached 2 pin plug into the 3 pin for use here in the UK. to use manual says to be connected to 240V 50Hz . The 3 pin plug is the type that opens up and you place the 2 pin one inside locating the pins in the live and neutral positions .

Thanks , My Dad thought that was the case , but I like to be 100% sure , I'm scared of electric ! ( and fire)

photos would help a lot.

If you're using it in the UK, cut the continental plug off and fit a UK 3-pin plug instead.

What country did you buy it in?

"Responsibility for fitting a standard plug or converter plug will fall to the first supplier of the appliance in the UK."

Bought it here It's off ebay but UK supplier despatched from UK .
My first thought was to do what you said actually until I realised when I looked that a lot of stuff ,including another charger I have ,has the these converters fitted and I had one spare . Yeah it should have had the thing fitted and I contacted them about it ,
I remember when everything you bought came without a plug and you fitted it yourself with the correct rated fuse , dead straight forward .

While that is the best option some of the cable used has such fragile wire that making a good connection in the terminals of a UK 3 pin plug requires some re-inforcement of the wire.

To comply with the law a UK supplier has to either fit a UK plug or attach a converter, supplying a converter socket does not comply, it needs to be fixed to the original plug, so the converters you are looking at are a way around the law, rather than some thing strictly required. If the suppliers cuts off the plug and replaces it, he needs to show the staff used is qualified to do the work, but using the adaptor gets around the problem, they simply can't be fitted incorrectly, so skilled staff not required.

Because I worked around the world I liked the adaptors, easy to remove when I went abroad, however your unlikely to take your car battery charger abroad so cut off the original plug and fit British is likely best option.

The type C plug is rated at 2.5A in Europe, so 3A fuse is ample.

I have two options there , the adapter is the quick option there , fitting a plug would be no problem either (does that make me skilled staff ?)

I think it is one of these:

I have a battery charger with a European 2 pin plug fitted .

So have I.

I have just noticed that the three pin plugs on other appliances I have are actually adaptors which accept the two pin ones inside and the pins locate in the live and neutral terminals .

Like my pictures?

How do I identify the positive and negative pin on the european 2 pin plug on the charger so I can fit it the right way ?

Line and neutral, as has been said. It doesn't matter which way round.

There's a "N" and a "D" on the plastic plug , I'm assuming that's neutral.

I don't know about that.

Also what fuse would you use , the appliance manual says 3 amp, if a 13 amp BS1363 and 5 amp for "other" types of plug ?
Thanks

Here again, it doesn't matter.

It will only have the protection from a 16A MCB when used in Europe.

Yeah It's the same adapter as the one above
