Pat testing issue

[westward10]

So the plug is not the part of the appliance???
Is your leg part of the body ???

Depends how you look at it, the appliance is tested for Class II requirements but the plug falls under different standards and is not a Class II part whether the appliance it connects is Class II or not.

A class II appliance could be fed from an FCU. By your logic the FCU shouldn't gave an earth.

But this is not mobile appliance.

No but it may be subject to routine inspection and treats.

So for me mobile appliance should have exactly have exactly the same wire as it left the factory. Fully moulded plug with cable.

Not necessarily things get damaged and replaced. A non factory fitted cord and plug does not necessarily mean the appliance is no longer fit for purpose.

Lets suppose your Class11 appliance had a moulded plug with a plastic earth pin, and unfortunately someone stood on the plug and the earth pin snapped off. It's going to be tricky plugging it in to some sockets. Do you throw the appliance away, or put on a new standard plug with an earth pin?
The latter, methinks.

The amount of broken off plastic earth pins I have had to tease out of a socket.

But I am thinking only about The class II appliance.

I'm not really sure what you mean. Are you testing these appliances?

 

[DPG]

The appliance is still class II. There is no earth connected in the plug and there is no earth wire in the flex.

this thread seems to be getting lost here.

A class 2 appliance is double insulated, therefore not requiring an earth.
it is still class 2 if there is an unused earth pin in the plug.
it is still class 2 if there is an earth in the cord set that is not used.

it only becomes class 1 when there is a metal surface that could become live under fault conditions therefore requiring an earth.

this is so simple I am amazed it has had over 30 posts.

some class 2 items have exposed metal components that are not earthed.

What is a "mobile appliance"?
The common types of equipment within the 4th Ed. CoP are, "portable", "movable", "hand held", "stationary" and "fixed"
And what is your appliance?

 

[Timbo]

After a lot of hard work reading this thread, I have come to the conclusion that we need the "dumb" button back.

Your over thinking this, you have had plenty of replies fella, I assume you have had your answer, just not an issue

Can you still get Bonios? I remember them from my childhood when we had a Golden Retriever, and I quite liked to nibble a Bonio...

 

[telectrix]

arrrrghh. the pirate has turned cannibal. typical.

 

[Lister1987]

Didn't need replacing because it had a plastic earth pin.

If I cpd o would replace every sodding plastic earth pin with something more durable, always seem to snap the buggers 0ff....
