Small submersible pond pump

[foxhole]

Mains 240v two core cable , unfused, safe? ( from China of course ) was going to cut of plug and replace with standard 3 amp fused 3 pin plug.

Piece of string 10 pound weight safe? I can't think of any way you can supply an item without a fuse, be it in a fused connection unit or a 13A plug, and as long as the supply is RCD protected then the RCD should disconnect before any danger is present to humans, not so sure about fish.

But should have the class II sign,

if not then likely not safe.

What is the plug you are going to cut off?

 

[fluorescence]

One without a fuse in it.

Yes just chop it off and wire a standard UK plug onto it.

I know it has not got a fuse, but what type of plug is it? European, American, Australian, or perhaps an illegal unfused square pin plug.

Are you certain it is just a plug and not a very compact Switch Mode Power Supply feeding the pump with an Extra Low Voltage supply ( typically 12 or 24 volt )

Some of these very compact SMPS "plugs" are smaller than a normal plug and not all of them are labelled as being an ELV power supply.

No , 2 pin basic unfused plug , unit label 240v.

Something like this would normally be 'potted' to make it waterproof. See if you can see the flex disappear into a block of resin with no other visible wires, connectors or anything else that looks like like it could become live. If so, it's probably reasonably safe as long as it's connected to a RCD.

Yes , resin bound .

It will depend on the nameplate rating as to what size fuse to fit in the plug. 3A may be too small to cope with the current inrush unless you specify it's for a small pump motor and therefore need a 'motor' fuse.

One of my customers buys cheap hand driers from China complete with UK plugs, unfused of course

Yes you can snap the earth pin off with a push of the thumb.
