Extention Lead

  • Thread starter Thread starter hlb

Many of the B&D extension leads are intended for use only with "double earthed" ( prolly the incorrect term ) applances - such as there lawnmowers.
 
Safe for items that are 'double insulated' and have no Earth - as mentioned by Pinnacle. Lawnmowers, hedge cutters etc. I'd always use an earthed extension lead - especially if using power tools or similar. An RCD plug on the end is also a good idea - especially outdoors where it might save your life in the event of a fault, cut cable etc.
 
Why would an extention lead have no earth wire?

It's made by Black and Decker.

Is it safe?

Line 2 answers Line 1 ;)

Line 3 - No.
(OK it's been answered). An additional point is that the current rating is also low - about 5 amps.
To be fair to B&D they are only intended to run their equipment, whose power load is only about 500W. Probably fitted with a 3 amp fuse.
 
When using it, you need to look at the appliance where the bumf such as wattage and voltage is moulded.

If you see a symbol of a square inside another square denoting double insulated appliance, it is safe to use, if the appliance does not have this, do not use with that extension cable.
 
No, I got lost and posted on the wrong forum.

What a silly and dangerous lead to make. Who the hell looks before plugging whatever in.:confused:

Not dangerous if used as intended as said for doubly insulated tools etc.

The two I have are not extension leads as such but leads with two pin sockets which can therefore only be used with appliances that have the matching two pin plugs. Two pin plugs are only fitted to doubly insulated tools. Therefore not possible to plug a piece of equipment requiring an earth into them.

These are sneaky, three pin sockets on each end, but two wires in between. AFASIK. All English plugs are three wires. Am I now expected to be an electritian to use an extention lead.

The earth pin on some of these extensions is plastic so a none conductor.
It is there to open the protective shutter grid on a 13amp 3 pin Socket.
Also even if you use the 2 core cable with any doubly insulated appliance, it should be protected with an earth leakage device if one is not fitted in the mains consumer unit to protect the 13amp sockets.
If the cable get damaged and there is a leakage down to earth it will detect an in balance in the live and neutral and switch off the supply.

Puzzled how you can have an lead with sockets each end. How do you plug it in?

I'd expect a standard 13 amp 3 pin plug, possibly as suggested with a dummy earth pin, at one end and if it is a B&D cable i'd expect a two pin socket at the other. see below

What sort of "sockets" does your cable have

not sure what the technical terms are but, plug one end, and receiver for a plug the other. & Its in the bin now.
