remote control wall sockets ?

but also says "maximum current per socket receiver :16A"

This is simply because the innards are the same for UK and continental (Schuko) plugs. The latter are rated at 16A rather than 13A. You will see that the plug and socket part of the device are a separate part so can easily be assembled with a different configuration for the continent.

The max. 13A fuse in the plug of whatever you connect these to will protect them.

20mA @ 240v = 4.8 Watts - which is way more than most of my appliances on standby. All my TV's less than 1 Watt

Unfortunately it's not that simple. These devices are not resistive, so you cannot multiply voltage by current to get power consumption. They step down the mains with a capacitor so have a power factor a lot less than 1, i.e. they will dissipate a lot less than 4.8W.

As far as I know, all large appliances such as washing machines and dishwashers have proper mechanical mains switches so that when switched off, they will dissipate no power. Always make sure you use these switches rather than leaving devices in standby mode - although in the case of my dishwasher (which has an electromechanical timer), the only difference is the minusule power dissipation of one neon indicator. My washing machine has an LED display and computer control, and this definitely will consume considerably more power unless it is properly switched off.

Many of the most modern TVs have a low standby power consumption, but many of the older ones certainly do not.

There is of course no data giving the(leading) power factor.

I suppose the only way to check their consumption would be to connect these sockets via a Lidl/Maplin power monitor for on/off load consumption.

Can anyone help me find instructions for these sockets. mine were made by Mandolyn.
