By Euro plug you mean this?

If yes then it is described in the CEE 7/16 Regulation and for safety is limited to 2.5Ampers for Class 2 Application. So it should not exceed 550Watts.(Up to a fridge) It is unpolorised, unearthed and not fused anywhere except in the main distribution board.

Allot of EU countries are starting to use the SHUKO plug CEE 7/4 Class 1 Appplications

If you use these ones which are also unpolorised, but are earthed and fused in the plug, they are rated at 16A!  So it should handle 3500Watts!( A big heater )

Cables as it comes is fairly strict and the same 

Conductor Size Current Maximum power (Watts)

1.0 mm2 - 10 amps - Up to 2400 Watts

1.25 mm2 - 13 amps - Up to 3120 Watts

1.5 mm2 - 15 amps - Up to 3600 Watts

2.5 mm2 - 20 amps - Up to 4800 Watts

4.0 mm2 - 25 amps - Up to 6000 Watts



So like this one

In general timers start of from 2000Watt resistive load (restive meaning something like a coil heater! so they are marking the worst case scenario) If its lights, pumps etc its more slacked. You can get 3500Watt too.


So to answer your question - Yes it will be ok to hook up the fan and lighting to most plugs - because you might as well used a junction plug and it would be the same..

To be safe- if you want to add more stuff later use a 

2.5MM solid core cable

Schuko Plug- 

if you cant - just wire it directly (remove the whole plug and join it indside the plug with a wall plate)

Like this one- just let your wire come out from there and run it neatly using trunking, tacs or glue gun. Try to avoid putting plugs onto that line- like the other poster said- it is breaking regulations.. in most countries.
