I have been reading about over loading extension leads and I have been trying to add up wattage of devices used on the one lead

Example

4 way extension lead with 13amp fuse at 250v so do we multiply 13x250 and that givesbus the total load the extension lead can take in terms of safety but in watts.

So its 3250 watts

LCD TV 150w

DVD player 12w

Nightlight lamp 40w (goes by size of bulb I think?)

Total load = 202w

Then do we do 3250 - 202 =3048watts

So the extension lead has still got 3048 of watts available for over devices and is safe as long as this number is not reached or passed (overloaded).

Is this the right way to calculate the load we have on our lead s? I think if someone could show us the right way to calculate watts load of our devices it might help myself and others (mother in law lol!) to watch that we are not overloading leads.

One other thing some devices tell you the watts that they use and some don't so how can we calculate the devices that don't so we can add these to our calculations.

Thanks
