When I worked on sites, I was often called to a customers holiday home because the Electric had tripped.
It would be fair to say probably 49/50 times the system had been overloaded.
A typical modern house will have somewhere close to 32 amps coming in to the property, However campsites and Holiday Parks are different and 10 amps to 16 amps seems to be the norm in the UK. In france I know of sites with as little as 5 Amps.
So the first thing you need to do is ask the site what amperage is supplied to the static, then time to brush the calulator down and do some sums.
Typically the voltage will be around 235 volts possibly plus or minus 5 volts which isnt worth worring about too much.
On each electrical appliance, will be its wattage in other word how much power it needs for it to work( power consumption) so lets say a kettle at 2000 watts
so the maths watts / Volts = Amps
therefore 2000 / 230 =8.69 A
My advice are things that are running permanently like a fridge freezer.work out the amperage as above, subtract that from the amount available eg 16 amps and it gives you an idea of whats left to play with.

The national caravan council recommend a minimum of 16 amps. Some parks I go on are on 32 amp great if they are the easiest way to know if they have overloaded it and a quick way is,
16 amps is 3.5 kW
A toaster 1.5 kW (1500 watts)
A kettle 2.0 kW (2000 watts)
Over
So anything on as well would trip off e.g lights, fridge

Its strange how many people cant get there head around it though Dave
One Polish family in Frejus, Iron, curling tongs, air con, (door open) fridge and hed brought is own and were complaining the electric kept tripping.
Through a polish courier explained...answer I was wrong bloke was an electrician.
mmmm

A lot of French sites now are 10 or 16 amps, Colombier is an all electric site and that was 32 Amps, problem there was hob rings shorting out when pans boiled over.

It's worth knowing that for the average domestic microwave, the 800W relates to cooking power only.
The actual steady running power could be anything 1200 to 1500W, The start up power needed anything from 1500 to 2000W.
So proceed with caution. A 2000W heater, a microwave starting up, and a few lights may well trip a 16A supply even if it seems you are well within the amperage.

Be interesting to get a definitive answer on this Firefox, I understand exactly what you are saying.
Microwaves and Air con units have an inrush current, but I am led to believe it is so quick it doesnt trip a mcb or rcd....a more technical explanation would be good anyone?

You may be right on the start up... I am not sure how long the spike lasts for, but the steady operating wattage is definitely at least 1.5x the rated wattage.
On a supply it may not be critical but running off an inverter or Genny it is usually significant.
