1 kw is about 4 amps, 2 kw is about 8 amps so work it from there. Most sites are 10 or 16 amps. Remember to allow for things such as the fride etc...

That's a nice, simple formula to work it out, I was wondering about that myself, cheers Zaccy!

You really don't need to worry about the TV or fridge as they only use a little, but a microwave can be 500-800 watts depending on the size, so you should not use it along with a heater, or kettle, or hairdryer or similar. Anything that "heats" always uses a lot and should be used with caution. Most sites will be OK with a 2 kw heater if used alone.

All electrical appliances will have a plate on the back that tells you the wattage.

The things you need to look out for are anything that heats -kettle, heater, water heater, hairdryer, iron.

Thing to remember re microwave is the staed 800w is the HEATINg power, not usage power.As a rough guide double it and take 10% off to get usage power

so,

800w microwave - 800 * 2 = 1600 - 10% = abou 1440 ish watts , or 6 apms

From what I remember at school ( too many years ago...) you divide the power by the AC voltage to get the current - eg 2000W divided by 240V equals 8.3Amps.
