The power you need will be determined by several factors. A very intuitive way to know if our power is inadequate is the following:
Turn on all the appliances in your house at once. If the power does not jump, it means that surely you have a power over what you need and you have some margin to decrease it.
If the daily use of your electrical appliances frequently leads to losing power, the power you are using is too little and you will have to increase it to enjoy more comfort.
