On all power strips, the maximum power they can support is indicated on the power cable.
So the first thing to do before plugging in your electrical devices is to look at this information. Then, it’s very simple. You must add the power of each device that is plugged into the power strip.
How do I know what the power of this or that device is, will you tell me?
Well, as with the power strip, this information is written on each electrical device. I’ll give you a concrete example. Imagine that your power strip tolerates a maximum power of 3500 W. If you plug in your oven which consumes 2500 W at the same time. Your vacuum cleaner which consumes 800 W and your kettle which consumes 250 W. You exceed 3500 W (2500 + 800 + 250) = 3550 W. There is only one solution
