Experience, knowledge, tests and research are extremely important to being able to use computers and all IT at home as smoothly and efficiently as possible. But developments do not stand still: we’ve reviewed 14 pieces of common tech knowledge to see if they are valid.
1. DO DEVICES INTERFERE WITH EACH OTHER ON POWER STRIPS?
It is often said that you should not plug this or that device into a power strip together with others. Otherwise they would ‘interfere’ with each other. This is almost always nonsense; the electromagnetic interactions are usually negligible. If a fuse is responsible for several rooms, several appliances are connected to one circuit anyway.
However, the total power of all devices on a power strip must be taken into account. Currently, this must not exceed 3,000 watts, but this is only a realistic risk for heating appliances. Coffee machine, kettle, toaster, fan heater, washing machine, and dishwasher should be plugged directly into a wall socket, and parallel operation on a multiple distributor should be avoided. PCs, monitors, televisions and IT accessories, on the other hand, are not at
