I was told by a technician that I need a separate surge protector for each appliance (washing machine, dryer, etc. They have electronic boards in them). I was also told that I need a special one for appliances and not the one used for electronic equipment such as computers.
Both recommendations seem wrong. A surge should be suppressed according to the power of the surge, nothing else. However, I'm not an expert and hence this question - is either (or both) of the recommendations correct?
