Something seems wrong here. If that's actually happening, there's a<br>
problem with the power distribution network and you'd need a TTC power<br>
station nearby. Streetcars run on DC, not AC and those stations are<br>
used to convert 60 Hz (not 50) to DC. I suspect that power dip was<br>
caused by something else. If it was caused by streetcars, you'd see it<br>
happening frequently. A UPS is always a good idea, but I really doubt<br>
your WiFi damaged the dryer. A GFI outlet protects people against<br>
electrical leakage. It does not protect equipment. However, it's a<br>
good idea to have one for safety with outlets nears sinks etc.<br>
