Living room Surge Protector
In the bedroom we usually have a 20" iMac, printer, lamp, fan, router, and alarm clock/radio all connected to the same outlet through power strips. This is also where cellphones usually get charged. The living room has only ONE outlet, which powers the stereo/record player, two lamps, fan, dvd player, cable box, and now the Samsung [TV], plus the MacBook usually gets charged here.
What type of surge protectors should we use in these two rooms to protect our devices? What should welook for in terms of power, joules, etc?
Power surges happen when there's an unexpected spike in the voltage supplied by an electrical source. It's usually a quick event that doesn't last long, but it can fry your electronics if you're not careful enough. While you'd expect lightning strikes to be responsible for power surges, the most common ones are caused by downed power lines, short circuits, tripped circuit breakers, and a sudden change in electricity usage. This could be caused by a nearby factory or by the on/off cycle of a large appliance on the same power line, i.e. a refrigerator or a dryer.
Surge protectors and power strips with surge protection is a good way of protection your electronics against small voltage spikes. Surge protectors will divert the excess power into the ground wire. While getting a standalone surge protector, and maybe even some UPS (Uninterruptible Power Supply) for each and every outlet might be the best solution, it can get complicated and expensive quickly. If you are a home owner, you could also protect your whole home, with surge protection.
