Never daisy-chain power strips to other power strips or extension cords Never allow a power strip to be exposed to a moist environment Avoid running too many high-energy consuming appliances through a single surge protector at once High-energy consuming electronics/appliances include window AC units, space heaters, refrigerators, washers/dryers etc. Only one power strip should be plugged into a single two-outlet electrical socket Never cover a surge protector with carpet, furniture, or anything that would limit or prevent air circulation IMPORTANT: The protective components inside surge protectors that absorb over-voltage spikes will eventually wear out. Most estimates put the average lifespan of a surge protector from 3 to 5 years
