  1. Surge protectors prevent all power surges: This misconception suggests that surge protectors can guard against every type of power surge, which is not accurate. Surge protectors primarily defend against voltage spikes caused by external factors, like lightning strikes or electrical grid failures. However, they do not prevent all forms of power fluctuations or issues such as brownouts, which are drops in voltage.

  2. Surge protectors eliminate all electrical issues: Some users may believe that surge protectors solve all electrical problems. In reality, surge protectors offer limited protection against specific types of surges. They cannot fix underlying wiring problems or protect against power loss due to outages or inadequate wiring conditions.

  3. All surge protectors are the same: A common misunderstanding is that every surge protector provides equal protection. In fact, surge protectors vary in quality, design, and features. Some may include cable and phone line protection, while others focus purely on electrical outlets. The level of protection also varies based on the specifications, such as Joule rating, which measures energy absorption capacity.

  4. Higher Joule ratings guarantee better protection: While a higher Joule rating indicates a surge protector can absorb more energy before failing, it does not always mean better protection for your devices. Quality and technology used to make the surge protector play a crucial role. Some lower-rated surge protectors might still offer effective internal circuitry that protects devices adequately.

  5. Surge protectors need replacement only after a surge hits: Many people think that surge protectors remain effective indefinitely. However, they do degrade over time, even without significant surges. Manufacturers often recommend replacing surge protectors every two to three years, or after significant events, to maintain reliable protection.

Clarifying these misconceptions can help users make informed choices about using surge protectors effectively.
