You may also see hidden damage, burnt wiring, or shortened system lifespan. These issues reduce the reliability of your surge protection devices and can cause unexpected shutdowns or even fires.
Misunderstanding Device Ratings
Many people misunderstand the ratings on surge protectors. You might believe that a higher nominal discharge current rating (In/Imax) means better protection. In reality, these ratings do not always reflect real-world conditions. Some users confuse “nominal” with “normal,” thinking the tests match everyday use. This mistake can lead you to select the wrong device for your needs, reducing reliability.
Misconception | Explanation |
|---|---|
Nominal Discharge Current Rating reflects normal use | The test does not represent typical conditions. |
Higher Nominal Discharge Current Ratings mean more safety | Failures often occur due to events not covered by the In test, such as temporary overvoltages. |
Choosing the wrong type 1+2+3 surge protection device or ignoring key ratings can leave your equipment exposed. Always match the SPD type and rating to your system’s voltage and application for maximum reliability.
Believing Surge Protectors Are “Set and Forget”
You may have heard that surge protectors last forever or require no attention. This myth can put your equipment at risk. Surge protectors wear out over time as they clamp the overvoltage and divert the overcurrent to the grounding system. Each surge event reduces their ability to protect. If you never check indicator lights or replace degraded devices, you lose reliability.
Some people also believe that power strips and surge protectors are the same. In fact, only surge protection devices provide real defense against voltage spikes and induced lightning surge. Power strips simply add outlets without any protection features.
Surge protectors need regular checks for indicator lights and status windows.
Features like built-in filters and alarms help you monitor device health.
Remember, surge protection devices are not “set and forget.” You must inspect and replace them to maintain reliability.
