Why Are LED Indicator Light of Surge Protectors Red in Color?

Most surge protectors typically use red and green as LED lights to indicate the active status of certain functions. The red color LED light that is on typically means that the surge protection device is in active protection mode and all connected devices are safe from power surges.

Green color LED light is used for displaying the grounding status of the A/C line. When the green light is on, it means there is no problem with the grounding of the AC power line.

Surge Suppressor Basic Questions

Whenever you are unsure what the LED indication lights mean, it is always recommended to read the owner’s manual and check what each LED indication light means. Alternatively, you may also want to call the support hotline of the manufacturer and get a quick and easy answer.

Never assume things.

Flickering red LED indication light could mean different things altogether. If the red color LED light of your surge protector is not lighted up, it most likely means that your surge protector is dead. It may have exhausted its capability to perform surge protection.

Always refer to the instruction manual or call the support hotline for confirmation.

How Often Do We Need to Replace Surge Protectors?

There is no standard answer to this question. It all depends on the number of hits (power spikes absorption) your surge protection unit has gotten over a period of time.

A surge protector lifespan largely depends on how many joules the surge protection device has. By and large, the more joules a surge protector has, the more “hit” it will be able to withstand. Typically a surge protector will no longer be in active protection mode when the joules are used up. As such, the red color LED indicator light will no longer be on. To be 100% sure, always check with the manufacturer’s customer support.

As a good rule of thumb, any surge protectors that have been around for more than 2 years should be replaced with a new one that comes with better surge protection capabilities.

It is always our recommendation to add on whole house surge protectors as the first line of defense against catastrophic power surges.

How to Stop Surge Protector from Beeping?

Most of the time, when your surge protection device is beeping, it is most likely warning you about something bad. Read up the owner manual and see what the beeping means.

Turning off the power to the surge protection will definitely stop the beeping but it will not solve the issue that it is trying to warn you about.

Again, if in doubt, always pick up the phone and give the customer service a ring.

Helpful Tips: Have the manufacturer’s hotline number written down on a label and stick it to the surge protection device for convenience.

How to Tell if the Surge Protector is Broken?

The most indicative sign is when there are totally no active LED indicator lights coming from the surge protection unit, even after you properly reset your surge protection unit. When the red LED indicator light of your surge protection device is no longer lighted up, it usually means that your surge suppressing hero is dead and it’s time to get a new one.

Another telltale sign could be the continuous flickering of the Red LED lighting on the unit. The fact that it is flickering could mean that it has gotten hit recently or it is warning you that it is no longer able to protector all connected devices against power surges.

Do not confuse Red LED light that is on with the flickering ones. If the red LED is on, it usually means the surge suppression unit is in active protection of all your plugged devices.

An audible alarm is yet another clear indication that your surge protection hero is no longer capable of protecting your electrical kingdom at home.

Be sure to always check the manufacturer manual to be 100% sure.

Will Surge Protector Stop Breakers from Tripping During Power Surges?

The short answer is NO.

Circuit breaker trips whenever there is a circuit overload – an excessive amount of electrical current caused by a short circuit, current overload, or even ground fault surges. Circuit breaker trips so as to prevent severe damage to electrical wiring belonging to electrical devices which may cause potential fire hazards.

A power surge or transient will not trip a circuit breaker but it will cause direct damage to the electrical device or appliance if a surge protection device is not present. Always get a reliable surge protector to protect your plugged devices from electrical transients or power spikes.

The key difference between a circuit breaker and a surge protector is that a breaker has the capability to interrupt excess current flow whenever a faulty condition occurs. A surge protector is only able to take the “hit” (absorb the electrical current) from power spikes.
