Yes, the red status indicators light(s) on your SPD should be illuminated. When the red lights are ON, this indicates that your surge protector is functioning correctly and providing protection. If the light is OFF, this indicates that the unit needs service and you should contact your utility provider.

No, it's actually the opposite. Our status indicator lights do not change color - they are either on (working) or off (needs service). The red lights being ON is the normal, proper operating condition for your surge protection device.

Different Meter-Treater SPD models have varying numbers of status indicator lights depending on the design. Depending on your specific model, you may have one, two, or more red lights. These lights are typically located on the side of the unit for easy visibility.

No, our surge protection devices do not have green or other colored lights. All status indicator lights on Meter-Treater surge protection devices are red. If you're having trouble locating the lights, go to your electric meter outside your home and look for a device attached near the meter where the electric service enters your home. Check around all sides of this device for small red lights.

The most reliable way to verify your surge protection device is working is to check the red status indicator light(s) on the side of the unit. When these red lights are illuminated (ON), your SPD is functioning properly and providing protection. If the lights are OFF, the unit may need service and you should contact your utility provider. These lights are designed to be easily visible without requiring any tools or special knowledge to check their status.

Yes, the surge protector will continue to work even if circuit breakers inside your home have tripped. Our surge protection devices are typically installed at the meter-can (between the meter and the meter socket), which is upstream from your home's circuit breaker panel. This means the SPD is still protecting your electrical system at its entry point, even when circuit breakers inside your home have tripped. When you reset your circuit breakers, the protected electrical pathways will be restored. If the red status indicator light(s) on the SPD are illuminated, the unit is working correctly regardless of the state of your circuit breakers.
