​Power Protection

How it works

A whole house surge protector was installed on your meter to intercept power surges. It protects appliances with motors, such as:

  • Dishwasher
  • Microwave
  • Air Conditioner
  • Washer/Dryer
  • Refrigerator

For customers currently enrolled in Power Protection, you'll continue to receive whole house protection for $6.95 per month, added to your monthly SMUD bill.

Surge Protection FAQs

What is a power surge and why do I need to be concerned about it?

A power surge is a momentary surge of excess voltage or high-energy current. It may be caused by many conditions, such as lightning, which are beyond an electric utility’s control.

Power surges can damage electrical equipment, sometimes beyond repair. Electrical appliances and sensitive electronic equipment should be protected against power surges.


How do I know if the plug-in surge protector is working?

Your plug-in surge protector has lights which show it’s working. This protector will avert minor surges with no noticeable effects. When a surge is high enough, the protector shuts off power to the plugged-in device.

If this occurs, all you need to do is reset the surge protector as shown in your owner’s manual. If you’re unable to do so, or your surge protector no longer turns on, it may be worn out.


How do I know if the whole house surge protector is working?

 Your whole house surge protector has a green LED light on the side, which is lit when the unit is functioning correctly. If the green light is off, or you hear an alarm, call us at 1-888-742-7683 to schedule a service call.


Why do I need both levels of surge protection service?

Together, these surge protectors provide the maximum protection for your electrical appliances and sensitive electronic equipment.

The Whole House Surge Protector protects “white appliances” from surges that originate from outside your home, somewhere on the electrical grid.


What are white appliances?

  • Washer/Dryer
  • Stove
  • Refrigerator
  • Freezer
  • Dishwasher
  • Garbage disposal
  • HVAC
  • Furnace
  • Well Pump
  • Hard-wired garage door opener

The Plug-In Surge Protector protects sensitive electronics from surges originating from within your home.


Will the whole house surge protector protect against low-voltage brown outs or "half power" conditions? 

No. Your Whole House Surge Protector is designed to suppress harmful spikes in voltage and current. It won’t protect against low-voltage brown outs or black outs. If you experience a brown out, please call us at 1-888-742-7683.
