Electrical questions, answered by experts

If your outlet is testing fine but keeps tripping, that’s a sign your GFCI outlet is working, but there’s a problem somewhere else. Try plugging in different devices and see if the outlet keeps tripping. If it’s not the appliance that’s causing the issue, it could be a problem in your wiring. Faulty wiring can be a source of electrical fires and other serious problems. We recommend arranging an inspection by an electrician if an outlet appears to be working but keeps tripping.

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

A sudden tiny spark is normal when first plugging in an appliance. However, if your plug regularly sparks, has other concerning problems, or worries you for any reason, you should call a licensed electrician to have it inspected and ensure that it is not at risk of causing an electrical fire.

You should never unplug or touch a buzzing outlet. If there are appliances plugged in that are causing the buzzing, wait until the appliance is turned off (or turn it off yourself) and then unplug it from the outlet. Test the outlet by plugging in something that won’t use much power—a small lamp works well. If the outlet still buzzes, have a pro investigate why.

Yes, you can daisy chain outlets, which involves connecting multiple outlets in series. However, ensuring the circuit can handle the additional load is important to avoid overloading and tripping the breaker. The total number of outlets on a single circuit should not exceed the recommended limit, typically eight on a 15-amp circuit. Hiring a licensed electrician is always advisable for complex installations or if you're unsure of what to do.
