Do whole house surge protectors protect ungrounded outlets?

How do you make an ungrounded outlet safe?

You can fix ungrounded outlets by rewiring the electrical circuit or installing GFCI protection at the outlet or circuit breaker. Rewiring is the only option that will ground the outlet safely.

Does a GFCI outlet protect against surges?

A GFCI protects from ground faults (such as an electrical short), whereas a surge protector protects against surges (such as a lightning strike or a power outage). You can buy a surge protector with built-in GFCI protection. In fact, all of my surge protectors have built-in GFCI and a test and reset button.

Can an ungrounded outlet damage electronics?
