Point of use Surge Protection Devices (SPD) are low impedance circuits designed to clip transient over-voltage that can damage sensitive AC loads. Most electrical products can easily withstand over-voltages up to 700 volts. SPD’s are sacrificial devices that will operate for many years without requiring replacement. However, SPD’s are not immune to electrical faults. They will fail during ground fault conditions. The longer your electrical system takes to clear a fault, the more apt your electronics are to be damaged. Better designed SPD’s will fail open during ground faults and hopefully protect your electronics. For this reason, having the ability being to replace or remove the SPD from the circuit is more desirable than having the SPD enjoined with the AC receptacle. Things to remember about severe electrical conditions are: High voltage transients and circuit faults are more common than you realize. The best surge devices are listed to UL 1449 3rd Edition. Surge protectors like fault protection are only as good as your electrical grounding.

Can a surge protector be mounted in a non-metallic box? Sure. You will note that photo #2 of this article shows that very installation.

Can I install a surge protection receptacle into an existing box that is plastic? Or do i need to replace the box with metal? I noticed that the receptacles at Home Depot come only with metal boxes.
