A transient surge protector and a surge protector are essentially the same thing, with the terms often used interchangeably12. Both devices are designed to protect electrical devices from voltage spikes in alternating current (AC) circuits12. The main difference between the two is that a transient surge protector is specifically designed to limit the voltage supplied to an electric device by either blocking or shorting current to reduce the voltage below a safe threshold1. On the other hand, a surge protector is a device that diverts any extra voltage to the ground, preventing it from reaching the connected devices2.
Another difference between the two is that a transient surge protector is typically used in commercial facilities to protect electrical systems from lightning strikes, grid switches, and system faults1. In contrast, a surge protector is commonly used in residential settings to protect electronic devices from power surges caused by lightning, switching of electrical loads, or other internal and external factors2. It is important to note that not all power strips are surge protectors, and a power strip that is not designed to protect against power surges should not be relied upon for protection during power surges3.
