What is a Surge Protective Device? SPDs are designed to limit over-voltage to protect devices that could be damaged. Normal household voltage is 240 volts AC. In an AC circuit, a voltage spike is a quick event, typically lasting 1 to 30 microseconds that may reach over 1,000 volts. Lightning hitting a power line can cause a spike of thousands of volts. A motor, when switched off, can generate a spike of hundreds of volts. Spikes can also occur on telephone and data lines
