POSP 20 is plug-on design, can be easily plugs into universal 1-inch (25.4mm) spaces load center and requires two adjacent mounting spaces (see Load Center Compatibility List below), deliver superior surge suppression performance by eliminating lead lengths.

Why Install a plug on SPD at the panel? 

• Whole Home Defense: Blocks large surges caused by lightning strikes or grid switching before they reach your branch circuits.
• Appliance Protection: Safeguards expensive, non portable equipment like refrigerators, HVAC systems, ovens, and washing machines.
• Cost Savings: Helps avoid thousands of dollars in damage to hardware.
• Installation & Maintenance Best Practices
• Keep Leads Short: keep connecting wires as short and straight as possible to reduce impedance and boost performance.
• Check the Indicators: with visible status LEDs (LED on means normal operation, off means need to be replaced).
• Maintenance: Replace the SPD if the indicator light turns off or after a major surge event.
