Buying Guide: Key Considerations for Generator EMP Protection
When selecting EMP protection for generators, it’s important to examine various factors to ensure reliable and effective defense against electromagnetic threats.
Type of Protection
- Surge Protectors: Devices like T.R.A.P.- AC and Bad Wolf protectors absorb and divert high-voltage surges from lightning or EMPs, ideal for permanent installation on generators.
- Faraday Bags/Containers: Products like Xtreme Sight Line and Mission Darkness offer portable, electromagnetic shielding enclosures to isolate generators or electronics physically from EMP pulse exposure.
- Whole Home Protection: Solutions such as EMP Shield provide comprehensive defense not only to generators but entire home electrical systems.
Capacity and Size
Ensure the EMP protection device or enclosure matches your generator’s size and power rating. Faraday bags have size constraints; surge protectors must be rated for your electrical load.
Standards and Certification
Look for military certifications (e.g., MIL-STD), Department of Homeland Security listings, or other recognized testing to ensure product reliability and effectiveness during an EMP event.
Installation and Compatibility
Ease of installation and compatibility with your existing generator setup are critical. Products that plug directly into receptacles or integrate into electrical panels simplify deployment.
Durability and Environmental Resistance
Consider whether the protection device is weatherproof or waterproof, especially if your generator is stored outdoors or in harsh conditions.
Shielding Technology
Advanced shielding fabrics or multistage surge circuitry enhance protection. For Faraday bags, multi-layered metallic or diamond form linings offer superior electromagnetic shielding.
