EMP Whole-House Ferrites

These custom ferrites are made of a special high-frequency material and uniquely modified to help prevent high-current saturation. A ferrite is clamped around the insulated incoming power wires in your breaker panel.Most homes require three ferrites, but a few homes may require four ferrites (see video below). Ferrite dimensions: Inner Diameter 0.72, Outer Diameter 1.5, Length 1.9.

We recommend a three-step approach to home protection.

Step 1: Install custom high-saturation ferrites over your incoming power wires. Normal ferrites will not work well due to current saturation. The ferrites sold here are each individually modified to increase their saturation levels, allowing them to suppress high-frequency energy under higher currents. Note: Most homes require three ferrites (for Line 1, Line 2, and a shared Neutral/Ground). Some homes may have four wires and therefore, would need four ferrites (Line 1, Line 2, Neutral, and Ground). Order now while in stock.

Typical installation shown below. Always consult manufacturer’s instructions, and have a professional electrician do the installation for safety. Please note that ferrites tend to make a humming or buzzing noise when high currents flow through them.

Step 2: Install a quality whole-house surge protection device. 

Step 3. Install smaller broadband ferrites around power cords of sensitive electronics.
