EMP Whole-House Ferrites

From $99.00 $49.00

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″.

How to Protect your Home from an EMP or Solar CME
Please watch the video below for a more complete understanding of how to protect your home from an EMP or CME.

As you can see from the video, I 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. Recommended device: Siemens FirstSurge140 (FS140).
We don’t sell the Siemens FS140, but it is available at a number of online retailers, including:

Step 3. Install smaller broadband ferrites around power cords of sensitive electronics. We sell a number of different sizes, as well as some bundles. Please see Individual Ferrites or Bundles.

What makes the High-Saturation EMP Ferrites Special?
The short answer is that normal ferrites will quickly saturate and become ineffective when placed on high-current lines. With my knowledge of electromagnetics, I was able to come up with a unique solution to the problem. See the video below for a detailed explanation.

I believe in this method so much that I put it on my own home. Watch the video below for tips on installation of the ferrites.

For frequently asked questions, click the FAQ tab. If you can’t find the answer, please use the Contact Button to send me a note.

1. Will other ferrites work for this application? 
Normal ferrites will saturate due to the high currents flowing through the wires. The ferrites offered here are of a special material and carefully modified to increase max saturation levels.

2. Why are these ferrites special?
The ferrites are of a special high-frequency material and have been custom modified to have a higher saturation level.

3. Can I buy these modified ferrites anywhere else?
Not that I know of, no. They are modified in house.

4. Are ferrites alone enough to protect a home from an EMP or solar coronal mass ejection? 
No. A good-quality surge protection device with very high current rating is also required. In addition, it is recommended to place smaller broadband ferrites around the power cords of sensitive electronics. Standalone items could also be stored in Faraday cages (or EMP bags) when not in use.

5. How many of these ferrites will I need? 
Most homes have three large power wires (Line 1, Line 2, and a shared Ground/Neutral) coming into their breaker panel. One ferrite is placed around each of these wires, typically inside the breaker panel. Some homes may have separate Ground and Neutral wires, in which case, they would need four ferrites, one around each wire (Line 1, Line 2, Ground, and Neutral).

6. Do you make the Siemens FS140 or any other surge protection device?
No. We are not associated with Siemens. For questions regarding their product, please reach out to Siemens Customer service. Disasterpreparer LLC does not sell or warranty any surge protection device.

7. Where can I get guidance on installing a whole-house surge protection device?
The manufacturer of the SPD is the best place to get technical advice on installation. Also, it is strongly recommended that SPDs be installed by a licensed electrician.

8. Where can I get guidance on installing the EMP ferrites?
We can offer general guidance on where the ferrites should be installed, but for safety, it is strongly recommended that a licensed electrician open the panel box and install the ferrites around the power wires.
