How Has EMP Shield Been Tested?
Isn’t a nuclear explosion required to create an EMP?
The threat of an EMP is the large amount of electricity that is induced into conductors that generate heat and can be destroyed. There are only a few testing facilities in the world capable of producing the same amount of electricity that an EMP produces.
EMP Shield has been designed to exceed the US Military requirements for protection against a high-altitude nuclear detonation that results in an electromagnetic pulse. This family of products has been tested to verify compliance with the following Military Standards:
MIL-STD-461-RS105 Transient electromagnetic pulse of up to 50 kV/m, double exponential wave with a rise time in the nanosecond range, that is applied to the equipment under test (EUT) at least 5 times. We tested at 50 kV/m and also 90 kV/m (80% above required testing voltage).
MIL-STD-188-125-1 High Altitude EMP
MIL-STD-461G Control of Electromagnetic Interference
MIL-STD-461-CS-115 The purpose of CS115 is to test an electronic or electrical system to withstand signals coupled onto the test unit’s associated cabling. The test unit will be subjected to rise and fall times, pulse width, and amplitude as specified on Figure CS115-1 at a 30 Hz rate for one minute;
MIL-STD-461-CS116 applies to 10 kHz to 100 MHz for all interconnecting cables, including power cables, and individual high side power leads;
MIL-STD-461 CS117 apples to all safety-critical equipment interconnecting cables and non-safety critical equipment with interconnecting cables/electrical interfaces that are part of or connected to equipment performing safety critical functions. The goal is to test the unit’s ability to withstand lightning transients coupled onto the test unit’s associated cables and power leads;
MIL-STD-464C Electromagnetic Environmental Effects Requirements for Systems.
Our test results show that we begin shunting the over-voltage condition in less than 1 nanosecond, and our units are designed to shunt over 100,000 Amps per phase. Our devices are scalable to any size.

How Does EMP Shield Work?
EMP Shield will protect all the electronics and equipment connected to your electrical system.
This is accomplished by shunting (shorting) the over voltage coming in from the grid and the induced voltage that is collected within your home.
Whether the source of electrons are from within your home or coming into your electrical system from outside the home (the grid), the Shield will see the surge and protect your electrical system. Our technology reacts in less than 1 billionth of a second. Since the shunting is completed incredibly fast, the over voltage is drained away from the equipment before the voltage can rise high enough to damage any equipment. We call this new technology SightSpeed™

I haven’t installed it yet but I had questions before I bought the product So I called customer service, the lady was very helpful and knowledgeable. She took my order over to phone and gave me a discount also. The product even shipped the same day.

Our house was struck by lightning on 6/14/26 and we have spent thousands of dollars replacing fried items! The electrician told me about EMP Shield and I am so confused by the fact that no one told us about this during our build. Its much less expensive than replacing so many expensive items or filling an insurance claim only to have your rates raised or get cancelled! This is my first time experiencing lightning damage and I am so grateful that a product like this exists for my families peace of mind! If I could give Aimee a 10 out of 10, I would! She was so helpful and wonderful to talk to! Everyone should have EMP Shield!!! PERIOD!

Easy to install and great service from the company
Eric Autry (verified owner) –
My EMP device sacrificed itself by absorbing a lightening strike that came in through the electric meter and power panel and I got the item replaced. Nancy made the process effortless and the new replacement device is on its way!!!

The EMP staff was very helpful and knowledgeable about their products. I am very satisfied with their answers to my questions and I felt well informed about the products that I needed after a few minutes with their sales person. I placed my order for several items and I will be a return customer!

I orginally ordered the wrong model for my type breaker panel installation but on call and all was taken care of by the company

SO APPRECIATE having a human answer the phone right away. Nancy answered all my questions and was friendly and professional. Glad to see such success from a vet-owned USA biz!

This is the best whole house surge protector I’ve ever found! My house was hit by lightning last week and with this EmP Shield circuit breaker I had no problems. My neighbors weren’t so lucky One lost her pool pump. The other neighbor lost all her electronics. My house just had two flip circuit breakers so this thing did what it was supposed to do. I am so happy I even bought an extra one should it happen again the old one comes off and a new one goes right back on.Amiee is the young woman I dealt with super nice knows her stuff and very eager to help me. I have three EmP shields one on each circuit breaker and one on my car. I will never be without them. Thank you EmP Shield I would strongly encourage everyone to have have one on their house,my sister just purchased one for hers and she was very excited and very relieved to have it. I tell everybody about it. EmP shields is the best.
