MµCord™

Breakthrough in Low EMF Wiring!!
Exclusively from The EMF Safety SuperStore!

At last, we are proud to offer wiring which actually reduces EMF emissions to extremely low levels. Patented design incorporates both of these EMF emission suppression features: special internal wire configuration to maximize cancellation of magnetic field emissions: 2 hot, 2 neutral, and one ground wire and shielded wrapping to completely eliminate electric field emissions!

The result is a high quality wire with the lowest possible EMF emissions (over 90% reduction compared to standard wire). Replacing existing wire with MµCord is likely to be much less costly, more effective, and probably more convenient than shielding.

See How MµCord compares to standard ROMEX® carrying 30 Amps at 120V:

Spira-Shield

SPIRA-SHIELD® FLEXIBLE CONDUIT

Need Magnetic Shielding Conduit Just For Wiring?

Spira-Shield provides high permeability magnetic shielding and physical protection for any ROMEX® electrical wiring. Made of .010" thick Magnetic Shielding Alloy. Slips over standard wiring to provide that peace of mind when it must be near electromagnetically active sources. Also reduces interference in stereo and telephone lines. Ground it for the added benefit of E-Field shielding.

Shielding performance depends on many factors, including field strength and tube diameter.
Here are some examples based on DC field, perpendicular to the THIN tube:

Field outside of tube Field inside tube
5 Gauss........................ 1 mG
1 Gauss........................ 0.2 mG
250 mG........................ less than 0.2 mG
Spira-Shield

For clarification: this item protects the cable inside the shield from magnetic fields originating outside the shield.
Thin is 3/8" ID and 1/2" OD. Wide is 3/4" ID and 7/8" OD. Priced per 10 foot length.

Thin Spira-Shield (Cat. # A275-T).....................$241.00 add to cart

1/2 inch and 1 inch ID also available as a special order. Contact us for details.



MAGNETIC SHIELDING FOIL

"Make Your Own Conduit And Save!"

Magnetic Shielding Foil

Used for years in industry to shield delicate electronic components from EMFs, this 80% nickel alloy magnetic shielding foil is now available at affordable prices for home and office use. The thinner (0.004" thick) material is easy to trim with scissors and shape by hand. Thicker material offers better shielding performance but requires snips to cut. Can be formed into magnetic barriers on cellular phones, microwave ovens, doorbell transformers, VDTs, buried wiring, and more. With snug fitting shapes, get as much as 75% attenuation of the magnetic field with one thickness. Use multiple layers for even greater reduction. Foil is available in two thicknesses and can be ordered in any length. (We recommend the use of a gaussmeter to determine the proper shape and positioning of the magnetic shield, and to confirm that the fields have been adequately reduced.)

Can be formed into cylindrical magnetic barriers around wiring to protect the shielded wire from magnetic fields originating outside the shield.

Can also be placed flat against wiring to shield an area from the magnetic fields emitted by the wire. Use multiple layers for even greater reduction.

Foil is 0.004" or 0.010" in thickness and 15" wide and can be ordered in any length. (We recommend the use of a gaussmeter to determine the proper shape and positioning of the shielding, and to confirm that the fields have been adequately reduced.)
CAUTION: Foil has sharp edges!

CONDUCTIVE TUBING

Reduces Electric Fields From Live Wires To Ground Zero!

Conductive Tubing Composed of electrically conductive black polyethylene and great for shielding electrical cords. It's easy to slide any electrical cord Conductive Tubing (even fits those giant dryer plugs!) through this 4" wide (when flat) sleeve without having to remove the plug from the end of the cord. Surface resistivity <1000 ohms/square. Only 4 mil thick, it won't hold up to tearing, heat or abuse, but it's tough enough to do a great job on the lamp cord by your bed, the air conditioner cord, or even cables in your car. Use a grounding cable, and please be careful when handling electrical cords. Specify desired length.

FERRITE SNAP BEAD

Ferrite Snap Bead "Reduce RF Noise in Wiring"

Cables can act as an antenna, especially if they pass close to a strong source of radiofrequency radiation. One study has suggested that if the cable of a hands free mic passes near the phone's antenna, it can pick up some radiation and transmit it to your ear. Our ferrite snap bead is designed to reduce RF radiation in the cable. Made in 2 halves, you simply press it around the wire at any convenient location. Couldn't be simpler. It is small and lightweight enough to be almost unnoticable, yet powerful enough (50 ohm impedence minimum) to control nasty radiation. These are brand new, top quality and will accommodate wires up to 5 mm (3/16 inch) in diameter. About 1 inch long, grey color. If you are concerned about RF radiation in wiring, this is the answer.

SOCKET TESTER
INCLUDING PROPER GROUND TEST

Check Sockets for Improper Wiring and Faulty Ground!

Socket Tester Including Proper Ground Test You know what happens when we ass-u-me? Electric sockets can be bad for a number of reasons: a wire can short or fray, a wire can become disconnected, or corrode at the contact, or the wires can be connected to the wrong contact altogether! These problems can be a fire hazard, a shock hazard, a problem for polarized appliances, and definitely a problem if you are using the socket’s ground connection to Earth your shielding.

There is no need to guess because it is so easy to test for proper wiring at a socket. Simply plug in the tester and look at the result. Large LCD display indicates if ground is missing or faulty. Easy to see LEDs light up to indicate all these possible problems:

- Voltage on ground connection
- Disconnected Ground
- Disconnected Neutral
- Disconnected Hot
- Interchanged Neutral and Hot
- Interchanged Ground and Hot
- Interchanged Ground and Hot, Neutral missing
- GFI function

This inexpensive tester can be used over and over and gives either peace of mind or a specific earning about what to do. Don’t ground to your socket without it! North American Plug only. Rated for 120V, 50/60 Hz.
