Before we begin this post, I’d like to thank you for purchasing the Nuisance Current Blocker (NCB) plug version. Through proper use, we are confident it will bring you years of consistent results.
With that said, let’s get you started on your journey to a safer, healthier, grounding experience.

Instructions: The Basics
Using the NCB is really simple. There are just two steps to it.
Step 1) Plug the NCB into any grounded 3-prong outlet. Make sure that the prong outlet is connected to a breaker switch. This is important because the NCB is designed to maintain an effective ground-fault path.
This means if, for some horrible reason, an electrical cord is cut or something else goes wrong, and your grounding mat gets electrified, the NCB activates and sends that current back to trip the breaker immediately—protecting you.

Good! Learn the one small change you should make right now.
Tip: For better fault protection, install a GFCI (ground-fault circuit interrupter) into the outlet or up-steam in the same circuit as the NCB. Consult your electrician or a certified building biologist for more information.
Step 2) Plug the grounding mat, grounded sheets, bed canopy, or other personal grounding product (that may come in contact with your skin) into the grounding prong hole of the NCB.
Test Your NCB
You can test your NCB to see if it’s working as intended. You just need a Fluke 287 Multimeter.
Turn on your Fluke 287 and connect your grounding mat or sheet directly to the outlet. Touch your grounding mat/sheet with the black test lead, and touch the red test lead with your finger.
Check the screen on your multimeter, and you’ll notice that the current flowing through your body is higher than normal.
Now, plug your grounding product into the NCB and the NCB into your outlet. Do the same experiment, and you’ll notice that the current has either zeroed out or is very low.
Check out this video by NCB Inventor Andrew McAfee for a visual demonstration of the NCB test.
Adjust the Dial
Usually, the preset settings on the NCB are enough to stop both current and electric fields from reaching your grounding product.
But sometimes, small currents and electric fields pass through. This has to do with the electrical wiring setup in your home.
However, this isn’t a problem because you can quickly readjust the NCB to best fit your needs.
The NCB comes with a blue dial inside, which you can use to increase or decrease the resistance to incoming current. Simply remove the 4 screws on the NCB, and you can access this dial.
Check out my post, “How to Use the Resistance Dial on the NCB,” for more information. My other post, “The NCB Dial Sweet Spot,” will help you find the best position of the blue dial in your NCB. So, give them a read.
You can also watch this video by Andrew, where he demonstrates how to find the best blue dial position on your NCB.
Ensure Your Grounding Is Proper
Important Note: The NCB from SYB is designed to be used exclusively on grounding products and not appliances.
To protect yourself from hazards that stem from lacking proper grounding, be sure to evaluate that the electrical wiring in your home is properly grounded. You can do this with the help of a certified electrician.
Also, ensure that all your electrical appliances are grounded adequately to overcurrent protection devices (breaker).
Here are some videos showing examples of the difference between grounded and ungrounded appliances.

More About Your New NCB
As I already mentioned, we do not recommend using the NCB with electrical appliances. Although it’s not a hazard to plug appliances into the NCB, measurements have shown better results if you do not plug your appliances into the Nuisance Current Blocker (NCB) plug version.
To reduce harmful forces like contact current, dirty electricity, and electric fields from your appliances, ensure they’re solidly grounded to their own circuit. This creates a better path for the current, sparing your body from exposure to these forces.
And finally, although the NCB is an effective current blocker from typical household exposures, it’s not designed nor intended to solve code violations.
So, if you’re unsure about whether your electrical wiring violates the NEC (National Electrical Code), get it diagnosed by a building biologist or a certified electrician.
A Safer, Healthier Grounding Journey
You have taken the first step towards a safer, healthier home. So, congratulations. We wish you all the best on your grounding journey, and we hope this will prove beneficial to you.
