Inside the NCB is a blue dial. And the purpose of this dial is to let you simulate your body’s natural resistance.
You may have already heard of our brand-new product called the NCB or Nuisance Current Blocker. It’s a one-of-a-kind product that we designed in collaboration with building biologist Andrew McAfee. You can use it to protect yourself from hazards like contact current, dirty electricity, and electric fields while grounding.
You can visit the SYB store to learn more about this product.
The blue dial is a crucial part of NCB, and you have control over how much current you want your NCB to resist.
How Does this Dial Work?
The blue dial lets you control the current flow resistance between your outlet and your grounding product.
When you use things like grounding mats and bedsheets, most of the time, the current from your outlet flows to your grounding product, exposing you to contact current.
Adding resistance stops the current immediately, letting you use your grounding products more safely. But, how much current should the NCB resist?
If you’re new to this subject, the dial is already set to maximum resistance, so you don’t have to do anything to make it work. However, if you’re an expert, you can use the blue dial to set the resistance according to your specific needs.
This is also super helpful if you’re testing the amount of current flow in the body after a specific exposure.
You can simply adjust the dial to 1000-3000 Ohms, as this number represents the resistance of the skin and body when dry. This lets you exclude human subjects from your test and still gather accurate data.
Adjusting the Dial
To expose this dial, remove the four screws and pull off the backplate.
Once you see the blue dial, you can use any standard flat-head screwdriver to start adjusting.
Turning the dial all the way to the right, clockwise, increases the resistance to about 500,000 ohms to any current flow on the green wire, the grounding conductor. Turning it all the way to the left or counter-clockwise reduces the resistance down to about 14 ohms.
Start with the dial turned all the way to the right.
The grounding conductor is connected to the grounding prong hole at the bottom of receptacle outlets.
The green wire inside your NCB is connected to the NCB grounding hole on the face (highlighted in blue) and also the grounding prong (highlighted in yellow).
The blue dial controls the resistance between these two grounding points.
