How the NCB Plug Protects You from Surges, Grid Noise & LightningUpdated 9 days ago
The SYB NCB Plug helps reduce exposure to electrical noise, provides crucial safety during surges, and supports safer grounding when using EMF protection tools like mats and canopies. Here’s how it works—and when you might need additional protection.
What Is the NCB Plug For?
The NCB Plug was designed to safely ground EMF protection products like mats, sheets, and canopies while blocking harmful electrical noise from your home’s wiring. It also creates a safe fault path to trip a breaker if a live circuit issue occurs.
Added Safety with a GFCI Outlet
For even more safety, plug the NCB into a GFCI outlet. GFCIs trip faster and at lower thresholds than regular outlets, offering enhanced protection in the event of a fault or surge.
Protection During Lightning & Power Surges
The NCB also helps protect against everyday surges—like those from distant lightning strikes. Without it, these surges can travel through the ground connection into your EMF shielding products. The NCB blocks these surges up to a certain threshold.
However, no device can protect against a direct lightning strike. In such rare cases, all electronics (and protection tools) are likely to be damaged. Still, having an NCB may help redirect some of the energy away from your body.
What to Do During a Major Storm
During strong lightning storms, it’s best to unplug all sensitive devices.
If you’re using a grounded EMF canopy or shielded room, unplug it and leave the area.
Avoid contact with any grounded surfaces during the storm.
Why You Should Always Use the NCB
If you’re using grounding products that come in contact with your body (like mats or canopies), always pair them with the NCB Plug. It prevents harmful current from flowing through you and ensures safer, cleaner grounding.
When to Use Two NCB Devices
In more advanced setups—like when using both an outdoor ground rod and a shielded indoor room—you’ll need:
One NCB Plug for the indoor outlet
One NCB Pro for the outside auxiliary ground rod
This setup requires professional consultation to install correctly and safely.
Important Note for NCB Pro Use
When using the NCB Pro with an outdoor ground rod (which lacks a breaker), you must include an inline fuse. This fuse protects against surges that might otherwise travel along the grounding path into your body.
Additional Questions
Q: Can I use the NCB Plug without a GFCI outlet?
Yes, but using a GFCI outlet provides quicker fault detection for even greater safety.
Q: Will the NCB protect me from a direct lightning strike?
No device can fully protect against a direct strike. However, the NCB may help redirect some energy through safer paths, reducing the impact.
Q: Do I need the NCB if I’m not using any grounded EMF protection tools?
No. The NCB is specifically for use with grounding products that connect to your body.
