Does the NCB Pro Need to Be Wired Directly into the Electrical Panel?Updated 2 months ago
The NCB Pro is designed to connect directly to your grounding conductor—either in your electrical panel or on auxiliary grounding systems—and must be installed by a licensed electrician or building biologist.
Why the NCB Pro Requires Direct Wiring
In-line device for grounding systems
The NCB Pro is meant to interrupt unwanted current and dirty electricity on grounding conductors, all while allowing fault current to trip a breaker. It must be placed in series on the grounding path for this to work effectively.
Professional Installation Is Essential
The unit must be wired in-line by a licensed electrician or certified building biologist to ensure compliance with electrical codes and safe operation.
SYB provides a detailed installation manual and offers a consulting session to support professional installation.
Installation Overview (from SYB Manual)
Identify where current is flowing on grounding conductors.
Disconnect grounding wire at panel or auxiliary point.
Insert the NCB Pro in series on that grounding conductor.
Perform electrical tests to confirm:
Dirty electricity and contact currents are eliminated.
Fault path remains intact and breakers will trip under fault conditions.
Additional Questions
Q: Can I plug the NCB Pro into a wall outlet like the NCB Plug?
A: No. The NCB Pro is an in-line wired device and cannot be plugged into outlets. It must be integrated into the grounding system directly.
Q: How long does installation take?
A: Depending on site complexity, a professional can complete wiring and safety testing in a few hours using the SYB manual.
Q: What if I have both indoor grounding and an outdoor rod?
A: You may need both an NCB Plug (for indoor outlet-based grounding) and an NCB Pro (for the auxiliary system), with proper wiring and fuse setup .
