What is the Difference Between the NCB Pro 1 and NCB Pro 2?Updated 8 days ago
NCB Pro 1
Designed for use inside your home’s electrical panel, on grounding conductors that are protected by circuit breakers (e.g. outlets, appliances, HVAC)
For circuits with 120 V or 240 V that have overcurrent protection
NCB Pro 2
Meant for auxiliary grounding systems—like ground rods, outdoor earth stakes, or shielding setups—that are not tied to any breaker
Ideal for installations where the grounding conductor is independent of indoor electrical circuits
Quick Comparison Table
Feature | NCB Pro 1 (Circuit-Protected) | NCB Pro 2 (Auxiliary Ground Rods) |
|---|---|---|
Grounding Path | Through breaker-protected branch | Outside rods or systems not on a breaker |
Voltage & Amp Rating | 120/240 V, breaker-rated (e.g., 10 AWG or 12 AWG options) | Rated for grounding-only setup (240 V support) |
Typical Use Cases | Outlets feeding grounding mats, sheets, canopies | Outdoor rod systems, paint/ shielding applications |
Which One to Use?
Use NCB Pro 1 when you’re grounding via standard outlets in the home.
Choose NCB Pro 2 for systems tied to ground rods or external stakes, where there’s no connection to the breaker panel.
