Both devices are cutting-edge Nuisance Current Blockers (NCB), designed to make body grounding safer during the use of grounding mats, sheets, or EMF canopies. Here’s how they differ:

1. Installation & Coverage

• NCB Plug

  • Plugs directly into a wall outlet.

  • You then plug your grounding product into it.

  • Designed for single-outlet use—perfect for individual grounding items like one mat or sheet.

• NCB Pro

  • Installed professionally into your home’s grounding circuit — typically at the main breaker panel or a central grounding point.

  • Provides whole-circuit protection, securing multiple outlets and grounding paths at once.

2. Electromagnetic Protection

Both offer robust protection by using internal resistors that isolate harmful currents:

• Both NCB Plug and Pro:

  • Eliminate contact current

  • Filter dirty electricity (high-frequency transients)

  • Reduce electric field EMF

  • Maintain a safe ground-fault path for safety  

• NCB Pro takes it further by also:

  • Eliminating unwanted magnetic fields from the entire grounding circuit — a deeper layer of EMF protection.

3. Use Case & Availability

• NCB Plug

  • Excellent for targeted personal use (e.g., one grounding mat or canopy).

  • Plug-and-play: no electrician needed.

  • Available only in USA and Canada.

• NCB Pro

  • Ideal for whole-home or multi-outlet grounding setups (e.g., canopy plus mats in multiple rooms).

  • Requires professional installation.

  • Suitable for international use and larger installations.

Comparison at a Glance

Which One Should You Choose?

• NCB Plug → Best for basic, personal setups using relative few grounding devices.

• NCB Pro → Ideal when you want full-home grounding protection, or if your installation uses multiple grounding components across rooms.
