for immediate release

Florida, NY – Remee Wire & Cable, a leading manufacturer of electronic wire and cable, announced their line of PowerPipe™ Class 4 Fault-Managed Power (FMP) Cables, part of their Activate™ family of Powered Cable Solutions, now meets the new UL 1400-2 standard for Class 4 Fault-Managed Power systems and are rated CL4P. These cables have passed a rigorous series of UL tests at ETL Labs (part of Intertek’s global lab network) to be certified to UL-1400-2 and ensure they conform to the safety and performance requirements as required by UL 1400-2, a recent update to the National Electric Code (NEC).  Remee is one of the first wire and cable manufacturers to have their Class 4 FMP cables certified to UL 1400-2.

ETL describes the CL4P listing as a Class 4 jacketed cable for use in plenum applications (air handling spaces), riser applications, in buildings, and fault managed power systems.

These CL4P rated Class 4 Power Cables feature multipair copper conductors in 18, 16 and 14 AWG, unshielded, with Remguard™ insulation and jacket.  They can be partnered with the REMFO™ line of tight buffer or MicroTube (loose tube) fiber optic cables for hybrid configurations, tailored to deliver Class 4 power and enhanced data at extended distances.

Remee’s Activate™ PowerPipe™ cables are a cost-effective and resilient power cabling solution for distributed electronics that meet the new NEC Class 4 standard for fault-managed power systems. This technology allows for controlled power distribution that is safe, less expensive, faster to install, and supports growing digital power technologies such as Digital Electricity* (DE) and those required in smart buildings.

PowerPipe™ cables are used with DE* to support a large variety of applications, such as:

  • DAS
  • DRAN
  • Small cells
  • PoE
  • LED lighting systems
  • Security cameras
  • Passive Optical Networks (PONs)
  • ODAS
  • Data Centers
  • Wireless Access Points (WAPs)
  • BAS
  • Rooftop macro cells
  • Intelligent building
  • Indoor agriculture
  • IoT sensors


About 2023 NEC Edition NFPA 70

The new articles in this edition cover specifications of instrumentation tray cables used to connect alternative energy systems to utility service equipment, as well as Class 4 fault-managed power systems and cables. Class 4 is a new standard for fault-managed power systems, which includes packet energy transfer (PET), Digital Electricity* (DE) and other smart transfer systems, as it was not covered in Classes 2 or 3.


About Class 4 Fault-Managed Power Systems

The power systems covered under Class 4 utilize low voltage power for safety and ease of installation.  Yet, these systems can transmit nearly 20 times the power of PoE systems, which are limited to 100W, and run over hundreds of meters. Therefore, Class 4 systems can utilize a single cable run for both data and power.

In addition, these types of power systems limit the energy and power available during a fault event.  For example, if a person were to touch an exposed wire, the system would immediately shut off before any harm is caused. The advantages of Class 4 systems include:

  1. Safety – with low voltage and fault-managed shut-off features.
  2. Efficiency – requires only a single cable pull, resulting in a lower cost of installation.

UL 1400-2 was published to outline requirements for the safe installation and operation of Class 4 cables, including cables for DE*.
