Class 4 Fault-Managed Power Systems (FMPS) enable the safe delivery of up to 3.2 kW per conductor pair through continuous real-time monitoring and rapid fault isolation, providing a high-efficiency alternative to AC and 48V DC for telecom and edge-infrastructure applications. This session reviews an example implementation of the safety architecture defined in UL 1400-1, NEC 726, and emerging Canadian standards, including the CSA development of FMPS equipment requirements (C22.2 No. 0.24), FMPS cable requirements (C22.2 No. 356), and proposed integration of Class 4 into Section 16 of the 2027 Canadian Electrical Code. A hands-on demonstration will show an example of Class 4 system behavior under fault conditions at 3 kW per conductor pair
