Top articles this week covered topics including NFPA 20, hydronic heating systems and medium-voltage distribution systems.

1. Best practices: Ensuring NFPA 20 compliance with diesel-driven fire pumps
To meet NFPA 20, existing buildings must upgrade fire pumps. Learn how
2. Hydronic heating systems: How can you save by lowering the water temperature?
Lowering the temperature of heating hot water systems is a key step toward decreasing energy used to heat buildings, and toward decarbonization and electrification
3. Back to basics: How to design medium-voltage distribution systems
When designing a medium-voltage electrical distribution system, the end user’s safety, system reliability and equipment maintainability are key components for the designer to consider.
4. Back to basics: Sizing low-voltage power conductors for a lift station
Electrical engineers must learn to size electrical conductors appropriately per the NEC
5. How to prevent shock and arc flash hazards in electrical systems
This article serves as a guide to understanding electrical hazards and establishing electrically safe work environments
