Electric heat tracing distribution boxes are typically made from robust, corrosion-resistant polyamide or other industrial-grade materials suitable for both safe (non-hazardous) and hazardous (Zone 1 or Zone 2) areas . The enclosures are designed to withstand environmental exposure and maintain integrity even when energized . They often feature a hinged cover that allows the unit to remain intact during installation .
For hazardous areas, the boxes provide type EExe protection (increased safety) according to BS EN 50019:2000 and comply with IEC62395 for safe and industrial locations and IEC60079-30 for hazardous locations . They include main control switches to immediately shut down power in case of emergency . Ground-fault protection and alarm capabilities are standard to ensure safety during operation .
Standard entries are 20mm and 25mm ISO metric, with alternatives available such as 3/4” and 1” B.S. Conduit, Pg11, 13.5, 16, 21, 1/2” and 3/4” N.P.T., and optional 32mm entry for specialized devices . Proper creepage distances and clearances must be observed when connecting certified terminals .
Distribution boxes must conform to CSA, FM, IEEE, ATEX/IEC, UL standards, and US National and Canadian Electrical Codes . For hazardous areas, compliance with IEC/EN/IEEE 60079-30 ensures safe operation in explosive atmospheres .
Electric Heat Tracing Distribution Boxes are engineered to provide safe, reliable, and code-compliant power distribution for heat tracing systems. Key features include robust enclosures, hazardous area certification, circuit protection, temperature classification, and flexible wiring entries, making them suitable for industrial, chemical, pharmaceutical, and other high-risk environments .
