Description

ABSTRACT: This Practice provides requirements for the design and purchase of self-regulated electric heat trace systems.

This Practice describes the requirements for equipment, materials, and design services for electrical heat trace systems that use parallel-trace self-regulating type heat trace cable with ground braid. This Practice includes requirements for heat trace cable, monitor-control panel, junction boxes, and temperature sensors.

The following are not included in this Practice:
a. Series-resistance, mineral-insulated, inductance type, and impedance type heat tracing systems
b. Panelboards, circuit breakers, and field wiring of heat tracing system components
c. Installation of the equipment and materials provided
d. Insulation materials or installation
