scope:

This standard applies to general, testing, marking, and documentation requirements for skin effect trace heating systems rated up to and including 5 kVac and 260 °C maximum skin effect insulated conductor temperature. These heating systems are intended for installation in accordance with the CSA C22.1, Canadian Electrical Code, Part I (CE Code); NFPA 70, National Electrical Code® (NEC®) in the USA; or with any other national electrical installation code, as applicable.1

This standard applies to skin effect trace heating systems intended to be installed in ordinary and hazardous locations. The hazardous locations include the following:

1National Electrical Code and NEC are both registered trademarks of the National Fire Protection Association, Inc.

This standard also applies to termination assemblies and control methods used with skin effect trace heating systems.

NOTE 1-Requirements for certification at voltages above 5 kVac or skin effect insulated conductor insulation temperatures above 260 °C may be considered under a special investigation by an accredited certification body.

NOTE 2-Information on transformer, power distribution, and controls components can be found in IEEE Std 844.2/CSA C293.2.2

Purpose

This standard provides testing, marking, design, and documentation requirements for skin effect trace heating systems. Skin effect heating systems are intended to

a) Maintain design temperature; and

b) Provide electrical, thermal, and mechanical durability and reliability
