Circuit Breaker Selection 
For SLT Type Cables

Notes:

1. Maximum segment length is the maximum continuous heater run with minimal voltage drop.  For breaker loading, multiple heater segments can be installed in parallel providing no individual length is longer than the maximum published segment length.  For voltages other than 240 VAC, divide full breaker amperage rating by amps/foot @ startup temperature to determine maximum total footage allowed.

2. Circuit breakers are sized per Article 426-4 of the 1999 National Electrical Code.

3. Article 426-28 of the National Electrical Code requires ground-fault equipment protection for fixed outdoor electrical deicing equipment.  Electrical connections should be made by a licensed electrician.
