TechTopics No. 86 | TechTopics | Siemens USA

Several years ago, the National Electrical Code (NFPA 70® or NEC®) was revised to require that insulated cables for feeder circuits over 2,000 volts phase-to-ground use shielded cable construction. For decades, the code had allowed use of unshielded cables for feeder circuits. This change in the code has caused users to ask why it is that switchgear manufacturers still continue to use unshielded cables inside of the switchgear.Get price
