Did You Know...
Not all connectors are suitable for use with multiple nonmetallic sheath cables
March 15, 1999
 
Underwriters Laboratories (UL) listed nonmetallic sheath cable connectors are suitable for use with single cable unless specifically tested for two cable usage.
A concern with two cable usage is the fitting's ability to withstand cable pullout forces normally encountered during installation. UL subjects each cable to an individual pull test. In addition, UL investigates strap type connectors to ensure that when tightening the strap screws the strap will not pierce the nonmetallic sheath of the cable creating a possible short.
Carton shipping labels specify the type and number of nonmetallic cables for which the fitting has been UL listed. Do not exceed the manufacturers UL rating.
Always use Bridgeport's UL listed 650-DC2 NM Cable Connector or 620-NM PVC NM Cable Connector
