Analysis of the Change

Sections 320.30(A), 330.30(A), 334.30(A), 348.30(A), 350.30(A), 356.30(1), and 362.30(A) were revised to permit cable ties to be used for securement and support of cables, flexible conduits, and tubings. Cable ties that are Listed to UL 62275 and identified as Type 2S or Type 21S are intended to provide “securement and support” in accordance with the requirements for securement and support of cables, flexible conduits and tubings at maximum spacing intervals specified in the Code. Listing of cable ties approved for support of cables, flexible conduits and tubings are appropriate as the standard requires markings that identify critical performance ranges that can impact their suitability for use, including minimum and maximum operating temperature and resistance to ultraviolet light for outdoor installations. Cable ties identified as Type 1, Type 11, Type 2 or Type 21, without the “S” suffix for “securement and support” serve many useful wire management purposes in electrical installations, including but not limited to: bundling or routing wires for “neat and workmanlike” installations [Section 110.12]; grouping conductors in multi-wire circuits for circuit identification [Section 210.4(D)]; maintaining critical spacing in cabinets; or otherwise to provide supplemental means for routing conductors, flexible conduits or cables.
