Okay, let's break down the situation and the code implications.

The Scenario

The new code definitively requires bushings on all conduit before pulling cable. The previous ambiguity about the requirement is gone.

The Question

Are split bushings still permitted without being considered a code violation?

The Analysis



Bushings are Required

The code states you must use a bushing. The primary purpose of a bushing is to protect the cable insulation from abrasion as it is pulled into the conduit.

Split Bushings vs. Solid Bushings

The type of bushing allowed is usually specified by standards like UL 514B (Fittings for Conduit and Outlet Boxes). The code usually refers to "approved fittings" and it is UL 514B that classifies a split bushing as a "fitting"

Do Split Bushings Meet the Intent of the Code? Yes, split bushings are designed to protect the wire insulation from abrasion at the conduit end. They achieve the primary goal of the bushing requirement. Compliance

Assuming split bushings meet the relevant standards (UL 514B or equivalent) and are properly installed, they should be considered code-compliant.

Important Considerations and Caveats



Local Amendments and Interpretations

Always check with your local electrical inspector or authority having jurisdiction (AHJ). They have the final say on code interpretations in your area. Some jurisdictions may have specific rules about the type of bushing allowed, even if the NEC doesn't explicitly forbid split bushings.

Listing and Labeling

Ensure the split bushings you use are listed and labeled by a recognized testing laboratory (e.g., UL, ETL). This indicates they have been tested and meet safety standards.

Proper Installation

Even if split bushings are generally allowed, they must be installed correctly. This usually means securely attached to the conduit end and properly seated. If a split bushing is loose, damaged, or not providing adequate protection, it could be considered a code violation.

Specific Applications

There may be specific situations where a solid bushing is preferable or even required. For example, very large conductors or certain cable types might benefit from the extra protection of a solid bushing. The code itself is unlikely to require the difference, rather the design engineer might.

Engineering Judgment

Electrical inspectors often have some latitude in interpreting the code based on their professional judgment and the specific circumstances of the installation. It's always best to have a clear and respectful discussion with the inspector if you have any doubts.

In conclusion

Assuming split bushings meet the relevant standards (UL 514B or equivalent), are listed, labeled, and properly installed, they should generally be allowed to meet the code requirement of a bushing on the conduit end. However, you must confirm this with your local electrical inspector to avoid any potential issues. When in doubt, err on the side of caution and use a solid bushing.Essentially, with this specific situation that states bushing are now required, you need to meet that minimum requirement. A split bushing would meet that requirement as they are made to protect the wires coming through the conduit.
