You are absolutely correct to call that out. It's a definite hazard and a code violation.Here's a breakdown: NEC Violations



NEC 250.8 Connection of Grounding and Bonding Equipment

The grounding conductor must be connected using suitable lugs, pressure connectors, terminal bars, or other approved means. Wrapping the EGC around the cable sheathing and relying on incidental contact with a clamp is not an approved means.

NEC 314.17(C) Cables with a Single Conductor

Cables entering a box or enclosure must be properly secured to the box. The manner of attachment is not secure enough.

NEC 334.40(B) Securing and Supporting

NM cable must be secured and supported in a manner that protects the cable from physical damage. Wrapping the EGC around the sheathing and clamping it is poor support.

General Workmanship (NEC 110.12)

All electrical work must be installed in a neat and workmanlike manner. This clearly isn't.

Why It's Wrong (and Dangerous)



Unreliable Connection

The contact between the bare EGC and the metal clamp is likely to corrode over time, especially in damp or corrosive environments. This will increase resistance in the ground fault path.

Insufficient Current Carrying Capacity

The small contact area may not be able to safely carry the full fault current in the event of a short circuit. This could lead to the EGC burning open before the circuit breaker trips, creating a fire hazard and leaving metallic parts of the electrical system energized at dangerous voltages.

Strain on the Connection

Movement or vibration could loosen the connection.

Compromised Cable Sheathing

Wrapping the bare EGC tightly around the cable could damage the cable's outer jacket, potentially exposing the insulated conductors inside.

Has This Ever Been Allowed? No. This has never been an acceptable practice according to any edition of the NEC. Your Report

Your assessment is spot-on. Call it out as a safety hazard and a code violation, and recommend that a licensed electrician correct it. Be specific:

Problem

The equipment grounding conductor (EGC) for the NM cable is improperly connected. It is cut short, wrapped around the cable sheathing, and relies on contact with the metal cable clamp for grounding.

Concern

This connection is unreliable, may not have sufficient current carrying capacity to safely clear a ground fault, and is a fire hazard.*

Recommendation

A licensed electrician should properly terminate the EGC to the grounding bus bar inside the panel using an approved grounding connector or lug. The cable should be properly secured.

Unfortunately, this text-based interface doesn't directly support image uploads. However, there are a few workarounds:1.

Image Hosting Service

Upload the photo to a free image hosting site like Imgur ([https://imgur.com/](https://imgur.com/)) or Google Photos. Then, share the link to the image here. I can then view the image and give more specific feedback.2.

Describe the Image: If uploading is impossible, provide a very detailed description of the image. Be as precise as possible about the location of the wire, the type of cable, how it is wrapped, and the condition of the clamp.Good luck with your inspection! Stay safe. Flag for review
