January 9, 2026 – A critical manufacturing defect has been reported in Cerrowire CerroMax with SLiPWire 12/2 NM-B electrical cable, potentially leading to severe electrical hazards including arcing and fire. The defect, identified during a home reconstruction project, involves a hidden longitudinal slit in the neutral conductor’s insulation that exposes bare copper upon manipulation.
Product Details
Incident Overview
On December 16, 2025, during the rough-in electrical phase of a total-loss home reconstruction project, a severe manufacturing defect was discovered in Cerrowire 12/2 NM-B electrical cable, specifically from a batch made on July 30, 2025. The defect consists of a continuous longitudinal slit—a lengthwise cut—in the insulation of the neutral (white) conductor.
This critical flaw was initially latent; it was hidden beneath the outer yellow jacket of the cable and was not visible during standard installation procedures like pulling the wire. The defect’s failure mechanism became apparent when the outer jacket was stripped and the neutral wire was bent or manipulated, a common and necessary step for terminating wires within electrical boxes. At this point, the hidden slit in the insulation “popped” open, exposing the bare copper conductor. This incident highlights a significant concern for newly installed wiring where such defects might be present but remain undetected until critical manipulation or over time.
Safety Concerns
The discovery of a continuous longitudinal slit in the insulation of electrical wiring poses significant and immediate safety risks:
- Immediate Dangers: The exposure of a bare copper conductor due to insulation failure creates an immediate and severe risk of electrical arcing. Arcing can generate intense heat, easily igniting nearby combustible materials such such as wood framing, insulation, or drywall, leading to rapid fire propagation. This specific defect presents an imminent fire hazard wherever the faulty cable is installed and manipulated.
- Long-Term Risks: Since the defect is described as a “continuous longitudinal slit” along an entire 750-foot run of cable, the hazard isn’t localized but potentially systemic throughout an installation. Once walls are closed up, this exposed conductor becomes a hidden danger, making monitoring or detection nearly impossible without invasive inspection. Over time, vibration, further minor manipulations, or even contact with other conductive materials could trigger a short circuit or arc.
- Who Might Be Affected: Homeowners and occupants of homes where this specific batch of Cerrowire 12/2 NM-B cable (manufactured on or around July 30, 2025) has been installed are directly at risk of fire and electrical hazards. Electricians and contractors installing the product are also at risk during the manipulation phase, though the primary long-term risk falls on the residents.
- Property Damage Potential: Given the nature of electrical fires, the potential for property damage is catastrophic. An electrical fire originating within walls can quickly spread, potentially leading to significant structural damage or even total loss of the home, as was the case with the initial reconstruction project where the defect was found.
What Consumers Should Do
If you believe your property may be affected by this potential defect, immediate action is crucial:
- Immediate Steps: If you are aware that Cerrowire CerroMax with SLiPWire 12/2 NM-B cable manufactured around July 30, 2025, was used in your home, especially if it was part of recent construction or renovation, it is crucial to arrange for an immediate inspection by a licensed and qualified electrician.
- How to Check for Affected Product: Look for markings printed periodically along the cable jacket. Identify “Cerrowire CerroMax with SLiPWire 12/2 NM-B (Yellow Jacket) M” and specifically check for a manufacturing date of July 30, 2025, or dates very close to it.
- Prevention Measures: Do not attempt to inspect or manipulate electrical wiring yourself unless you are a qualified professional. Electrical work carries significant risks of shock, injury, or fire. If you suspect your home’s wiring may be affected, turn off the main circuit breaker if safe to do so and contact an electrician immediately.
- Reporting Procedures: Report any similar findings or concerns directly to Cerrowire and the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Providing detailed information helps authorities investigate and potentially issue wider alerts or recalls.
