The Installation Instructions for the AlumiConn™ include using copper pigtailing and an AlumiConn connector for the solid conductor aluminum ground wire, handling it just the same as the aluminum hot and neutral wires.įor the specific case shown at left (connection of a ceiling fan), King Innovations points out that. That is why modern codes require full-size ground conductors. The probability of any wire termination or splice of a ground conductor actually carrying substantial current is low relative to the circuit conductors (line and neutral), but not low enough that it can be ignored. The electrical ground is part of the electrical safety system and must be capable of carrying current under various fault and malfunction conditions. Jess Aronstein for clarifying this question with the comments below. Our photo (left) shows an improper aluminum wiring repair - the white twist-on connector is not recommended for this application. Readers repairing aluminum wiring and faced with limited space in the electrical boxes of an aluminum-wired building ask if it is acceptable to just pigtail the current carrying conductors - the "hot" and "neutral" wires, leaving the aluminum ground wire alone. ![]() Do We Need to Pigtail the Ground Wire When Reducing the Hazard of Aluminum Electrical Wiring? We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. This article series describes the acceptable methods to repair aluminum wiring, including which aluminum wire connectors to use for safest results. This article describes the importance of including repair of the grounding conductor (ground wire) in buildings where where solid conductor aluminum electrical wiring is being repaired. ![]() We have no relationship with advertisers, products, or services discussed at this website. A lug system whose lugs are, amusingly, made of aluminum.InspectAPedia tolerates no conflicts of interest. ![]() Certainly the most likely place for installs to deviate from spec (especially homeowner installs) is torque.ĬPSC is correct that not every connection type is available in CO-ALR. But all they say on the matter is "in real world conditions", which sounds to me like admission that they do work in spec conditions. Certainly it would be more persuasive if they could point to some rate of house fires from CO-ALR failures. Regardless, NEC permits CO-ALR, so clearly the NFPA agrees (that's National Fire Prevention Association).Īll we have against them is CPSC's opinion, since they have not provided any provenance to whatever testing they have done if any. NEC 2017 requires use of a torque screwdriver, so to complete the compliance, set torques correctly. UL's testing presumes the end user will follow the instructions. They listed these items as safe for use in that modality, as captured in the product's labeling and instructions, which are part of the listing. That's not my opinion, it's Underwriter's Laboratories. ![]() If your goal is compliance with a gold standard so you are lawsuit-proof, then CO-ALR receptacles will suffice. The main failure mode of aluminum wire is arcing as a result of corrosion, and that's what AFCI breakers detect. If your goal is safety, install AFCI breakers.
