ALUMICONN SERIES

To avoid clutter we didn't color the hot and neutral wires, but the same procedure as described above would apply to those elements of the circuit as well.

An aluminum ground wire headed for power-out to the next receptacle box in a chain.

If instead we were wiring a device, say an electrical receptacle, in our OPINION preferably wire #2 would be a copper pigtail wire connecting from the AlumiConn to the ground connection screw on the receptacle and, if it's a metal junction box, onwards to connect to the box as well, using an approved ground connector such as screws sold for that purpose.

A copper wire that in the illustration is a ground coming out of the fan assembly, is connected directly to the terminal block.

An aluminum ground wire entering the receptacle box,.Notice that we show two solid aluminum (silver colored) and one solid copper (copper colored ) ground wires leaving the connector. In our version of the AlumiConn™ wiring sketch (left) the incoming solid aluminum ground wire is visible in silver connected to the top terminal in the AlumiConn™ connector - any terminal on the AlumiConn can be used to receive either an aluminum or a copper wire. Using the AlumiConn for aluminum ground wire repairs However, if the installer is wiring a device such as an electrical switch or receptacle (a more common situation), pigtails would be needed. in the application shown the use of "pigtails" is not required.The aluminum wires and fan can be directly wired to the AlumiConn connector. 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.
