Help Needed — New Panel Installation With Aluminum Wiring
Hello everyone,
I recently had a new electrical panel installed at my family home and would appreciate some insight from those with experience in residential electrical work, particularly with older aluminum wiring systems.
A few concerns have come up during the project.
The home contains aluminum branch wiring, so I specifically requested AFCI protection for the 120V circuits. Initially, the electrician informed me that AFCI breakers could not be installed because the house uses multi-wire branch circuits with shared neutrals.
After doing some research on my own, I asked whether 2-pole AFCI breakers could be used instead. From my understanding, that is generally the accepted and code-compliant approach for shared-neutral circuits when configured properly. Following some discussion, the electrician agreed to revisit the issue and later confirmed that 2-pole AFCI breakers could in fact be installed.
However, I was then informed there would be an additional cost of approximately $1,079 to make the change, since it would require replacing the standard breakers with 2-pole AFCI units. What I am trying to determine is whether that additional charge is reasonable, or whether AFCI protection should have already been included within the original quoted scope, since AFCI breakers were specifically referenced from the beginning.
I have also noticed a few additional concerns during the installation:
• It appears that standard yellow wire connectors may have been used to join aluminum and copper conductors, which I understand is generally not considered compliant for AL/CU splicing applications. I already have AlumiConn connectors available and intend to request that those connections be corrected properly.
• The conduit above the panel also appears to be secured using black drywall screws. If that is the case, I am concerned those may not be the correct fasteners for long-term support and durability.
At this point, my goal is simply to resolve everything professionally and ensure the installation is safe, properly completed, and compliant with current standards.
For electricians, inspectors, or anyone familiar with aluminum branch wiring:
Are there any additional issues or red flags I should be paying attention to with this type of panel installation?
Any insight or recommendations would be greatly appreciated. 💥🔥🏠🔧🧰⚡
