As you can see from my post history, I am blessed with a lovely home with aluminum wiring. I am also taking steps on every project to review and mitigate the risks of aluminum wiring by using proper pigtails or Alumiconn connectors.
The authoritative references on aluminum wiring seem to have been written at least a decade ago. Have the risks from aluminum wiring been mitigated to any extent by high-efficiency fixtures and appliances becoming more common?
My thought process is that an LED fixture will generate the same light with significantly less draw. This reduced draw reduces the heating and expansion of the wiring. The expansion and contraction is what causes the separation in AL and CU/AL joins. That separation then induces the sparking that gets people hurt.
My question is entirely focused on theory rather than application. Even if modern loads actually reduce the risk, it is still imperative to use the correct connectors and strategies with AL wiring. Using proper solutions, such as crimp connectors, AFCI breakers, and proper boxing nearly eliminates the risk which is far better than any theoretical reduction.
