Is un-repaired aluminum electrical wiring in a home ever "safe"? In response to inquiry by owners or buyers of homes served by aluminum electrical wiring, we receive occasional reports that some building inspectors, electricians, building code officials, industry representatives, express the view that "Aluminum wiring in your house not likely to be a real problem," or words to that effect.
Watch out: The condition and safety of aluminum electrical wiring and devices in specific individual homes cannot be reliably assured by someone who has not examined it! General "opinions" that an un-studied installation of aluminum electricial wiring is "safe" are thus nonsense.

Letter Response to Claims that Original Un-Repaired Aluminum Electrical Wiring Is Unlikely to Be a Problem
The condition of aluminum electrical wiring connections varies over an very wide range from building to building and among individual circuits and devices within specific buildings. It is possible for very unsafe conditions to be present, but not visible.
In explanation, we've attached the text portion a 2/3/94 letter from an expert on aluminum wiring, addressing this problem. The author, Dr. J. Aronstein, can be contacted at email@example.com, or contact me, Daniel Friedman. Extensive information about identifying and repairing aluminum wiring safety hazards is at ALUMINUM WIRING HAZARDS & REPAIRS.
February 3, 1994 (original addressee info) (deleted by DJF) Subject: Aluminum wiring (deleted) Dear Mr. (deleted) You requested my comments on the safety of the aluminum wiring at (deleted) and my review of the written materials provided. The question to be answered is this - are the connections to the aluminum wire at (deleted) safe? Without determining what types of connections are in the system and how they were made, nobody can answer the question. Are the receptacles back-wired or screw-terminal wired? If screw-terminal wired, how is the wire placed under the screw (straight in or wrapped around)? Are the screws steel or brass? Are the screws plated with zinc on the neutral side? What kind of splicing connectors exist in the system? If twist-on connectors ("wire nuts"), are they the live spring or restrained spring type? Did the installer abrade the aluminum wire before connecting to remove the oxide? Were the spliced wires pre-twisted together? Was a corrosion inhibitor used on all connections? Given the answers to these questions (from direct observations), an evaluation of the relative safety of the wiring system at (deleted) can be made.
