Of course, the expense depends on how much aluminum wiring is present and will vary greatly from house to house. This is where the electrician comes in. The easiest and most obvious place to find aluminum wiring is inside of the main electric panel.
The pictures below show a mix of aluminum and copper wiring inside of the panels. Just watch out for tin-coated copper wiring. This is not aluminum wiring. People do crazy things. And finally, the least reliable method but still a good one, is to read the writing on the non-metallic sheathed cable.
Specifically, look for the and gauge wires. Aluminum wiring will be marked as such. This inspection will require the inspection of at least a representative number of connections.
This means pulling outlets out of the wall, pulling switches out of the wall, taking lights down to inspect the connections, pulling wires out of junction boxes, etc. For some more detailed discussions regarding the specific hazards with aluminum wiring, here are some excellent related documents:.

What are your thoughts on this product? The short answer is that pigtailing with the Ideal 65 Twister is not a recommended repair. The Ideal 65 has been heavily promoted for that application. The connector is essentially the same as twist-on connectors that had performed poorly in previous testing, the major difference being that it is pre-filled with inhibitor compound.
Based on its construction, there is good reason to question the long-term performance of the Ideal Because of its UL listing, however, most electrical inspectors would accept this connector for pigtailing of aluminum wiring. Although the manufacturer claims that the connector has been thoroughly tested for the application, neither the manufacturer or UL have released any detailed test data.
The manufacturer states that the connector has received CSA certification for the same wire combinations. Information developed so far indicates the following: — The manufacturer did not initially claim that the connector is intended for use in the pigtailing retrofit application. Instead, the manufacturer stated to CPSC that the Ideal 65 is intended for such applications as connecting lighting fixtures and ceiling fans. CSA did not independently evaluate the Ideal 65 connector.
In fact, the use of a zinc-plated steel spring in the connector violates a CSA general requirement for connectors for aluminum wiring. Structure and Rooms. Plumbing Pipes. When It First Became Code.

While testing a receptacle, the safety officer observed arcing between the receptacle mounting strap and the screw used to connect the receptacle to the outlet box.
An adjacent bedroom light fixture intermittently flickered when this connection was made and then broke, causing a visible arc and an audible snapping sound. Circuit current was traveling through the receptacle strap and the bonding path from the screw to the box and then to the fixture and receptacles in the adjacent room.
The safety officer reviewed the hazards with the owner then de-energized the circuits and left instruction that they were not to be energized until a licensed electrical contractor has surveyed the circuits and made them safe. The safety officer will be following up to ensure the hazards have been addressed.
Most home owners have no issues with aluminum wiring, but when incorrect receptacles or conductors are installed, the threat of a hazard is possible. How does an owner find out what type of wiring is installed?
