The Controversy Associated With Aluminum Wiring And Potential Repairs
In between 1965 and 1972, somewhere around 2 million houses were constructed with aluminum wiring.
The wiring that is of major concern is the single strand solid aluminum wiring, hooked up to the smaller sized branch circuits supplying receptacles, switches, lights, and appliances like dishwashers, furnaces, etc. Corrosion of the metals in the connection, particularly the aluminum wire itself, creates increased resistance to the movement of electric current and that resistance causes overheating.
Most modern homes have some aluminum wiring, including the main service wires, and the heavier 240 volt circuits that feed other major appliances, like ranges and air conditioners. The higher voltage wiring does not present the same risk as 15, 20 and 30 amp circuit wiring. what are the requirements of being a home inspector in texas
Signs of problems in aluminum wire circuitry include:
1. Cover plates on outlets or switches that are warm-to-the-touch.
2. Circuits that do not work, or work intermittently.
3. Flickering lights.
4. The smell of burning plastic at outlets, switches, or lighting.
6. Smoking outlets, switches, or lighting.
7. Tripping circuit breakers, for no perceivable reason.
Sadly, not all failing aluminum wired connections provide such easily detected warning signs, as they can fail without any previous indications or problems
How to Fix the problem?
One-- full replacement of the electrical system-- is generally much too pricey for lots of homeowners, as it can cost $ 8,000 or more. The other is to replace every single connection in each outlet, switch and junction box with a copper pigtail using a special Copalum connection-- a short piece of copper wire is bonded to the aluminum wire using a tool designed specifically for the task. The copper wire makes the connection.
But the trouble is that only electricians trained by the Copalum manufacturer, Tyco Electronics, can secure the special tool necessary for installation. So it might be hard to identify an electrician to make a Copalum repair. no title
