Has anybody hear of this or do this? I have heard this EC here saying when they replace panels that have AL wire running to the range/stove that they pull the range/stove out and then pull the plug or if it's hard wired and re deox (or naox or whatever you call the stuff that you put on AL wiring) and then re-tighten the connections? The EC says that the wiring will be lose in the outlet or wiring nut depend o what was used. Sure it might be a good idea, but then where do you stop?? You mind as well check the tire pressure in their cars.
 
Re: alumunin wiring

Nick preventive maintenance is never a bad thing, as aluminum wiring does tend to loosen up because it expands and contracts so much. If the wires are in good condition it is worth while to do this but just to do it on every home that's up to the EC. could be a good selling point to show you care. ;)
 
Re: alumunin wiring

I ran into just such a situation last night. A guy wants me to swap out his Federal Pacific panel, and he mentioned that there is some aluminum wiring from a remodel job that was done in the 70s. I told him I'd check all the remodeled receptacles for tightness and all the connections with anti-ox. He seemed pretty happy I'm going to do this.

I understand what you are saying, but if this job is a hundred units it going to take another 100 man hours. Do you think this is a safety issue at all?
 
Re: alumunin wiring

Yes I might even to see if possible to change out if cost will let it to cu. 1 fire behind the range could mess up any future call backs and not long reputation is bad If you are working for this E.C. be glad he is looking out for your future if you hire this E.C. be glad he is looking out for your interest.
 
Re: alumunin wiring

If I walk into a home that was built in the 1970's done in aluminum, I walk. I don't even touch it. I don't need work that bad. I will offer to completly rewire the home for some god awful price and usually get rejected. I refer them to a buddy that gives me a 5% kick for referals. :D
 
Re: alumunin wiring

We do not do work on any aluminum wiring that is used for general purpose. Typically the house would of been wired from 1968 to 1974 because of the need for copper for the vietnam war for bullets.

We totally stay away from these. As stated above, we dont need work that bad.
 
Re: alumunin wiring

Big John, there was a bit of a shortage of copper at the time and copper prices were very high (driven by supply and demand). There was talk of the price getting high enough to start melting down pennies to get the copper but the price didn't get high enough. That happened again when the Hunt brothers attempted to corner the silver market and the federal government changed to the sandwich coins. I don't think Vietnam was the problem since it had been going on since before 1963 when I enlisted in the USAF.

At the same time as the copper shortage, aluminum wire became popular but it was not of the proper alloy and we are dealing with the problems now. :D
 
Re: alumunin wiring

I know this is an old post, but it isn't a good fix just to replace the receptacles and switches with the ones made for aluminum?
 
Re: alumunin wiring

Hi, this info and more can be found if you click on "links" at Mike Holts main page. Then click on aluminum wiring. "Replace The Outlets And Switches
The other repair recommended by the industry uses switches and outlets labeled "CO/ALR". Underwriters Laboratories Inc. (UL) lists these devices especially for use with aluminum wire, although they can be used with copper or copper-clad wire. CO/ALR devices perform better with aluminum wire when installed carefully and according to best electrical practices than do the types of switches and outlets usually used in the original installations of old technology aluminum branch circuit wiring. However, CO/ALR connectors are not available for all parts of the wiring system (for example, for permanently-wired appliances and ceiling mounted light fixtures, GFCI outlets, etc). CO/ALR devices must be considered to be, at best, an incomplete repair. Further, CO/ALR wiring devices have failed in laboratory tests when connected to
aluminum wire typical of that installed in existing homes. The test conditions simulated actual use conditions; no "overstress" type of testing was used.

NOTE: If you have an aluminum wire termination in your home which exhibits symptoms of failure, twist-on connector pigtails or CO/ALR devices may be used as an emergency temporary repair for a failed aluminum termination. Should such a repair be performed, it is recommended that you arrange to have your home rewired or the COPALUM crimp connector repair performed as soon as possible.

Many homes still have the original wiring devices, and these stand a good chance of being the CU-AL type or the unmarked type. They are also getting pretty old, so that receptacles may be having trouble gripping plugs, and switches may be failing. Bending and handling of the wire should be kept to a minimum. The wire at each connection should be cleaned of oxidation, and non-flammable, anti-corrosion paste should be applied. This is not a do-it-yourself project when aluminum wire is involved.

Tighten and Check All Connections".
