Richard Moore Posted March 28, 2007 Report Share Posted March 28, 2007 Found this today in a 1969 condo. Download Attachment: 070328Y009cropped.JPG 327.85 KB As far as I could tell it was #8 solid AL. They ever make that? Undersized for a 40-amp breaker (range) no matter what, no handle-tie and, oh yes, a nasty Zinsco panel. Sparky recommended, but I don't think I've ever seen solid #8 before.

Richard Moore Posted March 28, 2007 Author Report Share Posted March 28, 2007 Is answering your own post a sign of madness? Me, If you look very closely at an enlargement of the top wire it appears there are some stryations along the conductor although the end, and the wire below, do look "solid". What you (I) might have here is stranded copper #8 with field soldered ends (not the same as tinned copper), which would be OK. Best to report it as possible undersized aluminum and leave it to the electrician to determine for sure when he "evaluates" (read replaces) the panel. I'm welcome!

Bain Posted March 29, 2007 Report Share Posted March 29, 2007 I found the exact same thing this afternoon, Richard. Yes, they make #8 al, but since it has to be one size larger than copper, the #8 is only rated for 30 amps.

Richard Moore Posted March 29, 2007 Author Report Share Posted March 29, 2007 Bain, nice photo. In your case the grease is a bit of a giveaway. I can now say I've seen solid #8. Thanks. The more I looked at my photo, the more I'm convinced that they are the field tinned or soldered ends of stranded wire. Download Attachment: 070328Y009xxx.JPG 120.24 KB Even the dull color is more reminiscent of solder than aluminum. Hopefully it is Cu stranded and not Al, so at least they won't have to run new, larger wire to the range when they replace the panel. But, as I'm not certain, I've reported it as an "unknown" that needs to be investigated. I'll let Sparky scrape the conductors to find out one way or the other.

Not only did they make it, they still do. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...

Not doubting you at all Jim, but do you know where it's being used? Sure don't see it on any new residential construction around here.

Kyle Kubs Posted March 29, 2007 Report Share Posted March 29, 2007 Richard, Too late for this one I'm sure but try taking photo's of the electrical panel without a flash. You get a much clearer picture without all the light reflecting off the plastic breakers and shiny paint and such. You just have to be able to hold the camera still long enough... Sometimes there is something around you can brace you forearm against.

Go offshore or out to most of the developing world; lotta aluminum wiring out there. I think they also use it extensively in Canada, but I could be wrong. Any Canadians in here?

It's unusual for sure but I occasionally see it on new residential down here. Last one was probably about 6 months ago. Each time I see it, I snap a picture of it but then forget to file the pic away. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...

Even though copper is going through the roof at the moment, I haven't heard of any proposed move to aluminum - but ya never know that could change???
