the aluminum wire question

[Carl Edward Prince]

I have been doing residential work since 1983 first in Pa now in Fla.
In Pa we used aluminum #8 seu cable for 3 prong 50 amp range plugs fused at 40 amps for years .since in Fla. I have used #8 copper nm romex fused at 40 amps . I caint find it but i could swear i read a code that said nothing smaller than #8 could be used in residential wiring .I assumed it was because #8 and larger is allways Lug conected as opposed to screw connections .
did i dream this or is it a change from an older code or what? please help.

There is no current code rule preventing the use of AL in dwelling units. However I don't think anyone is selling AL smaller than 8 AWG.

You do realize that you can no longer install 3 wire range or dryer receptacles.

Bob I was PM`g you when I started to read this post and after that was my question where did the 3 wire range situation come into play.In Florida its been years since 3 wire was allowed.Think 99 cycle changed that.
