I guess we do some things that may seem goofy to our friends north of the border...care to share your thoughts on what?



Still alow ranges to be bonded via the neutral, main breakers in the middle of the buss and without a barrier between the main breaker section and branch. Spotty adoption. There are places not yet using the 2008 NEC.

Tables 3 and 4 (aluminum conductors) have symbols beside #10 awg, which refer us to 14-104(2). 14-104(2) doesn't mention #10 aluminum.

The likelihood of an error in a document increases by a factor equal to the importance of the document multiplied by the number of kopies.

What do you suppose the maximum overcurrent rating will be for #10 Aluminum?

When I look at the calculations, it seems there isn't much of a penalty for loading a conduit with #14 wires. But, I have to admit these calculations are dreadfully boring and it's beyond me to stay awake long enough to read all the rules. http://www.codemath.com/cgi-bin/Run.pl?script=CecAwgRw2012
