Conductor Sizing

[LarryFine]

If I was a computer guru, then I could add that degree symbol.

You can always just copy someone else's symbol, paste it into notepad, and save it in Documents.

Then, when you need it, open Documents, find it, copy it, and paste it where you want it.

resistance,
you don't have the character map on the laptop?

Press:
START > RUN
Type CharMap.exe into the box
Press:
ENTER

This should pop right up:

Read Line #17

If nobody minds, I am going to return the discussion to the original topic. I invite your attention to post #5 of this thread.

Ok, I'm going to open up a can of snakes---

Nice try. It is a good application of the second sentence of 110.14(C). Now go back and read the first sentence of that paragraph.

And while I am on this topic:

Mike Holt says: In general, 90 degree rated conductor ampacities cannot be used for sizing circuit conductors. However, higher insulation temperature ratings offer the opportunity of having a greater conductor ampacity for adjustment and correction purposes.

I am certain that by "a greater conductor ampacity," Mike did not mean "greater than the 75C column." Rather, I suspect that he meant "greater than you would have gotten, if you started the derating from the values in the 75C column."
