2 #8 conductors with #10 ground

The heat pump installer used NM cable I had not seen before: the 3 condutors were #8 but the ground was #10.

Is this OK? Just a move to shave a little cost off?

Also - what is the max amperage #8 can carry?

Thanks!

It's perfectly normal and commonly done. In a perfect world it will never carry any appreage. It is only there to protect in a catastrophic failure.

Is this what they used http://i37.photobucket.com/albums/e8...Elect_Whip.jpg ? If so that's normal. If they used like Romex I don't like it and some code wont allow it.

That's strange. It still works for me but Furds is an acceptable whip also.
