I was having a conversation with a friend this past Friday and this subject came up.
Does anybody have a clue as to why there is a difference in the two paragraphs?
What's the difference between "at grade level" as worded in the first paragraph and "from grade level" as worded in the second paragraph, and if there is a difference, why?
There is also some handbook commentary
NEC 2005 Handbook commentary
For one- and two-family dwellings, the phrase accessible at grade level clearly requires that the two required receptacle outlets are to be available to a person standing on the ground (at grade level). Outdoor receptacle outlets on decks, porches, and similar structures can be used to meet 210.52(E) as long as the receptacle outlet is not more than 6 1/ 2 ft above grade and can be accessed by a person standing at grade.
What does that mean?
What about receptacles installed on a ;
1. concrete patio at grade level?
2. concrete patio 8 inches above grade level?
3. deck that is 24 inches above grade level that is accessible by stairs?
Would these receptacles be accessible at grade level?
