I have another question, as per 210.52(E)(3), Let's take a good size house with a nice big front porch that is say 1'-2' off the grade. To the left side of the house in the front yard there is a weatherproof receptacle installed as per code. Would you require another receptacle within the perimeter of the front porch?
I agree with John. The intent of article 210 is reducing the use of extension cords and this is a case where they would be stringing a cord over to the porch if they wanted to plug in a fan, TV or whatever.
I think the other side of the coin might be if the porch has steps or stairs from grade level, does the receptacle on the porch satisfy the requirement for the receptacle at the front of the dwelling accessible from grade level?
Dependent on the design of the 'front' the one on the porch may suffice for code compliance. Really could not say for sure without seeing the situation.
A situation could be what we see with holidat dec lighting, the cords all over the front of houses. That is what I refer to as 'temp lighting' & usually don't say anything about that unless it is deemed a danger.
These are just some of the questions that I get from EC's in my area. The EC's I deal with know that they can talk to me and I don't give them any bull or any attitude and I try to answer any/all questions that they will pose to me. A different EC was failed for this problem in another town, so he asked me for my opinion.
I know of one area that would not accept the one over the porch as the one for the front yard. Their take is the steps remove it from being at grade level. I could see this if the porch was out of reach above grade, but the words do support their interpretation. It just seems a little strict.
