Re: temp power pole

Not gonna give the answers, but.....if you will look up your local PowerCo. online, they will probably have drawings with the answers you are looking for.

Well with an attitude like that: YOUR NOT WELCOME. Try figuring it out yourself. NOW GO AWAY

Re: temp power pole

Changed my mind...
quote from 2002 NEC.
230.26 Point of Attachment. The point of attachment of the service-drop conductors to buildings or other structure shall provide the the minimum clearances as specified in 230.24. In no case shall this point of attachment be less than 3.0 m ( 10 ft ) above finished grade.

I believe the minimum and maximum distance from the weatherhead will be governed by your PoCo.See this site for examples of poco requirements. In this case, the point of attachment is required to be a minimum of 13'-6" feet above finished grade and the weatherhead a minimum of 14'.

Re: temp power pole

I missunderstood the question. Well I thought I did. As stated, this is not in the NEC.

thanx tex.most appreciated.

Re: temp power pole

Bennie, maybe I'm still missunderstanding the question.

Re: temp power pole

Roger: I am probably misunderstanding it too.

My theory is...A minimum of 10 feet is required for the drop clearance. This means the pole must be at least 10 feet above the ground level. The dead eye will be at the topmost point of the pole.

The service head must be within 24 inches of the top, or 8 feet minimum. Does this make any sense?

now that you put it that way, yes I guess.

Re: temp power pole

Roger: I'm speculating. I never thought about this issue, actually I don't care.

The temp pole got me at first. But if a pole is considered a structure then the code section applies. I think

Re: temp power pole

Bennie,

. I never thought about this issue, actually I don't care.

boy, you and I are on the same page here.

I have asked elsewhere why an inspector would not be allowed to rule an installation safe on his own professional experience and common sense. (screw the code per wording here)

This is not the same as making rules or laws, but deeming something safe through his knowledge, education, and experience.

I see to many "it's not listed" type judgements today.

Wow, use commonsense, you know that will never fly!

Oh, is that dirt listed to hold that pole up?

Re: temp power pole

May I say that in Delaware Co. (Ohio) the electrical inspectors DO use common sense.

Not all municipalities do.

Re: temp power pole

The NESC covers most service drops and the preferred clearance over "Spaces and ways subject to pedestrians or restricted traffic only." This rule requires 12.5 feet of clearance and has a footnote which states:
Where the height of a building or other installation does not permit service drops to meet these values, the clearances may be reduced to the following:
(a) Insulated supply service drops limited to 300 V to ground 10.5
(b) Insulated drip loops of supply service drops limited to 300 V to ground 10.5
(c) Supply service drops limited to 150 V to ground and meeting Rules 230C1 or 230C3 10.0
(d) Drip loops only of supply service drops limited to 150 V to ground and meeting Rules 230C1 or 230C3 10.0

How much does your local electric utility require? We are going to 13.5 feet in order to get 12.5 feet at the lowest point of the service drop. The bottom line is that txsparky was correct the first time if he wasn't such a . . . (like I haven't been)

if he wasn't such a . .

Ouch Charlie!!!
