How far should power pole be from house?
Also, how close can a power pole be to a house? Maximum distance from perimeter of home to meter pole is 30′. E. ROOF CROSSING: Pole must be of sufficient height to provide 4′ of clearance over any part of the roof that GLPS conductors must cross.
What factors should be considered in determining the strength of the pole required?
The most significant factor in determining pole strength is the impact of wind on the conductors attached to the pole. Wind pressure on the conductors, especially when the conductors are loaded with ice is a significant load on a pole structure.
What is the height of 11kv pole?
7.5 M and 8.0 M Poles.
What is ground line moment?
Mg = Moment at ground-line produced by. forces acting on the pole and conductors.
How do you determine pole class?
For example, a class 1 pole has a minimum top circumference of 27 inches. If it is 25 feet long and cedar (most utility poles are cedar), the circumference measured 6 feet from the bottom must be at least 43.5 inches. The higher the class number, the skinnier the pole.

What’s the standard height for a utility pole?
The NESC released a preview of the 2020 guidelines so utilities could weigh in on proposed changes. According to the NESC, the standard height for a utility pole is 35 feet. However, that’s somewhat controversial as communication lines have been crowding out electrical supply lines for adequate space.
How tall are ground poles on electric fence?
Three grounding rods are buried within 75 feet of the charger — the Power Wizard company warns these rods should also be at least 25 feet from buildings with metal siding — and spaced 10 feet away from each other. So, you’d have a 20-foot-long row with one rod at each end and one right in the middle.
How tall should a telephone line be in relation to a pole?
Companies plan on lines sagging over time due to the effects of gravity as well as temperature, bad weather and other factors. The industry minimum for attachment points on a telephone pole is 18 feet on line lengths up to 20 feet. Longer stretches of wire experience more sag.
How big of a pole do I need for joint use?
Joint use is sharing the use of poles, by mutual agreement, between pole-owning utilities, typically the local telephone company (Incumbent Local Exchange Carrier or “ILEC”) and the electric utility. Space required is generally 1.5 – 3 feet for telephone attachments.
