yard light pole installation
Hello.
I'm putting up a yard light at my acreage, and I have a question about the actual installation of the light pole. I have a typical timber pole, about 35 feet long. A friend will be helping me with his bobcat to auger a 12" post hole for the pole and install the post within the hole. I have a couple of questions regarding how to hole and how to backfill it. First, how deep should I install the pole? Does it need to be at least as deep as the frost depth? I'm thinking the hole should be about 10 feet deep for my area (central Alberta, where the frost penetration depth is typically about 8'). Second, what would be the best method to backfill around the pole once it has been placed in the hole? I'm thinking there are two options - using concrete or tamping in crushed gravel. Does anyone have experience with these methods? The concrete would be a pain as we'd have to brace the pole some way until the concrete has set. I think that the local utility companies use the crushed gravel method when installing new power/phone/lighting poles. Any help is appreciated! Thanks, Corey |

A friend will be helping me with his bobcat to auger a 12" post hole for the pole and install the post within the hole. I just cut down an old telephone pole on my property. I was left with a 32 ft pole. I'm in South Carolina, and I'm using the pole in a pole barn type application, so I can't really address how far you need to sink it, other than to guess that below your frost line is probably as deep as you need to go - that's quite a few feet deep where you are. I can say, though, that I cut my pole in two, and when me and my neighbor and the front end loader were raising *that* pole it was pretty exciting. Assuming your pole is anything like my pole, it's like trying to handle a tree. My 16 ft long telephone pole was in a way different class than the 16 ft long treated 6X6's that I used in another part of the building. I've raised telephone poles over 20' singlehanded. I 'balance' them across my carry-all and flip them up while they drop into the hole. Id you get the parameters right the pole will slide into the hole. If the hole is soft-sided you might need a board to keep it from digging in as the bottom slides into the hole. My ex borrowed a friend's stake body to pick up a 25' pole. They lashed the top end of it to the top of the stakes at the cab. Used a board as you suggest, lined it up right, and it slid right in. |

Set in gravel or sand or any material contribuing to good drainage, then back fill with whatever soil was removed. Only metal posts/poles get set into concrete, and even those should have good drainage material at the bottom or they will heave. If your frost penetration is 8' than you need to go at least that depth, especially with wood. What part does the frost line play? I always thought the depts was determined by the leverage applied by the pole. What am I missing? |

I always thought the depts was determined by the leverage applied by the pole. What am I missing? If you live where the ground seriously freezes in the winter, the earth will essentially try to spit the pole out. (Look up "frost heave".) Frost heave is why in areas with rocky soil, if one picks rocks one year, there will be a new batch the next. And why in the olden days when wood fence posts for barbed wire fence were driven, farmers went around in the spring and re-drove any that had heaved. Iirc the rule-of-thumb for leverage is 1/3 the length of the pole/post for mid-range lengths; shorter more and longer less. |

You might want to check and see what your power co will put one in for. In my experience the local power companies aren't permitted to errect private poles on private property, it's a conflict of interest situation... essentially it's stealing (material and services). But often the utility workers will moonlight... their own time, their own equipment... or more likely they will recommend an electrical contractor. However, typically a phone call to the local utility company is all that's necessary to obtain the local code info for pole installation. |

If one lives where service is provided by a REC (rural electric company), they often provide/install a light for a monthly charge. One disadvantage of having my REC do it is that they won't put it on a switch; no way to turn it off. |

Neighbors who have to live the glare from the light every night will gladly assist. And continue to pay the monthly charge? Imo the better solution is (was) to have it removed. Also, what "neighbors who have to live with the glare'? This is misc.rural, not misc.burbs.g The nearest neighbor is 1/4 mile away. I can just barely see their pole light when then leaves are off the trees and I get the angle just right. Which is actually useful because when there is an outage, if their light is still on, that means the problem is in the loop over the hill and I'll probably have to wait forever for service to be restored. |

I always thought the depts was determined by the leverage applied by the pole. What am I missing? I was wondering the same thing. I had my power company put in a pole for me. I paid $135 (5 years ago). That included the pole and all the labor. That sure beat all the work and hassle, and the pole alone would have cost me around $90. There was an unused pole on my property, but they refused to remove it and reinstall it, even though I was only using it for an overhead wire to my barn, AFTER my meter. It was still worth the cost to have them do it, and I have a new pole which will last longer. I cut the old pole off and used it for corner fence posts, and when I checked the price of fence posts, I came out ahead. As far as depth, they placed the pole about 4 to 5 feet deep, and just filled with the removed soil. Ten feet is wayyyyyyy more than needed, and I dont think you will find an auger to go that deep. |
