Buried Electrical Wiring in Yard
Our new-to-us home has a garden and koi pond at the back of the
property. The pond uses a submersible pump and, in winter, a heater to melt hole in ice. Switch for the present wiring is in garage, which (I'm guessing) is about 70 feet from the pond. The wire/cable is white, like two round sections with a flat white section between them. Outlet (yikes!!) is an outdoorsy looking thing with a metal back and a plastic cover....it is not fastened to anything for support, just basking on some rock near the pump/filter. No GFCI. Yike again. I would like, eventually (fairly soon, like by next spring), install underground lines for water and for electricity for use at the pond and the garden. There is a septic field between the house and garden, so that is (I think) a consideration. When I had a chandelier installed by an electrician, I asked him about installing underground electric, and he told me it must be 4' down....I haven't found anything online today that addresses that....several articles that recommend burying line 12-18", using conduit, RF line, etc. We had an electric line changed from 220 to 120 when we installed gas range, so need to re-study what breakers control what in the house, as those marked on the breaker box may be wrong. Indiana doesn't require electricians be licensed.... The garage wiring (and pond) may be on the same circuit as kitchen. Have yet to blow a breaker. Questions: How deep are gas and electric lines (from utility) buried..we had 811 mark them, but no idea of the depth. When we had cable installed (TV and internet), the guy ran a little thing that put the cable barely into the sod (and cut my puny little 1/4" water line to the pond). Is cable supposed to be a minimum depth? The cable layout really screwed my plans for planting shrub and flower beds. |

There are devices that put a hiogh-frequency signal onto power lines and a matching detector to trace the general direction/routing of the wire. Find an electrician friend who has one of these and use it to mark the route of the present line. When you find the route, mark it with paint and then take a number of photos so you have a record. You can run the new line in over the septic fiekd drain lines, most drain line are more than 12" below the surface. Also, do your digging with a manual shovel, not some neighbor with a front loader who will just dig up whatever is inthe ground. ANd, since the load on the power line is faily small, you can use more wire and route the lines away from wherever you think you might be digging in the futue. Just document with photos where everything is. We had some work done here 45+ years ago and I have some 45+ year-old photos of the work that still come in handy every few years. |

In that case and if there is no inspection, I'd just do basically like the cable guy and put it deep enough to not be going to get it w/ the casual digging of an annual bulb planting and the like but not worry about real depth as there's little reason to be digging in turf areas. And, of course, as another respondent noted; make drawings of where stuff is. Running it in conduit is certainly a way to add some comfort, obviously. -- |

Check to see how it was done. It does sort of sound like a hack job, but maybe you got lucky. |

An energy auditer is there to look at energy issues, not to make sure your property is up to electrical code, about which they aren't expected to have any knowledge.

An electric utility wire buried only a foot deep is another and clearly a major code violation. At least here in the USA |

Periodically, he'd take them out, wash out the top, dirty ones and reorder them in the stack (they were in a steel barrel). -- dadiOH ____________________________ Winters getting colder?

When we had cable installed (TV and internet), the guy ran a little thing that put the cable barely into the sod (and cut my puny little 1/4" water line to the pond). Is cable supposed to be a minimum depth? Deep enough the lawn mower won't cut it. When I had cable, it too was put in like yours. I forget the tool used, a vibrator or something. Maybe a tickler. I'm sure you can rent one. In your other post I see you want to use a tiller, So maybe just pull up the cable, disconnect it from your house, and run it where you want it, away from the beds, next to the wall or something. Buy a length of outdoor co-axial cable, connect it with a female-female connector, wrap it in the silicon tape referred to bellow, bury it all, and then connect back to the house. Or maybe call the cable company and say you want to use a tiller, didnt' realize this when they were there, and how much woudl they charge to come out and do it again. Who knows, maybe they'll do it for free. The cable layout really screwed my plans for planting shrub and flower beds. Don't let it do that. TV cable is not something special, like if you dug and uncovered the CERN Collider. The voltage is tiny, for one thing. You can put your hand on the center lead and the ground and you won't feel a thing. The installer may have left a foot of slack in the box on your wall where the cable came out of the ground, but even if he didn't, it will only take a tiny bit of extra length to dig a little trench below the cable and and let it lie a few inches lower where you want to plant flowers. Or better yet, you can just plant your flowers and shrubs around the cable. The flower and shrub roots will not hurt it (they'll just detour when the reach something that's not dirt, like they do when they reach the side of a sidewalk or the foundation wall of the house) and if perchance after 30 years a problem ariises, I think the cable company will repair it for free and won't ask which came first, the shrubs or the cable. You can even cut the cable and put your own F connectors on the cut ends (You can borrow a crimping tool or buy a cheap one. It comes in handy. The self-screw (don't need crimping) F-connectors have never worked for me.) , then put 3 or 6 feet of extra cable, and wrap the whole thing with silicon tape. There are other names for this, but it's tape you stretch to 3 times its length when putting on, and it pulls back, making a very tight connection. Wrap it around 2 or 3 times and within a few days, it merges into one waterproof blob that you can bury. In my experience the tape comes wrapped on a white plastic spool, instead of a cardboard one. My cable inslaller left a foot in the box and he folded it tightly, which he shoudlnt' have. Sharp bends tend to make signal rebound locations which can put ghosts in the tv image. But his didn't so maybe he knows more about it than I do**. Still, when you bury the extra 3 feet, let the cable spread out instead of bending or wrapping it tightly. The cable doesn't have to go in a straight line. **Or maybe he didn't. I wanted the cable box in the closet, 5 feet from the tv, instead of where I could see it. The cable itself came in through the closet so it was no more work for him, but he said he wasn't sure the cable signal out of the box could go the extra 5 feet. He seemed sincere and he did it for me so he had no reason to lie. Later when I was running more cable through the basement ceiling, I had the cable running 3 times the length of the house, about 120 feet, and it worked fine. If necessary, more questions can be asked at sci.electronics.repair. |

I would suggest using UF type wire AND putting it in some
PVC pipe, probably 3/4 dia, so that if you should dig into it while planting a shrub someday, you will hit the PVC and avoid nicking the UF wire, regardless of the depth.... You don't have to make joints and connectors with the PVC since it is being used only as an open conduit and that makes it cheap and easy. The UF will be resistand to anything that is going to happen... Just a suggestion, which works well for me, who is always digging around with a shovel somewhere.... |

I would like, eventually (fairly soon, like by next spring), install underground lines for water and for electricity for use at the pond and the garden. *There is a septic field between the house and garden, so that is (I think) a consideration. *When I had a chandelier installed by an electrician, I asked him about installing underground electric, and he told me it must be 4' down....I haven't found anything online today that addresses that....several articles that recommend burying line 12-18", using conduit, RF line, etc. We had an electric line changed from 220 to 120 when we installed gas range, so need to re-study what breakers control what in the house, as those marked on the breaker box may be wrong. *Indiana doesn't require electricians be licensed.... *The garage wiring (and pond) may be on the same circuit as kitchen. *Have yet to blow a breaker. Questions: *How deep are gas and electric lines (from utility) buried..we had 811 mark them, but no idea of the depth. *When we had cable installed (TV and internet), the guy ran a little thing that put the cable barely into the sod (and cut my puny little 1/4" water line to the pond). *Is cable supposed to be a minimum depth? Deep enough the lawn mower won't cut it. * When I had cable, it too was put in like yours. *I forget the tool used, a vibrator or something. * Maybe a tickler. *I'm sure you can rent one. Per NEC, the cable to the pond needs to be minimum of 12" deep. It's an energized 120V circuit, not cable TV. *In your other post I see you want to use a tiller, * So maybe just pull up the cable, disconnect it from your house, and run it where you want it, away from the beds, next to the wall or something. *Buy a length of outdoor co-axial cable, connect it with a female-female connector, wrap it in the silicon tape referred to bellow, bury it all, and then connect back to the house. It's a circuit for a pond pump, not cable TV. |

Our new-to-us home has a garden and koi pond at the back of the property. *The pond uses a submersible pump and, in winter, a heater to melt hole in ice. *Switch for the present wiring is in garage, which (I'm guessing) is about 70 feet from the pond. *The wire/cable is white, like two round sections with a flat white section between them. *Outlet (yikes!!) is an outdoorsy looking thing with a metal back and a plastic cover....it is not fastened to anything for support, just basking on some rock near the pump/filter. *No GFCI. *Yike again.

Here in Arizona, we recently installed code approved underground cable to a well head. Cost of $5,000 [cheap] to go about 150 feet. including wiring and metering connection to APS utilities. The ditch required minimum depth [can't remember] and this caught me off guard, minimum width! [also can't remember] But it took some guy with a major piece of equipment to dig the trench for over half a day. Plus, WE chiseled out the solid boulders hit here and there. Just to meet the depth/width reuqirements. However, the wiring looked like standard underground cable you can buy at HD. That 10 Gauge two conductor stuff with GND. You're not attaching directly to the AC Utilities, so you should be able to do your own. Put in proper GFCI breaker setup, get a trencher, dig the minimum depth and width [going around your septic requirements], and drop in such a cable to lay in 'once and for all' power to your pond. Put inside a conduit, or not? *IF* you do, arch the conduit [like a piece of plumbing pipe] so that at each end water can run out to a void area underground [upside down plastic 'bubble'.] Seems like a lot of extra effort, but long run will be worth it. And, I mean long run. The problem can be seen, just envision a conduit that goes down, comes back up, as though it were a buried water hose with wires running through it. Long term collect water and just asking for trouble. If me, I'd use heavy pvc conduit to shield the cable [cables cost way too much to allow accidental nicking] That way, if you forget and accidentally hit the pvc it's sacrificial. |
