When choosing the best wire for the task, make a point of choosing wires with a wet rating. Although you’re not building a commercial building, since the wire will be relatively exposed to the elements and animals, for your own safety, run just one wire per conduit.

When wiring, you will run a single wire per conduit, which is code requirement for all commercial buildings. Yes, it’s economical and is a nonmetallic wire, but Romex isn’t suitable for outside use. We have discussed Romex wires quite a bit in our blog, but it is important to note here that you can’t just run Romex wire when running electrical wire under outdoor decks. Let’s look at these instructions in a bit more detail. It is essential that you fasten your wiring parallel to the joists and not your deck’s floor to eliminate any chance of a mishap. If the wiring is above ground, conduits will have to be fastened to the underside of your deck at least 1 foot high and must not be sagging at any point. Under both circumstances, it is essential that you use external grade wiring and run it through conduits. That way you'll know when the hose is centered over the splice.If we are to look at the code requirements for running electrical wires under outdoor decks, they offer specific guidelines for above and underground wiring. To get the hose over the center of the splice, if the hose is 6" long, mark the cableģ" from the splice with a marker. Just slip it back on the cable, away from the splice a foot or so. Be sure to put the hose on the cable BEFORE making the splice.
You want enough room around the wire to coat everything with the silicone inside. 3/4" should fit any standard #14 or #12 UF cable. It was still working when I moved.īe sure the heater hose is thick enough to fit the taped glob. I never had problems with it, but a year and a half later I moved. A few days later I filled the hole with soil. I did not fill the whole for a few days to let the silicone completely dry, (leaving the plastic bag under the splices). Then I repeated this process on the other splice.

Then I layed it on a plastic bag so the silicone did not get all full of the soil. Then to be sure it was totally waterproof, I used a thin stick and pushed the caulk all the way around the cable, moving the cable from side to side, and finished by applying a big glob of the silicone around both ends of the hose. I slipped the hose over the splice, and using a caulking tube of 100% pure silicone, I inserted the tip of the caulking cartridge in one end of the hose between the wires and the inside of the hose, and pumped the whole thing full of this silicone till it oozed out the other end.
Then I spliced and soldered the replacement piece to all 3 wires, and taped each one with electrical tape, followed by taping the whole bundle. Then I slipped about 6 inches of automotive heater hose over the end of the cable. I had to make two splices because I had to replace about 5 feet where the wires was all chewed up from the tiller. This is probably not up to code, but it worked fine for me, when the upstairs neighbor cut the wire to my shed with his rotatiller when tilling his garden (making it larger than it was originally). I've found a couple splices Dad made in the 60s or perhaps even earlier with just twisted ends and friction tape topped by electrical that are still fine-the reasons for finding them had nothing to do w/ the splices themselves but either modifications/additions or in one case, the actual underground cable sheath itself was failing all along it, it turned out was the cause of the failures causing line to be dug out.they are buried pretty deep (24" +) so that they are not ever in standing or thoroughly soaked ground for any length of time if ever, however, but I suspect they would last a long time no matter what given the condition they're in after 40-50 years. The are, as above says wrapped very well besides just the silicon in the caps. It was an evening, of course, so only choice was an Ace Hardware-the equivalent of the Dr圜onn have held for 8 years or so, so far. I managed to find the control wire from the pump house to the well w/ the post hole digger-no mean feat in a 200-yd run either way to select where to stick a post for a new garden plot fence.
