what kind of wire doi need to bury electrical

It's not uncommon to desire to run 120V electrical wiring clandestine. You may want to send power to your shed, workshop, or garage. Some other common use is running ability to a lamp post or an electric gate motor. In either instance, you should be aware of a few hush-hush wiring requirements in order to meet nearly current edifice codes. We show yous how to install hugger-mugger electrical wiring from one location to another.

Underground Wiring Requirements – How Deep Practice I Bury the Wire?

The commencement question we always become asked is "How deep do nosotros bury the wiring or cable?" That's a peachy question. And the respond is that it depends on what wire you use and whether you run information technology inside a conduit or not. Since most people ask the question so that they can meet a particular want for maximum burial depth, let's start there. Breaking it down by how deep yous bury the underground electrical wiring when you install it, we have the following options:

24-inches Deep Burial Depth

• Use straight-burial secret feeder cable at 24-inches deep (or more than). You lot don't need to use conduit at this depth with UF cable, yet, you exercise need to provide PVC conduit on your vertical feeds starting at 18-inches.

eighteen-inches Deep Burial Depth

• You tin can run THWN-2 conductors inside of PVC conduit at just eighteen-inches deep in the ground. This protects the wire from damage in the outcome someone digs overtop of the cablevision. THWN-2 is basically water-resistant THHN (Thermoplastic High Heat-resistant Nylon-coated wire)

12-inches Deep Burial Depth

• At 12-inches deep, yous tin run straight-burial feeder cable wire that is GFCI-protected. Protect information technology with PVC where it pops up at the house, garage, or shop.

6-inches Deep Burial Depth

• If you lot use galvanized rigid EMT (metallic electric conduit) with individual conductors inside, you tin can bury information technology just 6-inches deep. The thought here is that the EMT can withstand a shovel or other significant potential cause of shorting the wiring.

Full general Notes on Burial Wire

If you always want to use metal EMT conduit in identify of PVC, you can. Typically, we use gray 3/4-inch PVC for a unmarried line. In add-on, while the required burial depths listed in a higher place should be by and large accurate—check local edifice codes first. You want to be admittedly certain you're in compliance earlier you get started. Nosotros typically prefer using PVC conduit when running power to a remote location underground. That gives yous a lot more protection over directly burial cable in the long run.

In the end, just understand your options and take the safest or simplest route depending on your state of affairs. If yous can get abroad without conduit and the wiring is in an area that isn't liable to go in the style of future earthworks, so straight-burial cablevision might be best. If y'all're running through the middle of your yard, a PVC or metal conduit might seem the better choice—fifty-fifty if it's overkill.

Steps to Installing Underground Electrical Wiring

Nosotros don't provide a ton of steps to installing underground electrical wiring. Installing the wiring or conduit takes a lot of work—but not a lot of detailed instructions.

Call Before You Dig!

Don't forget to program alee and telephone call earlier you dig. Yous don't want to hit any buried water lines, electrical lines, sewage drains, or anything else. In most municipalities, they volition bank check your holding inside a day or two for free and when you phone call. Marking out critical lines with flags before you start really saves y'all a lot of hassle and headache. Don't skip this step!

Excavation the Trench

If yous take someone y'all desperately desire to torture, or you lot're just going several anxiety, then using a trenching shovel works just fine. If, still, you lot need to go a good amount of distance with your buried electric cable, we recommend renting a trencher.

Yous can rent a 24-inch trencher in most places for less than $200 a day. You lot tin even pay less if you only demand information technology for a few hours. It saves you countless hours and hassle, so if you can afford it, grab i at your local tool rental store.

Using the trencher, plan your form and dig the trench where yous plan to run your direct-burial cable or PVC pipe.

Cutting Your Ingress or Egress Holes

Cutting your egress and ingress holes from the starting point (for example, your electrical panel) to the end of your run.

Information technology helps to utilize what'southward known every bit a PVC conduit outlet body (LB).

These make it easy to feed wire into a edifice (either the source or the destination garage or shop). Yous just remove the plate using the two screws and feed the wire as needed without having to worry near making a sharp correct-angle turn at the bespeak of entry.

Pro Tip: Employ a rut gun to bend PVC conduit if you need to brand a bend to get up against the firm, garage, or workshop with your pipe.

Feeding Your Wire

Many times you can only push your cable through minimal runs of PVC conduit. If needed, you tin can use a metallic fish record or even vacuum a pull line though the pipe and use that to pull the wires through a long run.

Finish Off Your Connections and Conduit Fittings

After pulling your wire, brand your connections to the electrical console and finish your conduit fittings. That includes securing the plates on your PVC conduit outlet bodies. Test your run, and pat yourself on the back for a job well done!

Concluding Thoughts
