Power and control cable for fixed installation in the following applications:.The inspector will verify that your conduit is buried to the proper depth, then give you the go-ahead to fill in the trench and continue with the circuit installation. Before filling in the trench, make sure to have it "passed" by the inspector, if this is required by your local Code.Leave plenty of excess cable at each end of the conduit run, to allow for an electrician to continue the hookups inside the house and inside the garage.Applying cable lubricant will make it easier to pull the cable. Having a helper feed the cable from one end as you pull on the fish tape makes this job much easier. Attach the end of the UF cable (or individual THWN wires) to the end of the fish tape, then carefully pull the cable back through the conduit. Extend a fish tape down through one end of the conduit all the way through to the opposite side.At each end, attach sweep fittings connected to vertical lengths of conduit extending up out of the trench. Lay the conduit into the trench, solvent-welding the joints of individual sections with PVC solvent glue.Then, run the conduit beneath the sidewalk through the hole you bored. If necessary to cross sidewalks, dig the trench down to the required depth on both sides, then bore a lateral hole under the sidewalk by driving a piece of rigid pipe or conduit horizontally.If you have to dig a long trench, you may want to consider renting a trenching machine for this job. Use a trenching shovel to dig a narrow channel from the house to the garage, at the recommended depth for the type of installation you are doing.The shortest, most direct route is always best.
Layout a pathway for the wiring run on the ground from the house to the garage, using rope or a garden hose.It'll resist the growth of fungi, too, and still can handle load capacities of up to 55 amperes. Here, the conduit must be at least 18 inches deep, and again the individual conducting wires inside the conduit should carry a "W" waterproof rating, such as THWN-2. UF stands for underground feeder, and UF wire is specially designed to perform even in soaked and soggy soil and features UV protection from exposure to the sun at connections above ground. Running wire through Schedule 40 PVC conduit.Never use thin-wall EMT conduit for underground applications. Data Sheet January 2019 Applications The 3M Direct Bury Splice Kit DBR/Y -6 is used to electrically connect two or more pre stripped copper wires and moisture seal the connection for direct burial. Use thick-walled conduit at least 3/4 inch in diameter for this application. Premium splice designed to connect and moisture seal an electrical connection for direct bury applications, rated up to 600V.
#Direct bury wire connectors plus
THWN-2 wire, for example, is a standard type for running through underground conduit. 3M Direct Bury Splice Kits combine the quick, reliable connection of a 3M Performance Plus Wire Connector with the moisture resistance of a high impact, UV resistant tube prefilled with moisture resistant grease. In this method, the conduit can be as shallow as 6 inches deep, and the individual conducting wires inside should have a "W" labeling to indicate they are waterproof.
