Romex cannot be used in the situation you describe as buried conduit is considered a wet location. You must use conductors such as THWN. Also, minimum burial depth for conduit (PVC I assume) is 18″, unless you run rigid or IMC, in which case you can go a minimum of 6″.
Can you use indoor Romex outside in conduit?
Yes, they can be used outdoors, it is better to be safe than sorry. We recommend using a conduit when running the wire underground. Not only is it code, but also a good practice to ensure long life of the wire.
Can you use indoor wire in conduit underground?
It’s important that you follow National Electrical Code (NEC) rules when running an indoor wire through a conduit outdoors. You need to ensure that the conduit is buried deep enough within the ground: 24 in. of earth cover for a UF cable, 18 in. of cover for a PVC conduit, and 6 in.
Can you use regular wire in underground conduit?
At 18 inches, you can use THWN-2 conductors inside a continuous length of PVC conduit, which protects the wire all the way through the trench to the house. At 24 inches you can bury underground feeder cable, using PVC conduit to 18 inches below ground only where the wire comes up.
Is it OK to run Romex in conduit?
No, you can not run your Romex wiring in conduits.
Does Romex need to be in conduit outside?
It’s rather common to protect or shield Romex with PVC in locations where (wet or not) it might be harmed by objects or people, but if you’re going to be running high voltage (120 V+) outdoor lighting or receptacles it’s a much better idea to just use UF, or PVC conduit and pull the THHN conductors through it as you …
What type of wire can be buried in conduit?
THWN-2 wire
THWN-2 wire, for example, is a standard type for running through underground conduit. Use thick-walled conduit at least 3/4 inch in diameter for this application. Never use thin-wall EMT conduit for underground applications.
Can I run Romex in PVC conduit underground?
Romex cannot be used in the situation you describe as buried conduit is considered a wet location. You must use conductors such as THWN. Also, minimum burial depth for conduit (PVC I assume) is 18″, unless you run rigid or IMC, in which case you can go a minimum of 6″.
