What wire should I use to replace URD in underground conduit

You’ll need to use individual 6AWG Cu THHN or 4AWG Al XHHW-2 wires with a 10AWG copper ground for that run if you want 50-60A from it.

Can URD wire be installed in conduit?

(All THWN is dual-rated THHN). You simply buy three full-size wires for hots and neutral, and one appropriately ground-sized wire for the ground. Note that URD is simply THHN or XHHW wires glued together. If your conduit is continuous, then gluing the wires together is bad, and works against you.

What cable can be used in underground conduit?

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.

What type of cable is URD?

aluminum wire

Underground residential distribution wire (URD) is an aluminum wire for underground utility systems where it is installed in ducts or conduits for secondary power distribution. The cable consists of several stranded or compressed strands of aluminum wiring (typically THHN or XHHW).

Is URD rated for direct burial?

Wire & Cable Your Way offers URD wire at the best prices you’ll find anywhere – available by the foot with no cut charges. This underground electrical wire may be used for underground secondary distribution and service entrance applications at 600 volts or less.

Can you run aluminum wire in conduit?

USE-2/RHH/RHW-2 aluminum building wire is rated for direct burial and intended for general purpose applications utilized in conduit, underground in conduit, or other recognized raceways for services, feeders, and branch-circuit wiring.

What is the best wire to run in conduit?

THHN

THHN (thermoplastic high heat-resistant nylon-coated) is the best wire for pulling through PVC conduit. Other types of wire have a sticky rubber sheathing that makes them almost impossible to pull.

Can you use regular wire in underground conduit?

You cannot use nonmetallic sheathed cable (Type NM, NMS) in conduit in any damp, or wet location (NEC 2011 300.5(B), 300.9, 334.12(B)(4)). Instead, you’ll want to use individual conductors rated for wet/damp locations.

What is code for underground electrical conduit?

Underground ducts of rigid metallic steel conduit, Schedule 80 PVC conduit, or equivalent, containing cables operating at a potential above 35,000 volts, shall be installed at a depth of at least 36 inches.

What is URD triplex wire?

Triplex Aluminum 600V URD cable is designed for use in secondary distribution circuits, where installed in duct or direct burial applications. Maximum operating temperature is not to exceed 90°C in wet and dry locations. Voltage rating is 600 volts. As an option, this cable can be provided pre-pulled into duct.

What is 2 AWG aluminum wire for?

#2 Stranded Aluminum XHHW-2 Wire
XHHW-2 are primarily used in air duct, conduit or recognized raceways for services, feeders and branch circuit wiring as specified in the National Electrical Code.

How many amps is #4 aluminum good for?

Allowable Ampacities of Insulated Aluminum or CopperClad Aluminum Conductors

Can aluminum wire be used underground?

For underground cables, only two metals are used: copper (Cu) and aluminium (Al), due to their excellent conductivity. The best metal for conducting electricity is actually silver.

What is the best wire to run underground?

We typically prefer using PVC conduit when running power to a remote location underground. That gives you a lot more protection over direct burial cable in the long run.

What size wire do I need for underground?

Sizing the wires, or conductors, for an underground cable is no different than sizing for other household circuits and is typically based on the total load, or electrical demand, of the devices on the circuit.
For 120-volt circuits:
