The DLO cable is very different from the THHN cable because they are both designed and manufactured for different daily fights. THHN is commonly used in interior, exterior, and duct applications and remains immobile throughout its useful life. DLO cable, on the other hand, is used outdoors and is commonly handled on a day-to-day basis, giving it some variance in the amount of protection and user manageability.

THHN is dual rated with THWN as a nylon sheathed thermoplastic patch cord. Thick bare copper strands, or even a single solid, copper strand create a rigid electrical cable for easy installation in conduit. Pushing a flexible cable through conduit will be very difficult.

Since DLO cable is handled by the user on a day-to-day basis, the flexible copper strands help the user get the cable from point A to point B. DLO cable is also commonly wound on a large spool for the day, which gives it another reason to be manufactured as a flexible cable.

DLO stands for Diesel Locomotive Cable which is obviously used in locomotive installations and other applications that require higher than normal voltage. It is a 2000 volt single conductor power cord with EPDM rubber insulation and a second rubber sheath, even though it is a single conductor. The added insulation makes it high-voltage-approved, but gives it an outside diameter that must be considered when installing it in raceway.

Electrical wire THHN 10 AWG It is used in homes and buildings to run power from the electrical box to outlets, lights, and appliances everywhere. Running a single 10 AWG wire is less common than running an NMB cable with multiple 10 AWG wires. Most home and building applications require more than one THHN cable at a time, making NMB 10/3 a common household electrical cable.

You will find in your search that DLO cable is much more expensive than THHN cable. Remember that there will be no difference in price depending on the amount of copper because both are 10 AWG. So the price difference lies in the insulation, construction and approval process. DLO, for example, is UL, CSA, MSHA, and RoHS compliant, while THHN only has a UL and RoHS approval.

Talk to your electrician or wire and cable supplier about the type of wire you need and the AWG size for the application. Choosing it yourself can cause all sorts of problems to be encountered during the inspection process, so make sure everything is done right the first time.
