Which Cables Can Be Directly Buried?

“Can this cable be directly buried?”

We get asked this question all the time, so we’ve come up with an answer for everyone.

We often get questions about whether a certain cable qualifies as direct burial. We’re always happy to answer these questions because we know it can get confusing – aside from a few cables (like UF-B and URD) that are always appropriate for direct burial, there are many, many more that are equipped with a sufficient jacket to be rated for direct burial.

Choosing between THHN & XHHW wire

Floyd_Mayweather,_Jr._vs._Juan_Manuel_Márquez

Weighing the differences between THHN/THWN-2 & XHHW/XHHW-2 building wire

When it comes to building wire, two of the most common and popular choices for electricians, engineers & homeowners are THHN and XHHW (or the newer and improved THWN/THWN-2 and XHHW-2). These cables come in both copper and aluminum, can have solid or stranded conductors, and are mainly used for power distribution up to 600 volts in the construction of residential, commercial, and industrial buildings.

While these two wire types are very similar and often interchangeable in their application, the differences are important to know in order to make the smartest decision when making a building wire purchase.

How Our Customers are Using SER Cable

Hey everyone, Willie the Wire Guy here. Lately, I’ve been keeping in touch with a number of our customers who have purchased wire and cable products for a couple of reasons: (1) to make sure they’re satisfied with their wire and cable, and (2) out of curiosity—to see how our products are being used. I’ve received awesome feedback, and I’m glad to see that people find our wire and cable performs at a high level.

It’s also been great to see the kinds of projects people are undertaking that have made them need our products in the first place. I thought it’d be a good idea to share this information for anyone who might be tackling a similar electrical project so that they can learn what type of wire others are using. Today, we’re going to focus on our Aluminum Service Entrance Cable with reinforcement tape (or SER Cable) and how Wire & Cable To Go buyers are putting it to use.

Wire & Cable Glossary

What do the ‘M’ and ‘C’ in MC cable mean? What does XLPE cable stand for? Why is it called SOOW cable? Answers to these questions and more!scientists

The world of wire and cable has a language of its own, and even those with experience need a translator from time to time. Your old pal Willie knows this to be true, so I’ve compiled a cheat sheet on wire and cable nomenclature for you to reference.

First, we have a list of individual descriptors, each either made up of one or two letters. These can define what the cable is used for, what it’s made of, or what the cable can withstand––like heat resistance or voltage ratings. Often, a cable’s name will be some combination of two or more of the descriptors below.

The Components of Wire & Cable Nomenclature

E: thermoplastic elastomer
FF: flexible fixture
H: heat-resistant 75ºC
HH: high heat-resistant 90ºC
J: junior service, rated to 300 volts

Type NM-B (Romex) Cable

Romex Cable

Type NM stands for nonmetallic sheathed. The cable consists of a factory assembly of two or more insulated conductors within an overall nonmetallic jacket. Additionally, there is an equipment-grounding conductor that is bare or has green insulation. Type NM is identified by the size of the conductors and number of them. For example, the very commonly used Type NM 12-2 cable contains two 12 American Wire Gauge (AWG) insulated conductors. In this numbering system the bare or green equipment-grounding conductor is not counted. Hence it is known as NM 12-2 w/ground.

Closely related cable types are Type NMC, which has a corrosion-resistant outer covering, and Type NMS, which contains, in addition to the usual power conductors, communications (signaling) wires. When the letter B is appended, as in NM-B cable, it indicates that the conductor insulation is rated for 90 degrees C.
