USE-2/RHW vs THHN | Mike Holt's Forum
Correct on the USE, it can't be used inside unless it also has another rating that is allowed inside. RHW is allowed inside. THHN can't be used outside the building unless it is dual rated - typical is THHN/THWN/THWN-2.
One more time: USE-2 indoors? and, in conduit, or exposed?
I've read all the threads I can find on this, and I'm still confused. With cable commonly referred to as "mobile home feeder cable," or hereabouts also commonly referred to as "URD," and technically described by Southwire as "four quadruplexed type RHH or RHW-2 or USE-2 ... sunlight resistant"
electrical - Is USE-2 or RHW-2 individual wire fit for direct burial or ...
I see companies selling USE-2/RHH/RHW-2 individual wires. Many claim they are fit for direct burial or fixation to joists. They are individual wires, and lack an outer jacket like SE-R or MH feeder has.

What does "use wires" mean?
USE wires are pretty simple, according to the NEC. U: Underground. S: Service. E: Entrance. So, USE cables stand for underground service entrance cables. Again, for cables to be used underground, they must be able withstand pressure and other elements.
What is R wire?
This rubber outer layer is very important when it comes to copper cables, especially when those cables are utilized in possible hazardous environments. Performance Wire and Cable’s RHW-2 wires are insulated by cross-linked polyethylene. Even though the “R” stands for rubber, it also incorporates other neoprene insulations ...
What is the difference between RHH and RHW?
RHH cables are very similar to RHW cables, with two major differences. While only one letter is different in the respective codes, keep in mind what we talked about above. We already covered that the “R” stands for a rubber insulation and the “HH” details the heat resistance.
How hot can RHW cables withstand?
So, RHW cable is a wire is insulated by rubber or something else (XLPE), can withstand heat up to 75 degrees Celsius, and is water resistant. That’s why RHW cables are regularly found underground in wet locations. However, the NEC lists RHW-2 as having the ability to withstand heats of up to 90 degrees Celsius, ...
What is the voltage rating of RHW-2?
RHW-2 wires are suitable for direct burial in both wet or dry locations. Along with RHH cables, they hold a 600 voltage rating. Both cables can be found in general wiring applications, lighting and power systems – depending on the location and surrounding environments.
What does the W mean on a wire?
W: Water resistant. Depending on location, this factor could be the most important for your wire. The “W” label even suggests that the cables can be submerged in water if needed. Even if the wire has “R,” which means it is acceptable to use in damp locations, it is wise to keep these wires away from water if the “W” isn’t present. ...
How hot can a wire resist?
You’ll occasionally see “HH” on some wires, which details the wire’s ability to resist heat up to 90 degrees Celsius. The insulation’s length and width help determine its heat resistance. The thinner the XPLE is, the less resistant it is to heat.
What is a USE-2?
USE-2 can be used as RHW-2 or RHH cable at temperatures up to 90°C in wet or dry locations. What does the “-2” stand for? It is a designation used for the 90° C temperature rating. In the past, there was a plain USE, but it is now generally considered obsolete and replaced by USE-2.
What does W mean on a wire?
W = Water Resistance. Possibly the most important factor when considering the environment of your wire. The “W” means the cables can be submerged in water if needed. Even though the wire has a rubber outer layer and is acceptable for use in damp environments, the “W” designation is required for use in the presence of water and other liquids.
What is RHW cable?
RHW – RHW cable is a wire insulated by rubber or XLPE as mentioned above. RHW cable can withstand heat up to 75° C, and is water resistant. It is acceptable to use RHW cables underground and in wet locations.
What is the outer layer of copper wire?
A rubber outer layer that is very important when it comes to copper cables, especially when those cables are utilized in possible hazardous environments. Like XHHW and XHHW-2, RHW-2 wires are insulated by cross-linked polyethylene (XLPE). Even though the “R” stands for rubber, it also incorporates other neoprene insulations that XLPE falls under.
Does RHH cable have water resistance?
The trade-off is that RHH cable does not possess the water resistance characteristic of RHW / RHW-2 cable. Similarities: Both RHH and RHW / RHW-2 cable hold a 600 V rating. Both cables can be found in lighting, power systems and general wiring applications – depending on the location and environmental conditions.
