Type RHH or RHW-2 or USE-2 conductors are used with conduit as specified in the National Electrical Code. When used as Type USE-2, conductor is suitable for use as underground service entrance cable for direct burial at conductor temperatures not to exceed 90° C. When used as RHH, conductor temperatures shall not exceed 90°C in dry locations. When used as RHW-2 or USE-2, conductor temperatures shall not exceed 90°C in wet or dry locations. Voltage rating for RHH o RHW-2 or USE-2 conductors is 600 volts.
Type RHH or RHW-2 or USE-2 copper conductors are annealed (soft) copper. Insulation is an abrasion, moisture, heat, and sunlight resistant black cross-linked polyethylene (XLP).
What does “USE-2 RHH RHW-2” stand for in USE-2 RHH RHW-2 Copper Conductor Building Wire?
What are the common applications of the USE-2 RHH RHW-2 Copper Conductor Building Wire?
You can use this cable in a lot of applications, but they are most preferred for use in solar applications where it is used to connect photovoltaic modules which are grounded. You can also use them in underground conduits.Also, you must be careful to see that the cable that you are using for your projects matches the specifications you need to follow.
Is the USE-2 RHH RHW-2 Copper Conductor Building Wire superior to its aluminum counterpart?
Conductors made from copper and aluminum have both advantages and disadvantages. So there are some cases where copper works better and some places where aluminum is preferred. For example a copper wire can do with a smaller conduit and less insulation while aluminum will require more as the diameter of the wire will be larger for a cable of the same caliber. In some cases, aluminum cables are used rather than copper as they are more flexible, but copper cables save more energy and will dissipate heat faster. So it really depends upon the type of job that you want the cable to do to select the cable.
What are the standards that the USE-2 RHH RHW-2 Copper Conductor Building Wire matches?
The cable is made keeping in mind all the industry standards such as the following –
What are the environmental factors that the conductor is resistant to?
The Copper Conductor is resistant to extreme heat, sunlight and moisture. This is enabled by the Cross-Linked Polyethylene (XLP) Insulation protecting the conductor.
