What are the differences between NM-B and UF-B cables in terms of their applications and specifications?

NM-B cables are typically used indoors and are suitable for dry locations, while UF-B cables are designed for underground use and can be used in wet locations. NM-B cables have a PVC jacket and are not rated for direct burial, while UF-B cables have a tougher outer jacket that allows them to be buried directly in the ground. Additionally, UF-B cables have a higher moisture resistance compared to NM-B cables.
