UFB cable is engineered for use immediately underground with out conduit or raceway. It has a really sturdy PVC jacket that covers every of the conductors individually for added safety. They is even a naked copper floor wire in UFB cables with out insulation which is absolutely protected by the sturdy outer jacket. The pricing of every cable goes so as of surroundings deeming NMB cable the most cost effective, then MC cable and eventually UFB cable is the most costly.
