The appellant is a manufacturer of electrical cable with its factories and principal offices outside the state of Florida. The appellee, Florida Electric Supply, Inc., is a wholesale dealer in electrical cable in Dade County, Florida, and appellee, E. C. "Red" Cornelius, Inc., is an electrical contractor. Cornelius, through the appellee, Florida Electric Supply, Inc., placed an order and purchased electrical cable from the appellant, which cable was to be buried in the ground and used in connection with an installation being performed under subcontract for the United States Navy by Cornelius. After the wire had been in the ground some eight months, it was found to be defective and several power failures required the removal of the cable. Although all of the cable was not known to be defective, Cornelius, at the Navys request, removed all of the cable and replaced it with another brand or type of cable.
