1. Packing and transport

The circuit-breaker is shipped in special packing in the open 
position,  with  the  springs  discharged  and  with  the  absolute 
pressure of the pole corresponding to the service value. 
Each piece of apparatus is protected by a plastic cover to 
prevent water from infiltrating during the loading and unloading 
stages and to keep the dust off during storage.
