1. Packing and transport 

The circuit-breaker is shipped in special packing, in 
the open position and with the spring discharged.
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.
