Shore connection set stainless steel 16A

Based on the maximum load for onboard power consumption, choose either a 16 A or a 32 A connection. 
For high loads choose multiple parallel connections to the grid. 
Choose the appropriate connection: Standard is an earthed two-pole plug or the more familiar blue CEE three-pole plug.
