The 16A socket can withstand a motor whose rated current is max 16A.
For 16A and cos phi 0.8, the motor power is about 8kW
And what engine can start on a 16A fuse, it depends on the fuse characteristics: B, C, D, gG ...
Because it depends on what starting current the fuse will withstand. And the inrush current depends on many factors.
Is it about a specific engine? Engine nameplate available?
