Wall charger 3 phase only 16a?

So just received my Model 3 and charged for the first time on my newly installed wall charger. my car is only charging at 16a when the charger has been set to its max 32a? Any ideas why this is happening? It is charging at around 44 miles per hour on 3 phase. Does this sound about right?

That's normal from 3 phase. The car can only charge at 16 A per phase on a 3 phase supply, so around 11 kW or so max.

It only charges at up to 32 A from a single phase supply.
