Will my circuit take appliances drawing 6000 amps? (None sparky)

I just purchased a catering trailer that is already wired up.

The road side supply is a 32amp (commando socket).

Consumer unit in the trailer is fitted with 1 x 63amp / 30mA RCD Incomer (Trip Switch) plus 1 x 32 amp Miniature Circuit Breaker (for sockets) and 1 x 6 amp Miniature Circuit Breaker (for Lighting).

I thought it a little strange but the external socket on the trailer that will connect to the road side supply is a 16amp commando socket.

I was told that the wire from the external socket to the consumer unit is 6mm and I expect the wire running to the sockets from the consumer unit to be 2.5mm.

Given that I need to be able to plug in to the sockets, appliances that will collectively draw up to almost 6000 watts,

1.     Do I need to change my external commando plug from a 16 to a 32

2.     If the wires to the sockets are 2.5mm, will they fry when everything is plugged in and do they need to be changed to 6mm?

 
Most mobile catering trailers have a 16A input connector, most generators only have a 16A socket, although when you add up the rated power of all the appliances it may add up to 6000watts, however in reality when you factor in diversity and other things you probably won't come anywhere near 6000 watts loading.

 
As you have a 32A roadside supply, the best route is upgrade your incoming connector to 32A as well. May mean changing the cable as well as the actual connector.

I guess most of your loads are electric chip ftyers etc So if you turn them all on at once when you set up, that will overload the 16A connector (and cable)
