Three phase socket query

[Lc1]

Hi,
We have a three phase 400v socket rated at 63A. It is proposed to use this for a mobile skid. There is an 18.5kw motor and an approximate estimate of current is 34A, the supplier is saying that the socket is not rated high enough as the skid has dual redundancy ( two 18.5kw motors) and as such should be rated minimum 68A. Is it just me missing something as both motors should never be on at the same time? I believe here will be no issues with the socket.

I would get the spec of the client to see what's need in black and white. Redundancy to me is that if one should fail the 2nd should kick in. Is this an Atex certified skid?

There’s maybe details on manufacturers instructions on the supply requirements
