The machine install itself will still be subject to testing albiet via the relevant BS60204, when the controls are energised after install and dependent on the machine design and layout as to what requires testing the Annex A of the BS60204 explains all the required testing procedures and confirmations and yes it does somewhat mimic the BS7671 in some of its wording or vice versa (chicken or egg).
On installation you still have to ensure the integrity of the electrical system you have just fitted again the extent of your testing is subject to machine/control design, exemptions do exist - Where the calculations of the fault loop impedance or of the resistance of the protective conductors are available and when the arrangement of the installation permits the verification of the length and csa of the conductors, verification of the continuity of the protective conductors can replace the Zs measurement.
Even having motors running of drives where you cannot do a practical measurement then you will still need to confirm the continuity of the protective conductor.
If you are as in the OP situation installing a machine line then it would almost definately be subject to required testing procedures if the OP expresses these are not been carried out then the installers or those commisioning the production line are not doing what is required to sign the system over.
