Does anyone know what type of certificate should be issued with a panel build which will be used on a machine upgrade - is it certificate of compliance or certificate of conformity.

Would the certificate of compliance be issued fro the supply connection to the panel bearing in mind that the panel will comprise of PLC, Inverter drives, power supply and relay etc.

Whatever type of certificate that needs to be issued, I can only think of the normal type of information / tests eg supply voltage, neutral to earth voltage, earth resistance and checks to confirm that the cabling is up to required standards.

What am I missing here?
