4.6.1 Neutral isolation 
HV Generating Units directly connected to the Distribution System shall have their neutral 
effectively isolated from earth (i.e. isolated or earthed via high impedance). This is to limit any 
contribution to a Distribution System earth fault, and to inhibit the flow of harmonic currents through 
the neutral.
4.7 Device approval and compliance 
This section sets out device approval and compliance requirements for all Classes of EG systems. 
4.7.1 Protection equipment 
Protection equipment shall operate the Isolation Device either directly or through interposing 
equipment. Such protection equipment and any interposing equipment shall have certified 
compliance with the following: 

IEC 60255-1 Common requirements; 

IEC 60255-26 EMC requirements; 

IEC 60255-27 Product safety requirements; 

IEC 60255-127 Functional requirements for over/under voltage protection; and 

IEC 60255-181 Functional requirements for frequency protection. 
Marshalling of protection trips through control equipment shall be compliant with IEC 60255.
