If you are looking for the , you are specifically seeking the rules for connecting these generation sources to a low-voltage installation.
The IEC 60364 series is divided into several parts, each addressing a different aspect of low‑voltage electrical installations. Two parts are frequently conflated in online searches, but they serve distinct purposes:
IEC 60364-5-551 specifies the requirements for the selection and erection of generating sets.It applies to low-voltage and extra-low voltage installations intended to supply power to a whole installation or part of it. Key Applications iec 60364 part 551 pdf
When a design specification dictates a specific environment code based on Part 5-51, the designer must translate that code into an IP rating for procurement: External Influence Code Environmental Condition Minimum Required IP Rating Negligible Dust IP2X / IP3X AE4 Light Dust / Small Objects AE5 Moderate Dust / Floating Particles IP5X (Dust-Protected) AE6 Heavy Dust / Industrial Debris IP6X (Dust-Tight) AD2 Vertical Water Droplets IPX1 or IPX2 AD4 Splashing Water AD5 Water Jets 5.
