Scope

This part of GB/T 38428 specifies the technical requirements such as type and size, structure, electrical performance, and mechanical performance for DC plugs and sockets used in information and communication technology (ICT) equipment installed in data centers and telecommunications centers.
This part applies to Class I equipment with two live contacts and a grounding contact, with a rated power not exceeding 4.0 kW and a rated voltage range from 240 V DC to 400 V DC. They are only used for DC power in accordance with GB 4943 for ICT equipment and products.
According to this part, only when the DC voltage distribution system meets the following requirements can ordinary personnel in data centers use electrical accessories:
——Equipment with a voltage of (380±20) V, without a backup battery and a voltage regulation system.
——380 V equipment with a voltage range of 240 V to 400 V, equipped with a backup battery (which cannot guarantee voltage regulation).
——During normal operation, the voltage value between each live conductor and the grounding does not exceed 200 V DC.
——With 2 abnormal voltage ranges (lasting less than 10 minutes):
According to this part, there is no need for maintenance of the accessories.
The plugs and sockets within the scope of this part are suitable for circuits that have implemented the following protections:
——Basic protection;
——Overcurrent protection (based on a maximum current of not more than 16 A per socket);
——Fault protection (indirect contact protection); and
——Additional protection.
This part does not include requirements for concealed installation boxes, but only for exposed installation boxes required for testing the sockets.
