Common base

Both derived from IEC 60364 (GB/T 16895 and GOST R 50571). RCD, earthing and sizing requirements are nearly identical.

Voltage and sockets

China: 220/380 V, 50 Hz; GB 1002 sockets (3 flat pins, 10/16 A). Russian Schuko plugs need adapters.

RCDs

30 mA for socket circuits — matches; fire RCD ≤ 500 mA (China) vs 100–300 mA (PUE 7.1.84); TN wall-AC circuits may skip RCD in China (GB 50096 8.7.2).

Acceptance

China: mandatory clauses, incoming inspection, 24 h lighting trial (GB 50303). Russia: PUE 1.8 acceptance tests.
