Matches

Voltage 230/400 V, 50 Hz; 30 mA RCDs for sockets; similar copper sizes.

Sockets

IS 1293: three round pins (6/16 A), BS 546-compatible. Russian Schuko plugs need adapters.

TT vs TN-C-S

India: local earth electrode (TT) per IS 3043 — common in homes; Russia: TN-C-S standard. TT requires RCDs by definition.

Sections and testing

India allows 1.0 mm² for lighting; licensed electricians mandatory; testing per IS 732 section 10.
