World electrical rules compared

Comparison articles: PUE vs NEC, IEC, Chinese GB and Indian IS 732, worldwide sockets and voltages, RCDs by country — tables and key differences.

PUE vs NEC: differences between Russian and US rules
PUE (Russia) vs NEC (US): 230/400 V vs 120/240 V, Schuko vs NEMA sockets, 30 mA RCD vs 4–6 mA GFCI, AWG vs mm² — key differences in tables.
PUE vs IEC 60364: differences between Russian and European rules
PUE and IEC 60364 are close (PUE-7 harmonized), but differ: voltage drop, mandatory verification, bathroom zones, EU national codes.
PUE vs China (GB 50054): differences between Russian and Chinese rules
PUE vs Chinese GB standards: 230/400 V vs 220/380 V, Schuko vs GB 1002 sockets, 30 mA RCDs match, fire RCD 300 vs 500 mA.
PUE vs India (IS 732): differences between Russian and Indian rules
PUE vs Indian IS 732: voltage matches (230/400 V) but sockets, earthing (TT vs TN-C-S), minimum sections and testing differ.
NEC vs IEC: differences between US and European rules
US NEC vs European IEC 60364: 120/240 V vs 230/400 V, GFCI vs RCD, AWG vs mm², verification, lightning — key system differences.
Sockets and voltages worldwide: complete country table
Voltage, frequency and socket types by country: Russia (C/F), China (GB 1002), India (IS 1293), US (NEMA), Europe (C/E/F/G), Japan (A), Australia (I) — table and compatibility.
RCDs worldwide: requirements by country
RCD requirements by country: Russia 30 mA (PUE 7.1.79), Europe 30 mA (IEC 4-41), US GFCI 4–6 mA, China 30 mA, India 30 mA, Brazil 30 mA — table, types, fire RCDs.
China (GB) vs USA (NEC): rules compared
Chinese GB standards vs US NEC: 220/380 V vs 120/240 V, GB 1002 vs NEMA sockets, 30 mA RCD vs 4–6 mA GFCI, mandatory clauses vs code inspections.
Europe (IEC) vs India (IS 732): rules compared
IEC 60364 vs Indian IS 732: voltage matches (230/400 V) but sockets (E/F/G vs D/M), earthing (TN vs TT), verification (EICR vs IS 732) differ.
PUE across CIS: Russia, Belarus, Kazakhstan — differences
How PUE applies across CIS: Russia (PUE-7), Belarus (TKP 45), Kazakhstan (PUE RK), Uzbekistan and others — common roots and national differences.
