  1. my home just has good ol' reliable fuses
    9
  2. for example a 1.5mm² cable can easily handle 10a inside a wall but 16a outside a wall
    6
  3. why didn't the uk use screw in fuses like europe & america?
    3
  4. nowadays the uk is also 230v because continental europe was 220v
    3
  5. if it's the 240v single phase split phase then it can work but there's the 60hz problem: if the device says 50/60hz then it'll work just fine if the 50hz device has a motor then it may not work properly or even break if the 50hz device is an ac/dc adapter like an rvl-002(eur), rvl-002(ukv) or rvl-002(aus) then it'll likely still work with 60hz
    3
  6. most european houses (& even some apartments) are actually 400v 3 phase
    3
  7. ​ @j.r.arnolli9734 what about the oven & stove tops on at the same time? that's why european ranges are usually connected to 3x16a 11kw fuses
    3
  8. ​ @nighttow8780  in europe the standard 230v (or 400v) circuits are 16a but 230v 10a circuits also exist because that's still over 2000w
    3
  9. because 2 phases can't normally rotate a motor
    3
  10. ​ @antaress8128 i doubt c25 is the correct breaker size: 1.0mm² c6 (lights) 1.5mm² c10 (lights & sockets) 2.5mm² c16 (sockets & 3 phase ranges) 4mm² c20 (single phase ranges) 6mm² c25 (main)
    3
  11. in europe 3 phase breakers disconnect all phases at the same time
    3
  12. in mainland europe most houses & even some apartments get 3 phase 230/400v 50hz
    3
  13. aren't those just fuses? tulppasulake?
    2
  14. our standard outlets are only 120v
    2
  15. most european houses are 230/400v 3 phase
    2
  16. what? you have c25 breakers? shouldn't they be c16?
    2
  17. ​ @pleappleappleap if the 3 phase motors are 400v 50hz then yes
    2
  18. having fuses in plugs is unsafe because if they keep blowing then people will use bigger fuses
    1
  19. an elcb only detects current in the earth wire unlike an rcd
    1
  20. ​ @AMATISIG what you just described is an rcd
    1
  21. the tv uses the same watts (assuming it's the same model) but it uses double the amps which requires thicker wires
    1
  22. i think it's because for example 12awg is thinner than 4mm² so the american 20a breakers are faster blow than the european 20a breakers
    1
  23. we have 120v 20a 5ma gfci sockets
    1
  24. ​ @DavidLeecl  nowadays we have not only gfci breakers but also tamper resistant sockets
    1
  25. for people who don't speak british english, lift means elevator
    1
  26. our ac units are usually connected to 2 phases so they're 208v or 240v
    1
  27. what do you mean "common neutral"? each circuit has its own neutral wire but they all share a thick main neutral wire
    1
  28. ​ @nicolas073 why would a circuit breaker need to cut the neutral wire? that doesn't make any sense
    1
  29. 2 phases can't normally rotate a motor
    1
  30. my rental apartment is 208v
    1
  31. the difference is so small that the devices will work on slightly different voltage (also most modern devices are 220-240v or 100-240v)
    1
  32. an elcb is obsolete because it only detects current in the earth wire unlike an rcd
    1
  33. ​ @Gazer75 for some reason most uk homes are only 230v single phase even though it makes no sense
    1
  34. ​ @bobingabout in mainland europe even some apartments get 3 phase because it allows for thinner wires (5g6mm² for 3x25a instead of 3g16mm² for 1x50a)
    1
  35. ​ @bobingabout i'm specifically talking about the home consumer unit
    1
  36. do you mean c10 mcb?
    1
  37. it doesn't even make any sense because the nes is 9v & you can use a 100-240v ac adapter
    1
  38. only rated at 10a? where do you live? the schuko plug is rated at 16a
    1
  39. ​ @Mcfreddo do you live in australia?
    1
  40. did you know? a standard b20 breaker is slower than a standard 20a american breaker
    1
  41. converting an ac voltage to another ac voltage is much easier than converting a dc voltage to another dc voltage
    1
  42. ​ @tonchanthol5329 did you know? my range also uses a nema 10-50r instead of a nema 14-50r
    1
  43. here in america most main breakers are either double pole or triple pole unlike european main fuses
    1
  44. 230/400v mcbs exist & you just have to disconnect live wires
    1
  45. are you sure about that? because high voltage dc is rare
    1
  46. i hate 120v because my room is 1800w instead of 2300w & my kitchen is 4800w instead of 7360w
    1
  47. ​ @HelloKitty-x4u6d  our 120v extension cords aren't safe because you can easily need 15a or even 20a of current
    1
  48. most countries use 220-240v because it's more efficient than 110-120v (for some reason japan uses 100v)
    1
  49. what about connecting the lamp's ground to the neutral? tn-c earthing system?
    1
  50. ​ @mastergx1  old homes in finland use the tn-c earthing system where the washing machine circuit is 2x2.5mm² instead of 3x2.5mm²
    1
  51. ​ @mastergx1  the schuko socket is unpolarized but grounded
    1
  52. what's your channel about? i understand finnish but i don't understand you
    1
  53. 12:34 he said that
    1
  54. an elcb isn't recommended because it only trips if there's current in the earth wire unlike an rcd
    1
  55. ​ @ColinDyckes what you just described is an rcd
    1
  56. ​ @ColinDyckes it's not the same thing because of the reason i said, you can say rccb if you want because that's a different name for the same thing
    1
  57. was it a pen fault? if there's a pen fault, turn off your main switch immediately
    1
  58. what's the point of 120v? i hate it because my room is 15a 1800w & my kitchen is 2x20a 4800w
    1
  59. it has l1, l2, l3, neutral & ground
    1
  60. ​ @HBrobjerg if it's tn-c then there's no difference but if it's tn-s then they're kept separate because that allows an rcd
    1
  61. does australia use mcbs? the standard australian socket is 15a but 15a mcbs don't exist
    1
  62. you don't have to cut the neutral wire because it's 0v
    1
  63. ​ @erict1595  i've only seen double pole switches for inlets
    1
  64. i've only seen double pole switches for inlets
    1
  65. ​ @uranium_chunk isn't that tt? i think tn-s is better
    1
  66. ​ @GH-oi2jf what about a microwave oven for example? it consumes about a half of a 120v 20a circuit but only about a third of a 230v 16a circuit
    1
  67. ​ @GH-oi2jf my kitchen only has 2 20a circuits for everything
    1
  68. ​ @pontiacg445 the fridge should be on its own 15a circuit
    1
  69. ​ @EngineeringMindset larger homes in most 220-240v countries get 3 230/400v lines + neutral
    1
  70. dc creates bigger arcs than ac
    1
  71. i know an old finnish apartment which is 1x35a instead of 3x25a
    1
  72. i know an old small finnish apartment which is 1x35a instead of 3x25a with a range which is 1x20a instead of 3x16a
    1
  73. what? the kilowatts would be the same but the wires would be thinner because they'd have to handle less current
    1
  74. ​ @nhitc6832  230v 1x35a is barely enough
    1
  75. parts of brazil are 230v 60hz instead of 120v 60hz
    1
  76. what? do you mean the fuse size?
    1
  77. ​ @breadmoth6443 what do you mean? if the socket is behind a 120v 15a fuse then it outputs 120v up to 15a
    1
  78. that's it instead of tn-s or tn-c
    1
  79. european ranges are usually connected to 400v 3x16a 3 phase & european garages usually have a standard red 400v 3x16a 3 phase socket
    1
  80. that depends on the resistance of the earth circuit but if it's tn-c or tn-s instead of tt then the answer is usually yes
    1
  81. i once measured 135v in europe
    1
  82. ​@soundslight7754 it doesn't really matter because 230v devices can handle anything from 220-240v & heating elements will run slightly hotter than on 225v
    1
  83. trinitron
    1
  84. there's also south korea which is 230v 60hz
    1
  85. i only know finland but rcds didn't exist there until the 1990s
    1
  86. an elcb is obsolete because it only detects current in the earth wire unlike an rcd
    1
  87. that ground fault is just a short circuit if it's tn-c or tn-s
    1
  88. ​ @oliversmith7130 you can't use rcd in a tn-c system
    1
  89. how big is your apartment? mine is 120v 2x60a
    1
  90. the "translate to english" button translates your comment to "not my video"
    1
  91. because that can't normally rotate a motor
    1
  92. don't you use 3 phase ranges?
    1
  93. are you a furry? for some reason an mcb just flips like a switch
    1
  94. a gfci outlet is basically an outlet with a built in 5ma rcd
    1
  95. because we originally only had 110v for lighting
    1
  96. what are you talking about? 208v is 120° out of phase & 240v is 180° out of phase
    1
  97. i think you made a mistake because i know finland: the standard grounded schuko sockets are 16a but they can also be 10a the old standard ungrounded sockets are usually 10a also main fuses in finland are usually either 3x25a or 3x35a
    1
  98. are you talking about british electricity? most european houses (& even some apartments) get 400v 3 phase
    1
  99. 6000a is the maximum current that the breaker can break
    1
  100. 12:34 he said 240v single phase
    1
  101. you're finnish? my dad is finnish
    1
  102. my rental apartment is 120/208v 2x60a
    1
  103. because that can't normally rotate a motor
    1
  104. i know an old finnish apartment which is 1x35a instead of 3x25a
    1
  105. ​ @toraxmalu a 3x16a range has more power than that entire 1x35a apartment
    1
  106. do you live in europe? european garages usually have a 400v 3x16a 3 phase socket
    1
  107. how big are your main fuses? if they're 3x6000w then it makes no sense to just use 1x6000w
    1
  108. ​ @besacciaesteban how many amps are the 3 220v main breakers each?
    1
  109. ​ @besacciaesteban 220v 3x25a is a lot of power (my home is only 120v 2x60a) but 220v 1x25a is almost no power at all
    1
  110. where can i buy a 1200rpm micro motor?
    1
  111. the 3x32a & 3x63a sockets are uncommon because the common main fuse sizes are 3x25a & 3x35a
    1
  112. an elcb is obsolete because it only detects current in the earth wire unlike an rcd
    1
  113. how big are your norwegian 230v range fuses usually? european range fuses are usually 400v 3x16a & our american range fuses are usually 208v or 240v 2x40a
    1
  114. because 2 phases can't normally rotate a motor
    1
  115. rccb is usually called rcd
