Power Mains vs USA Power color code:  Euro :  E - Earth (Yel/Grn) or (Green),    N -  Neutral (Blue),    L - Live  (Brown)
                                                                   USA:  G - Ground (Green),  N - Neutral (White),  H - Hot  (Black)
                                                                  [ the USA calls it "(G)eorge (W)ashington (B)ridge" easy to remember! ]


NOTE1:  Since the USA no longer has an electronic magazine, (i.e. Popular Electronics, Radio Electronics, Modern Electronics, Electronics NOW, Poptronics).
                I have had to resort to the UK's EPE magazine, ( Everyday Practical Electronics.)  However, EPEMAG now comes as a PocketMag fileNO .PDF!!!!
                This is an ABSOULTELY 'AWFUL FORMAT!'  So I'm NO LONGER getting it!  It's UNREADABLE, and you CAN'T download it to your Computer!

                Their is "1" exception here in the USA, and that is: * Nuts&Volts *.  
                Also, however...HAM Radio does not have the following it used to have, since it takes a bit of studying to get a License, and kids now-a-days DON'T like to study!


NOTE2:  Europe or (Australians)  vs  USA
  •     When an article says they're using "Screened Cable"; we say "Shielded Cable"
  •     A "Supply Rail" in Europe country's is equal to the "Supply Voltage Buss" for the US
  •     A European "Plugpack" or "Power Brick"  is equal to our "Wall Wart"  (Transformer pack)
  •     "Shield Earth" or "Earth Wire" is the same as our "Earth Ground"
  •     "RLA" Euro.;  is equal to "Relay" in the US
  •     "Resistance Tester" is equal to our V.O.M. (Volt Ohm-Meter)
  •     They have a "Battery Box", (an External Box containing Batteries); we have a "Battery Holder"
  •     We both have "Crystal's" and "Resonator's"
  •     What they call "Valves or "Heaters"";  we call "Vacuum Tubes". And they call "Most Positive Anode";  we call  it a "Plate".  We also call the "Heater" a  "Filament"
  •     Their "Earthing Lug" is equal to our "Grounding Lug"
  •     On Electrical Equipment, Euro. may say "Power Switch", or just "Power"; we usually call it a "Power Switch"
  •     "Mains" is the "AC Power" coming into a building; we call it from a "Power Station", and that is fead by a "Power Grid"
              NOTE: They push their Switch's "Down for ON";  we Flip them "Up for ON"
  •     They say Aluminum Heat Dissipater or Heatsink;  we say Heatsink    (This was actually printed in EPE Magazine.)
  •     (8 off) means you need "8" of that item.  HUH!
  •     They say "Duff Item" is a "Dead Item", "Knackered", "Goosed", "Hosed" ,"Spannered" or "Buggered"; we call it a "Dead Item" or a "Hosed Item"
  •    They say "Ring Core's";  we call them "Toroid's"
  •    The say "VAT" (Value Added Tax);  we just say "State Tax"
  •     The say "Carriage Charge" or "Shipping";  we say "Shipping and Handling" (S&H), or just "Shipping"   
  •     They say "Shipping" or 'Postage and Packing' (P&P); we say, just "Shipping"
  •     They say "2000 Tonnes" metric measure equivalent to 2,000,000 KG or 1,968 UK Imperial; we say "2,205 US Tons"
  •    They say "PaperShop" or "Newsagent"; we say "Magazine/Book Store"
  •    "Protective Conductor" or "Eth": Yel/Grn;  we call "Ground Connection": Green  (Grn)
  •    They say "Meteorological Office";  we say "NOAA Weather Station"
  •    The say "26-Way Ribbon Cable"; we say "26-Lead Wire Ribbon Cable"
  •    Australians say "Rat it out"; UK says "Recycle/Recover";  we say "Disasemble to find useful Parts or Items" (This was actually printed in EPE Magazine.)
  •    They say Batteries go "Flat", "Flatt", "Duff" or "Gone" ; we say they are "Dead"
  •    They say "Outer Part of an Enclosure" or "Case";  we say "Box" or "Chassis"
  •    Their "Chassis" is an "inner screen" that is just before the "Electronic Components";  we still say "Chassis"
  •    What they call a "Torch";  we call a "Flashlight"
  •    What they call "Flashes";  we call a "photographic flashguns"
  •    British people draw "Circuit Diagrams";   we call them  "Schematics"
  •    They plug their "Kettles" into a "mains socket";  we plug ours into an "Outlet"
  •    They pay a "charge according to a tariff" or "Freephone";  we use "Toll-Free Numbers"
  •    UK calls small "Variable Capacitor" that is set while adjusting the circuit;  we call them "Trimmer Capacitors"
  •    A "Preset" is a "Variable Resistor" that operates in the same way
  •    Australians say "Trimpot";  we call them "Variable Resistors"
  •    Australian articles refer to as "PC Stakes".  Europe and the US call them "Terminal Strips"
  •    British circuits are drawn with the highest-voltage power rail as a horizontal line at the top of the
       page, the ground rail being at the bottom. Old American diagrams put the HT rail just below ground, with lots of  vertical
       lines going from the top of the page down to HT. Australians don't even have a ground rail, they just finish each connection in a
       ground symbol, giving the impression of a row of flower-pots!  That's funny!!! :D
  •    We say 9V Rectangular Battery, they say 9V PP3

  •   Europe uses 220VAC, they have problems with 'Switch Burn-out', the US uses 120VAC, so we don't have that problem

  •   Europe says "Wide-Range Speakers", the US says "Full Range Speakers"
  •   Europe says: plastic "Zippy" box, the US says "Plastic Case or Plastic Enclosure"
  • Europe says "anticlockwise", the US says "Counter-Clockwise"
  • Europe turns off their light switches flipped up, the US turns them off in the down position
  • Europe, having switches turning ON/OFF at 240V, tend to arc more then we do here in the US at 115V

  • Revision of projects. US says "Rev" - EU calls it "Mk"
