in this exciting episode,BCB is wondering about the capacity of the different electrical cables to carry current. my riveting question is>>>>> is 240volt x 10amp cable bigger, stronger, more capacity,,than>> 12volt x 10amp..???? if so, what capacity does the 240voltx10amp equate to?? re 12v?? thanking you BCB ptpro some men see things as they are, and ask "why" I dream of things that never were, and say, "bloody ripper idea mate, lets try it",!!

Current and insulation level is all that matters with cable. 10A is 10A regardless of voltage, assuming the insulation is suitable. Low voltage cable (in AC low voltage is 50V to 1000V) is expressed in terms of insulation to earth/line eg 0.6/1kV cable is Edited by user Friday, 15 February 2008 5:28:49 PM(UTC)

multiply amps by volts give you the wattage rating, used for appliances, eg 100 globe/ 2kwatt heater, wire only cares about amps carried and insulation protecting it from earthing
if using 240 volt wire in auto best to use 1.5 to 2.5mm square multistrand

You can buy flexible V105 wire from electrical wholesalers. It would do the job.

If you pick up an Olex pocket book catalogue from an Electrical wholesaler, you will find all types of cable from flexible multi strand through to heavy welding cable which is suitable for battery connection. The Olex pocket book is available free of char

I know very little about leccy but as a rule of thumb if the wires are getting very warm or hot they are too small. the heat is wasted power and the appliance is not getting full power. use larger wire. or double it in the case of figure 8 (normal househ

I went to bunnings, and being a tightrrse, bought one of those 15amp 20mtr, power leads, for $15,
gave me about 60mtrs of coloured striped cable,?
thats why i was asking, about current capacity. but it is fairly thuck, as the kiwis wou |

Volts X Amps = Watts
Watts / Volts + Amps.
Therefore if your going to run a pair of 100wat spotlights on you car, you divide 200watts(2lights) by 12 so thats 16.6666666, so you should run 20amp wire.
Works the same for 240. Which is why most heaters et

Not that simple for AC. Actual AC power measured in VA (or often kVA) is AC volts x AC current for single phase, and volts x current x sqrt3 for 3 phase. In AC systems Watts is referred to as real power and is equal to the Power in VA multiplied by the po |
