  Howdy

  The area (in sq ") of a wire of gauge awg is:
  

  
  
  

  Sum up the areas of the wires in question and then convert back:

  • actual gauge vs. nominal AWG... - Duster 17:11:09 07/19/06 (2)

    Nice post, Ted :-) However, I've never seen a cable's aggregate/effective gauge listed/mentioned in other than 0.5 AWG numerical point increments. I'm no expert, but I think a "nominal" designation applies more towards the intent of the AWG's table rather than a splitting of hairs per an "actual" gauge, so to speak....

    Just my 2.2731 cents :-D

  ...would be the nominal aggregate gauge. The AWG table's numerical designation decreases 3 numerical points each time the cross-section is doubled.

  17 AWG x 6 = 9.5 AWG, since it's cross-sectional increase is between 11 AWG and 8 AWG (a 1.5 numerical point difference):

  17 AWG x 2 = 14 AWG

  17 AWG x 4 = 11 AWG

  17 AWG x 8 = 8 AWG

  The "Simple Wire Gauge (AWG) Calculators" link posted in this thread (link provided again below) can only be counted on to provide an approximate effective gauge, and not always an exact calculation. It's not an actual calculator since it's results are based on a database. Sometimes the figure is exactly correct, sometimes it's not ("closest matching entry") depending on the numbers entered:

  -snip-

  "These calculators don't do any fancy math. They just consult a table of cross-sectional areas for a set of common wire gauges. That means that any reported effective gauges are not exact. To find the effective gauge of a collection of wires, their total combined area is computed, and the closest matching entry in the table yields the result."

  ...time one doubles the number of identical conductors, the gage number changes by 3. So 2 17s = 14g., and 4 17s = 11g. So we're getting close...but...using an AWG resistance chart and the linked parallel-resistors calculator, I calculated that 6 17g. conductors is exactly 9.25 gage.
