Re: Solid versus stranded Wire



Hi Dave!

At 60 Hz there's no performance difference between solid and stranded
wires of the same gauge. However, stranded would be easier to work with.
The approximate ohms per 1000 feet for these gauges is:

	AWG:	Ohms/1000'
	#14	2.524	
	#12	1.619
	#10	1.018
	  #8	0.6405

The ohms/foot will be 1/1000 of the above values. So, 100 feet of #10
would be about 0.1018 ohms, and a 25A load current would drop about 2.55
volts across the wire irrespective of whether it was solid or stranded.
