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.
