	One is hollow?
	About 0.08"
	Ahemmmm
	(second one is serious....)

	(Assuming the wire is copper....)
	Tubing is 0.25" (is there a standard wall thickness?  Dunno.)
	Wire table gives #6 dia is 0.16....inches.

> How do they compare in current carrying capability?

	DC?
	AC?
	What freq?

	#6, being solid will be a bit better at DC.
	0/25" tube, being of larger dia will be a bit better 
	at AC, more so as the freq goes up.

	Both will be pretty good, nearly equal.

	I'd guess about 60A for the #6 as 'code', but should be
	verified.
	Should carry more than that for non code work...
	(eg Tesla primary wiring...)

	(SOMEone found some handy wire tables on the net.
	But i lost the link...
	(Above is from paper copies...)

	Anyone?
