I.m sorry but I do not detect cut strands not to argue (there may be). Why is the insulation cracked??
If a terminal is rated for a maximum size conductor than the installation of a larger conductor is a violation.
Regarding Ryans' post, I would like to inquire if the #6 was installed on a 20 A circuit breaker and if so what type of breaker (MFG) was it??(how well did it fit)??
Voltage drop essentially is a product of current drawn by the load multiplicand by the line resistance. This is pretty straight forward for DC applications . It can be a bit more complicated in AC , but for typical residential applications E drop = I line X R of the conductor, is a decent indicator.
What are your concerns regarding voltage drop??
Those terminals on the breaker appear to have groves for the placement of conductors, I do not wish to guess at the maximum gage on the breaker in the picture but I suspect they are larger than the device is listed for.
If the connected conductors exceed the manufactures marking (usually found on the side of the OCPD) then there is a violation and this installation should be cited so!The terminal screw may not have sufficient length to establish a positive connection and you could have over heating of possibly a glowing contact, this not require an incredible a,amount of current. the result over time could include overheating, melting, deformation of the insulation, (arcing and flash-over) and possibly fire.
But I would still like some more information regarding this installation.
