250 ft. 10/2 Gray Solid CU UF-B W/G Wire

Yes. 10/2 w/Ground. 30amp circuit. 120 volts x 2 conductors plus the ground.

YES

Hmm, Does it have a, "Bare" ground wire?, No, It has a #10AWG, solid Cu, > or, "Copper", ground wire. And that is wrapped in a "lite-wax, imbued", paper cover that is "Inside" the Polyvinylchloride cover which encases all three wires. The paper comes off very easily though as there is a plastic, "Leader Zip", that you may pull to slice the paper open. It is similar to the way the bonding conductor is/was, provided in the old, "BX" type of wire in that it does in fact, "NOT", have a separate, colored, "PVC", or other coating on, "that", particular wire needing to be stripped, with a tool, as the other "2" conductors will. As prepped for termination. Those other two are the "Bonded conductors" which fall under different guidelines in the "NEC". Also, If you look at the manufacturers cover markings? The "W/G", at the end of the code required rating marks? That currently means, "With Ground". Now, "WHY"?, They simply do not write out the fact that these rolls are, "With Ground"?? This?, Only the TOP- "Braniacs", in their, "Marketing Division", Will EVER know! I hope this helps.

Yes it would!
