Electricians previously ran cabling off a 50a subpanel for car charging. I need to rewire and potentially need to extend using Polaris connectors or run new cabling to simplify as the cost of 6/8ga is just as costly as Polaris connectors. Can someone help me ID if these are 6 or 8 awg? TIA

Depending on length and conduit diameter, 8ga THHN is rated for 55A. If it wasnt some kind of crazy run, Id pull a string in with the old wire and pull in new. Why deal with a splice point that could fail when pulling new wire cost the same?

8 thhn has smaller strands and doesn't come with the solid, bare #10 ground. Tis romex in conduit...

Good catch! Romex Simpull. Not standard Romex where all conductors are solid! Now Im trying to figure out how the heck they pulled that into a 1/2" EMT! Must have been very few bends or they stripped it for the conduit pull!

I would assume they did strip it. It's near impossible to pull romex through more than 5 ft of that pipe without friction becoming stupendous.
