Sub-panel in detached garage fed with a #10 2 wire, no ground. Neutral isolated. Grounding electrode conductor is connected to a ground rod at garage. (With two 10 gauge conductors, which is wrong).
Question- Is there anyway to make this compliant as 120 volt panel without running a new 4-wire feed?
Such as disconnect the two hots at left lug and add a jumper?
Of course the GEC needs to be replaced with a 6 awg.
