Q. How do you size the ground wire when running conductors in parallel?
A. When circuit conductors are run in parallel [310.4], an equipment grounding conductor must be installed with each parallel conductor set and it must be sized in accordance with Table 250.122, based on the rating of the circuit overcurrent device [250.122(F)].
