I have a 30 amp 3pole Nema 3 disconnect mounted to my air unit. We have a 3/4 gal. stub that adapts to seal tite to feed the disconnect. My crew installed the seal tite connectors in a concentric knock out on the bottom of the disconnect. The maximum allowed for the concentric is 1". If I am using only up to 3/4 do I need a ground bushing on the seal tite connector?
