When emt is used with metal boxes, is a plastic bushing required where the conductors enter the box? My sparky says the bushings are only required for 1″ and larger emt.

We buy box connectors with the bushings already in them. A little more expensive but they insure at least one less skin point.
Showoff :)you use thinwall in the powerhouse ?.

We stopped going to them 6-7 years ago. Even then, all we did was HVAC maintenance, repair and some installation.
We were on sacred ground back then. The I & E shop was very territorial about anyone but them running anything. OK with me. They know their stuff and it got me out of the belly of the beast faster if they did all that.
Mostly they ran rigid. A lot more work, but it stands up better in that enviroment much better than thinwall.
gotcha, we'll talk later be careful today.

bushings can and may be used whenever, however, they are required when using conductors of #4 or larger
