I have been researching for awhile now and need some general feedback on the topic. The question is for a air handler in the attic, can a form of disconnect means be a plug in outlet or does it need a fuse/non fuse able disconnecting means. Home inspector said it can't be a outlet per NEC CODE. Any help is greatly appreciated. And code reference is a huge help.

IMO unless the furnace is equipped with a factory cord then it must be direct wired. It can be just a snap switch for a gas furnace or a non fused a/c type disconnect would work for 240v units

I thought cord and plug could be used for a means of disconnect regardless if it's field wired.

I believe you will find the manufacturer instruction will not allow it

I appreciate the quick feedback. Anymore code references. It might be me but if feel like home inspectors need a refresher on code rather than what they feel it should be.

The only code reference would be 422.16. If you look at the list and the qualification in(A) I think you will see that the inspector has a good argument besides the 100.3 (B) mentioned by Ken-- he had a typo and had (C)
