Can I get the seat in electrical engineering at NIT, Hamirpur? My OBC NCL rank is 234966.

I doubt you will be able to get admission into the branch you desire as your rank is very high. Unless you have an additional quota (Physical Disability) you will not be able to get the seat.

Your chances are less of getting any NITs. But you can get colleges of your state may be government colleges. Try JEE college predictor to get more information and insight about college which you can get on the basis of your rank:- https://www.shiksha.com/b-tech/resources/jee-mains-college-predictor
