John I have never hardwired these types of items in commercial kitchens.
Usually (hopefully) they are moved for cleaning not to mention the need for a disconnect.
The commercial toasters I have seen are factory fitted with 10 cord, these units have a moving metal belt that brings the toast under the elements.
This could be different in this case but if it comes with a 30 amp cord and you change it out in order to up the OCP I believe you have a UL violation.
If it was UL listed for 30 amp OCP a 35 or 40 amp OCP would be a problem.
