Hi Gents,

We will convert our shop voltage from 120v to 220v.We will replace the old transformer 75KVA-480v (208/120 V) by new one (400/230 V). The question is can I use the existed panel boards (see the information
below) or not?

Hello and welcome, but where are you located? Please note this is a UK forum and members will not be familiar with the gear or distribution systems shown in your pictures. However, your proposal appears to be to connect a 400 volt supply to equipment labelled by its manufacturer for 240 volts, so I think the answer will be NO.

I would suggest you get a local licensed electrician to look and confirm the answer is NO, as from this side of the pond (This is a UK forum, and you are in Canada or America) it does look like you are wanting to connect a 400v supply to a panel that is only rated for 240v.
