Here's what will happen. When you'llyou activate your relays for the first time, the first one to close will have its contactcontacts welded together by a massive overcurrent. Soon enough, other relays will close and hopefully distribute that current more or less evenly.
When you'llyou deactivate your relays, they will all open except the one with welded contacts. Since it will now be alone under full 64A load, it will soon blow up.
Now you have 31 little relays standin' in a line.
