If you cannot measure AC on the cable entering the box, then that suggests that there is a problem upstream or upstream circuit protection has activated. Check the circuit protection at the other end of that cable first.

Sorry, yes, there is a fuse inside on the AC side beyond the relays.

However, no matter the state of this fuse, it's won't affect what you observe on the AC input terminals.
