Can the size of the ground wire be bigger than the wire size of the current carrying conductors? Example: 4#12 & 1#8 ground in 3/4" conduit. Thank you.

This question came up while designing the secondary side of a 15 KVA transformer, where I referred to Table 250.66 for "Service Ground size".

Huh?It is rare that it is required to be smaller than the main wires in anything 400A and less....
