The hosts won all three singles matches and ended up winning 25 games in five matches while Punjab could only manage to win 19.
Rusedeski, former British number one and world number four, said had he played a close match, things could have been different.
"Unfortunately, Ferrero was too good for me. I put my team behind but the (doubles) players really fought well (to come back). Kevin was again too good. He showed why he is number 16 in the world," Rusedski told reporters after the tie.
"The courts were slow and (ball) heavy. But I don't want to take anything away from Ferrero," Rusedski.
