tankless electric water heater

Just bought an eco smart 8 TWH. The instructions call for a 40 amp double pole breaker and #8 wire. The unit has a #8 wire coming out but my electrician said something about China (where it's made) undersizing their wire so he ran a #6 wire from the 40 amp breaker to a quick disconnect where it meets with the #8. I'm an amateur that knows just enough to be dangerous. Is this alright? Will it damage the unit? Will it pass inspection? Thanks

Larger wire than required is fine.
