Why does the neutral and ground have to be separated at the panel?

With ground and neutral bonded, current can travel on both ground and neutral back to the main panel. If the load becomes unbalanced and ground and neutral are bonded, the current will flow through anything bonded to the sub-panel (enclosure, ground wire, piping, etc.) and back to the main panel. Obvious shock hazard!

Why do you tie the neutral and ground together?

Commonly the neutral is grounded (earthed) through a bond between the neutral bar and the earth bar. The connection between neutral and earth allows any phase-to-earth fault to develop enough current flow to “trip” the circuit overcurrent protection device.
