Can I tie the neutral and ground together?
Neutral wires are hazardous-live-parts; that is, they are normally current-carrying conductors that carry the same amount of electrical current as our hot wires. Within our electrical codes, neutral wires are treated exactly the same as hot wires: they are insulated and made inaccessible to people. Ground (or Protective Earth) wires are normally non-current-carrying conductors and are designed to be the low-impedance, fault-current path during accidental fault conditions.

When to bond neutral and ground? Should you make neutral-to-ground bonds in electrical panels?
If your electrical panel is a subpanel, then NO, you do not make a neutral-to-ground connection. If your electrical panel is the first service disconnect point, AND the utility has only provided normally current carrying conductors (phase and neutral wires), then YES, you must make a neutral-to-ground connection.
