How do you bond a subpanel?
Rule #3: In a subpanel, the terminal bar for the equipment ground (commonly known as a ground bus) should be bonded (electrically connected) to the enclosure. The reason for this rule is to provide a path to the service panel and the transformer in case of a ground fault to the subpanel enclosure.Click to see…

Keeping this in consideration, does a sub panel need to be bonded?The neutral and ground MUST NOT be bonded at a sub-panel. They should only be bonded at the main service panel. If you bond them anywhere other than the main service, the neutral return current now has multiple paths, including though your ground wire. The ground bar should be bonded to the case.Also Know, how do you wire a sub panel in a detached garage? Build Your Garage Sub Panel Dig an 18-inch deep trench for the outdoor electrical wire, which you will run from the main panel box to the garage sub panel. Use 1 1/4-inch PVC conduit for a 100-amp sub panel or 1-inch PVC conduit if the sub panel is 50 amps or less. Accordingly, what happens if you bond a sub panel? If we bond the ground wire to the neutral in the sub-panel, current will flow on both the neutral AND on the ground wire. Which means that if you do not keep the ground wires separate from the neutral wires, you will be allowing return currents to flow on the ground wires back to the main panel.Why do you separate grounds and neutrals in a subpanel?The neutral wire carries current. So bonding the neutral to the ground in a subpanel will allow current to flow over the ground wire back to the main electrical panel. So bonding the neutral to the ground in a subpanel will allow current to flow over the ground wire back to the main electrical panel.
