Can neutral and ground be on the same bar in main panel?

The answer is never. Grounds and neutrals should only be connected at the last point of disconnect. This would be at main panels only.

Can neutral and ground wires go together?

No, the neutral and ground should never be wired together. This is wrong, and potentially dangerous. When you plug in something in the outlet, the neutral will be live, as it closes the circuit. If the ground is wired to the neutral, the ground of the applicance will also be live.

Why are neutral and ground tied together in main panel?

Without the grounding wire, that misdirected electricity could shock you. At the main service panel, the neutral and grounding wires connect together and to a grounding electrode, such as a metal ground rod, which is there to handle unusual pulses of energy, such as a lightning strike.

Can you touch neutral bar in panel?

You can touch a neutral bus bar assuming the circuit is correctly grounded. The reason this is possible comes down to the amount of voltage in a current. The current passing through to a neutral bus bar will already have been used by the load.

Should neutral and ground be bonded?

Quote from the video:
Quote from Youtube video: So if we were to bond the ground in the neutral. Together at every single one of these panels. Say we have a fault condition at the far end the last panel. We have a ground and a neutral bonded

Why are neutrals and grounds separated in a subpanel?

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.)

Where do you bond ground and neutral?

Neutral wires are usually connected at a neutral bus within panelboards or switchboards, and are “bonded” to earth ground at either the electrical service entrance, or at transformers within the system.
