Neutral is a circuit conductor that normally completes the circuit back to the source. Neutral is usually connected to ground (earth) at the main electrical panel, street drop, or meter, and also at the final step-down transformer of the supply.
Should ground be bonded to neutral?
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 (i.e., 3-phase/4-wire or 1-phase/3-wire).
How do you bond neutral to earth?
Quote from the video:
Quote from Youtube video: Goes through the breaker at the service panel. Through the black conductor out into the field to a load like a say a light bulb. Goes through the light bulb comes back on the neutral.
Do you bond the neutral and ground at the meter?
Meter equipment should never be bonded to both the equipment grounding conductor and the neutral. This practice can create parallel paths for neutral current to flow on the equipment grounding conductor between equipment and service disconnect.
Do you bond neutral and ground in subpanel?
When Should Grounds & Neutrals Be Connected in a SubPanel? The answer is never. Grounds and neutrals should only be connected at the last point of disconnect. This would be at main panels only.
Do subpanels need to be bonded?
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.
Do you have to separate neutral and ground in main panel?
The National Electrical Code (NEC) requirement for separated neutrals and grounding wires in a subpanel and separate neutral and grounding conductors back to the main panel, when both panels are in the same building, dates to the 1999 revision.
Where do you bond your neutral at a service?
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.
