The neutral carries current during normal operation. The equipment grounding conductor provides a path for ground-fault current so a breaker or fuse can open the circuit. They have different jobs. Start with the definitions in 2020 NEC Article 100 and the grounding and bonding rules in Article 250.

| Conductor | Its job | Where to study |
|---|---|---|
| Grounded conductor | A circuit conductor intentionally connected to ground. The neutral is the grounded conductor in a typical 120/240V dwelling system. | Articles 100 and 200 |
| Equipment grounding conductor (EGC) | Connects equipment metal into the ground-fault current path. It is not the normal return conductor for a load. | 250.118 and 250.122 |
| Grounding electrode conductor (GEC) | Connects the system or equipment to the grounding electrode system, such as ground rods or a concrete-encased electrode. | 250.64 and 250.66 |
A grounded conductor is not always a neutral: a corner-grounded delta system has a grounded phase conductor. Use the complete term in the question. The OSHA definitions also distinguish grounded conductors from equipment grounding conductors.
Does the neutral carry current?
Yes. In a simple 120V line-to-neutral circuit, the hot and neutral carry the same load current. For example, a 6A load has 6A in the hot and 6A in the neutral. Current is not used up by the appliance. Electrical energy is converted into heat, light or mechanical work.
In a properly connected 120/240V split-phase circuit with a shared neutral, opposing linear 120V loads can cancel at the neutral. That does not make a neutral safe to touch or remove. Treat it as a current-carrying circuit conductor.

See CE courses and class datesWhy must neutral and ground stay separate in a subpanel?
For a normal feeder-supplied subpanel, keep the neutral isolated from the enclosure and equipment grounding conductors. Bonding them together again would let normal neutral current take parallel paths through equipment-grounding conductors and metal parts.
The service bonding connection belongs at the service equipment under 250.24 and 250.28. Separately derived systems and qualifying existing installations have their own rules. Do not decide where to bond just because a panel has a main breaker. See our main bonding jumper guide.
Practice question
A 120V appliance draws 6A. Should its equipment grounding conductor normally carry that 6A back to the panel?
No. The neutral carries the load’s return current. The EGC provides the fault-current path. Replacing the neutral with the EGC puts normal load current on a path intended for equipment protection.
Common questions
Can I use a ground wire as a neutral?
No. Do not use an EGC as the load’s neutral. Correct the wiring with the proper circuit conductors.
Is the neutral always white?
White and gray are common grounded-conductor identification colors. Article 200 contains the size-specific marking rules and exceptions. Color alone does not establish a conductor’s voltage or prove it is safe.
Does a ground rod replace the equipment grounding conductor?
No. Earth is not an effective ground-fault current path under 250.4(A)(5). Study EGC sizing separately from grounding electrode conductor sizing.
