No! A ground rod is not a substitute for the equipment ground. To be safe and correctly installed, the ground must be connected back to the originating power source, this being the transformer.
Can I ground a subpanel with a grounding rod?
Yes, any sub panel outside of the main building requires it’s own ground rod and a ground wire back to the main building.
Does a subpanel in a detached building need a ground rod?
The detached structure is required to have its own Grounding Electrode System (GES) i.e. ground rods. The subpanel in the detached structure will have its grounds and neutrals separated.
Does a 60 amp sub panel need a ground rod?
In the same building or attached building no ground rod is required just hot hot neutral ground, with ground and neutral being isolated from each other in the sub panel.
Does a subpanel need a ground wire from main panel?
Most panels come with a bar joining the two, which is easily removed. Code requires subpanels to have a ground connection that’s independent of the main panel’s.
How do you ground an electrical subpanel?
Quote from the video:
Quote from Youtube video: Together in the neutral bar because in the main panel the neutrals and grounds are bonded together by a bonding strap. When you get to the sub panel they have to be isolated.
Why does a subpanel need 4 wires?
The neutral and ground are not bonded in the subpanel. In this setup if a hot wire coming in contact with the non-current carrying parts of the electrical system, (outlet covers, panel covers etc), the 4th ground conductor will provide a low resistance patch back to the source tripping a breaker.
Can ground and neutral 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.
Why do grounds and neutrals have to be separated in a sub-panel?
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.) and back to the main panel. Obvious shock hazard!
What size ground wire do I need for a 100 amp service?
You start with an 8AWG copper wire
You are correct that for a 100A feeder, the associated ground wire needs to be an 8AWG copper or 6AWG aluminum wire.

Does a pool subpanel need a ground rod?
Jimrahbe. CT, Most residential pool sub-panels do not use a separate ground rod. The equipment pad is considered part of the main house assuming that is where the power is coming from.
Does a sub panel need a neutral?
All single phase 240 volt Sub-Panels MUST have a 4-wire cable feed which must have a separate insulated neutral wire and a separate ground wire, which may be uninsulated.
Can I add a ground bar to panel?
Quote from the video:
Quote from Youtube video: And just tighten it down until it clicks then you'll have a properly installed ground bar install as many ground bars as is necessary. Just make sure that they're not in the way of your wiring.
Can neutral and ground be tied 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.
Do you use a bonding screw on a subpanel?
Quote from the video:
Quote from Youtube video: But in this case. The bonding screw is that green headed screw right there. So that screw just simply threads through the neutral bus.
Should neutral and ground be connected in sub panel?
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.
Can you wire a subpanel with 3 wires?
Another way to wire a subpanel was with a three-wire feed; two hots and a neutral, with grounds and neutrals connected together at the subpanel. In this case, the grounds and neutrals have to be connected together.
