The straight answer is yes. All sub panels outside of the main building require at least one and sometimes two ground rods, aka grounding electrodes. Subpanels for detached buildings/structures also need a ground wire back to the main building.
How many ground rods are required for panel and subpanel?
grounding electrode (grounding rod). There are four reasons why this grounding method is not acceptable: 1) The primary purpose of a grounding rod is to provide lightning protection. A rod is required for separate buildings with subpanels, but not as a substitute ground fault path for the system.
Is your home in need of a subpanel?
There are plenty of reasons to install a sub-panel in your home, and if you’re remodeling or finishing your basement, you’ll certainly need a dedicated sub-panel to route your basement’s power safely and reliably. With many remodeling projects, you’ll often upgrade lighting and appliances, which may require additional circuits in your breaker.

Does your home need an electrical subpanel?
Subpanels are added to a system for three common reasons: space, convenience, or efficiency. Subpanels are usually used to extend the wiring for multiple branch circuits to a specific area of a home or to a building at some distance away from the main panel. A garage, outbuilding, or a room addition might be a place to put a subpanel.
Does a detached garage need ground rod in sub panel?
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.
Why don't you ground 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.) and back to the main panel. Obvious shock hazard!
Should subpanel 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.
How do you install a ground rod for a subpanel?
1:114:03What you're supposed to do is to ground rods at least six feet apart I did 10 feet just to conserveMoreWhat you're supposed to do is to ground rods at least six feet apart I did 10 feet just to conserve wire.
Does a sub panel need a separate ground?
The biggest difference between a subpanel and a main panel is that the ground and neutral buses on a subpanel have to be separated. 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 high off the ground does a sub panel have to be?
All electrical panels must have a minimum of 36 inches of clearance in front of the panel, 30 inches of clearance across the face of the panel, and a minimum of 78 inches above the floor from the top edge of the panel.
Can ground and neutral be on same bar in 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.
Detached Buildings Sub Panel Grounding Requirements
In this type of subpanel grounding, we recommend that you consult your electrician first. It is an extensive project and often requires a license, so if you don’t have one, you’ll be wise to leave it for the professionals.
Same Building Subpanel Grounding Requirements
Grounding a subpanel in the same property is not hard. All you need to do is double-check a few things first. We have outlined the various requirements that you’d need to uphold.
