250.64(E) Raceways and Enclosures for Grounding Electrode ...
https://www.electricallicenserenewal.com/Electrical-Continuing-Education-Courses/NEC-Content.php?sectionID=866.0
The general rule for ferrous metal raceways and enclosures containing a grounding electrode conductor requires them to be electrically continuous from the point of attachment to cabinets or equipment to the grounding electrode and to be securely fastened to the ground clamp or fitting. In the 2020 NEC, cable armor must now comply with this section.
Grounding and Bonding — Part 1 of 3 | EC&M

Bond all metal raceways and enclosures that contain (or support) service conductors [250.92]. Interestingly, the NEC requires raceways and enclosures that contain feeder or branch conductors to connect to the circuit “equipment grounding conductor” [250.86], which is actually a bonding conductor [Art. 100].

The correct answer is: b) False Part IV of Art. 250 covers the bonding and grounding requirements for enclosures, raceways, and service cable connections. As noted in Sec. 250.86, "Except as permitted by 250.112 (I), metal enclosures and raceways for other than service conductors shall be connected to the equipment grounding conductor."
250.80 Service Raceways and Enclosures.

Now, an isolated metal component can remain ungrounded if it has a minimum cover of 18 in. to all parts of the metal component. A similar change occurred in 250.86 pertaining to isolated metal components used in underground runs of nonmetallic raceways, other than service raceways. Below is a preview of Article 250.
Metal wiremold raceway approved for grounding ...

Check 250.118 (14) which tells us that surface metal raceway that is listed for grounding can be used the the grounding means. As far as I know Wiremold is listed for grounding. It is; I had to call Wiremold up once and ask them because I had to install some of it in a patient care area. Save Reply crazymurph Buy American Joined Aug 18, 2009
How to bond both ends of raceway containing grounding ...
https://diy.stackexchange.com/questions/211443/how-to-bond-both-ends-of-raceway-containing-grounding-electrode-conductors
Ferrous metal raceways and enclosures shall be bonded at each end of the raceway or enclosure to the grounding electrode or grounding electrode conductor to create an electrically parallel path. Nonferrous metal raceways and enclosures shall not be required to be electrically continuous. (2) Methods.
Do All Metal Junction Boxes Need to Be Grounded? | Es & Wick
https://www.eswick.com/do-all-metal-junction-boxes-need-to-be-grounded
The reason all metal junction boxes need to be ground-fault protected is because they act as a conductor when water gets into them. Any amount of moisture inside a metal box can cause serious damage to electronics connected to that circuit. The best way to protect yourself from this risk is by including an integral GFPR in all metal junction boxes.
Grounding a 4 square metal box if not spliced in. | Mike ...

All metal boxes are required to be grounded. If the raceway is metallic and qualifies as an EGC then you can skip connecting a wire type EGC within the raceway to the box if the ungrounded and grounded conductors are not spliced. Are you referring to service raceways? Look at 250.148. Last edited: Oct 3, 2012 don_resqcapt19 Moderator Staff member
