    Let's say the original installation was made under EE sealed and AHJ approved for construction plans. The GES was designed better than CODE minimum for undisclosed reasons.

    You come in years...

    That's what I'm gathering. The small insulated service drop wire is sized for the B-leg load.

    Is it a 2 or 3 transformer bank? 2 would make it open delta.
  3. Good question. I don't have a section. ...

    Good question. I don't have a section.

    Offhand I'd say the grounded conductor must have an ampacity not less than the calculated load (with continuous load factored 120% if connected to OCPD),...

    I'm not contesting that a 'broken' electrode is not an electrode. What is being contested is the manner/legality in which it becomes broke.

    No Code requirement... but may be viewed as illegal if you have no legitimate reason.


    AFAICT, you'd have to connect or remove them. Code has no provision for abandoning in place.


    As you...

    But it's not the same as removing a ground rod. It's the same as cutting off the top of a ground rod.

    No, that is not what I'm saying.

    In analogy I'm saying you cannot install a plastic fitting in an underground metal water pipe to make it not be an electrode after it already is an electrode.

    Says who? You are most certainly not presenting any compelling evidence or precedence. All you are presenting is conjecture.

    IMO, breaking the ring of a compliant ground ring electrode is no...

    IMO, it would not be acceptable unless you also downsized the panel main breaker to 175A... calculated load permitting.

    Welcome... :thumbsup:

    To state panel main breakers are derated is quite onerous. Except for specific atypical cases, panels seldom supply all continuous loads. They can supply up to 100% of...

    And that would be the case if this were installed incomplete. In this case it was installed complete and can be made complete again.
  14. No, it is still a ring, only a broken ring....

    No, it is still a ring, only a broken ring. Whether broken intentionally or not does not matter IMO. I agree with Roger's assessment.... for it to not be a ring, all the components of the ring must...
  15. I understand. Code says all electrodes that are...

    I understand. Code says all electrodes that are present. So not required if not present.

    The point is that the ground ring is present but will be broken. That is not the same as removing the...

    Every set of conductors between service point and service disconnecting means or other disconnecting means or equipment permitted by exception is a service entrance conductor set... no matter how...

    Key word highlighted.

    That can be likened to disconnecting a ground rod... which is also a violation.

    That'd require AHJ's approval, as it is still removing part of the structure.

    Now if that deck board were hinged, that'd be a different matter... :D
  19. I agree, no additional electrodes are necessary. ...

    I agree, no additional electrodes are necessary. But all existing electrodes are required to be part of the GES. I think the AHJ will say the ground ring must be maintained.
  20. The thing that concerns me is you are stating...

    The thing that concerns me is you are stating this is a building expansion. To me that means the existing ground ring has to be interrupted and extended around the addition. If you don't, either by...

    To use the word juxtapose would be a bit of a stretch. While the origin may have been intended that way, its use through the centuries has made it mean something significantly different {place or...

    Interposed enclosures do not exist at or beyond service termini (i.e. utility transformer and service disconnecting means).

    Placed or inserted between service raceway runs or cable with armor runs.

    For example, a typical in-line meter can is interposed in a service entrance riser raceway.

    Correct. Extension grade has a lower operating ambient temperature rating but will pass a signal coming from a higher temperature ambient.
