Accept in Principle
Dennis Alwon, Alwon Electric Inc.
Recommendation: Add new text to read as follows:
Exception: Where extension of the branch circuit does not include any added
outlets or devices.
Often times when changing a service in an older home the
branch circuit conductors do not reach the new location of the panel. The wire
is sometimes just spliced inside the panel to reach the termination points while
other times the circuit may need to be extended a short distance to reach the
new location. Since many areas are inspecting this differently throughout the
country this exception would clarify this section and bring uniformity
Panel Meeting Action: Accept in Principle
Revise the proposed wording to read as follows:
“Exception: AFCI protection shall not be required where the extension of the
existing conductors is not more than 1.8 m (6 ft.) and does not include any
additional outlets or devices.”
The revised wording provides clarity and satisfies the intent
of the submitter.
Number Eligible to Vote: 11
Affirmative: 9 Negative: 1 Abstain: 1
Explanation of Negative:
KING, D.: This Proposal should be rejected. It is the intent of Section
210.12(B) to provide AFCI protection where circuits that are covered by
210.12(A) are “modified.” The submitter has not provided any substantiation to
allow for an exception for AFCI Protection in the branch circuit modification
described in his substantiation. Accepting the proposed exception would greatly
dimish the level of safety currently provided by the requirements of 210.12(B).
Explanation of Abstention:
S.: See my Explanation of Vote on Proposal 2-92.
Comment on Affirmative:
HILBERT, M.: Continue to accept in principle. The issues noted in the
substantiation for this proposal and Proposal 2-11 are often topics of discussion
at IAEI meetings as well as other educational meetings and do need
The proposed language as revised by the panel’s accept in principle action
will go a long way in promoting uniform interpretations. It will clarify that
extending branch circuit conductors within an enclosure for the purposes of
replacing a device or utilization equipment or for extending a branch circuit to
a panelboard being replaced or upgraded does not require an AFCI protective
device to be installed.
Six feet was chosen for branch circuit extensions as it should provide a
sufficient length for most applications where an existing panel is being
relocated out of a clothes closet or to comply with readily accessible
