4-105 Log #3830 NEC-P04 Final Action: Accept
(230.40 Exception No. 4)
_______________________________________________________________
Submitter: James H. Maxfield, Dover, NH
Recommendation: Revise text to read as follows:
Exception No. 4: A Two-family dwellings, or a multifamily dwellings and
multiple occupancy structures shall be permitted to have one set of service-
entrance conductors installed to supply the circuits covered in 210.25.
Substantiation: The current exception only applies to two family and
multifamily dwellings. It would appear that the intent of the exception is to
permit an additional disconnecting means to comply with the minimum
standards of 210.25 where common area branch circuits are installed on
existing two family and multifamily structures.
The current language does not permit the addition of service conductors of
the same voltage to an existing multiple occupancy structure.
For example, an existing multifamily dwelling consisting of six individual
dwelling units which requires the installation of smoke alarms within the
common areas or site illumination of any other common load could use the
current exception to install a ?house panel? to accommodate the new circuits
without performing alterations to an existing code compliant electrical service.
While a multiple occupancy structure which may need to add common area
branch circuits as described in 210.25(B) of the 2008 edition would need to
perform some service alterations to an existing code compliant service to
accommodate the necessary new branch circuits. This could be very
impracticable depending on the size and location of the existing compliant
installation.
Acceptance of this revised language would avoid the need to perform service
alterations to an existing code compliant service of a multiple occupancy
structure.
