agreement. Contact the NSTAR New Customer Connect Tech
Center for details on the electric line extension policies.
Developers interested in an underground distribution system in
a commercial project should contact the NSTAR New
Customer Connect Tech Center at least one (1) year before the
desired service date.
Developers in the South district should refer to the following manuals:
Underground Distribution System Specification 4-0385 (UDS)
and Commercial Underground Distribution System
Specification 1-0796 (CUDS) for more details.
Residential:
A developer may apply for an underground line extension to
service a residential real estate development. Upon
completion of the installation, all non-electric facilities
installed by the customer in the future public way will be
transferred to NSTAR for ownership and maintenance. In
certain cases in the South districts where the customer installs
conduit on private property to be used for primary cable and
that conduit will always be accessible to NSTAR crews,
ownership of that conduit will also be transferred to NSTAR.
Transfer of ownership is subject to inspections and/or tests as
required and approved by NSTAR.
In the South districts, the developer may construct an
underground line extension, including the electric facilities per
NSTAR specifications using an NSTAR approved contractor
and transfer these facilities to NSTAR for ownership and
maintenance. The underground service cable from the
customer’s property line to the service entrance shall be
owned and maintained by the customer.
Commercial:
The developer shall install, own and maintain all underground
non-electric facilities and secondary service systems at the
developer’s expense.
NSTAR will install, own and maintain the primary cable and
transformers, when such facilities are required or in the South
districts the developer may construct an underground line
extension per NSTAR specifications and transfer the primary
cable system to NSTAR for ownership and maintenance.
Transfer of ownership is subject to inspections and/or tests as
required and approved by NSTAR.
423. Underground Secondary Service from NSTAR
Overhead Lines
The entire expense of supplying the underground service
conductors from the point of termination on the pole to the
customer’s building or structure, including installation of a
handhole at the property line, shall be borne by the customer.
The customer shall own and maintain the underground service
from the property line or handhole to the building. NSTAR
will assume ownership and maintenance responsibility from the
pole to the handhole for residential services. NSTAR will make
the final connections to its facilities after approval is received
from the authority having jurisdiction for the customer-owned
portion of the service. Some services will require a junction
box. Contact the NSTAR New Customer Connect Tech Center
for additional details. (See Sketches 6A and 6B)
When more than one underground service is anticipated,
NSTAR will provide the oversized wire to be installed from the
handhole to the pole. Contact the NSTAR New Customer
Connect Tech Center for additional details.
