The Company will make all connections to padmount
transformers.
However, on customer owned cable, the customer
must provide all lugs and associated hardware and install them on
the cable.
For any underground service, splices or taps should be
avoide d. If splices or taps (as permitted in NEC Section 230.33
and 230.46) are required, then they must be in an enclosure, or,
direct buried using a splice "listed" for direct burial and for the
cable type used. Any splices on CMP's side of the meter socket
must be accessible for inspection (by CMP). Note, by choosing
the
appropriate meter socket, splicing for the purpose of
"downsizing" conductors may be avoided (refer to the
"Supplement," paragraph 1.10.5).
906. NON-RESIDENTIAL SECONDARY SERVICES
All underground secondary cable (including transformer
interconnecting cables) and terminal lugs required must be
provided and owned by the customer whether from overhead or
padmount transformer installations. Except as noted in Paragraph
914, “Risers”, cable will be installed by the customer.
Three phase service from a pole mounted three-phase unit
or banked arrangement of transformers may be provided for total
switch(s) capacity not to exceed 1,000 amperes. Note: Overhead
secondary will be limited to two-four conductor (three phase
conductors and one neutral/messenger) cables 336.4 kcmil (or
smaller). Underground secondaries consisting of cables with
conductors 4/0 AWG and smaller shall have no more than four
conductors per phase. Underground secondaries consisting of
cables with conductors larger than 4/0 AWG shall have no more
than two conductors per phase. The owner of the secondary
cables shall provide all terminal lugs and transformer secondary
interconnecting cable and connectors. Cable support and
positioning brackets may be required at the discretion of the
