BIP power-and-ground cable installation
Install BIP power-and-ground cables to provide power from a site power
source or system of ac rectifiers to the breaker interface panel (BIP), and to
ground the Passport 15000 or 20000 to the site ground window.
• “Prerequisites to BIP power-and-ground cable installation” (page 197)
• “BIP power-and-ground cable installation task flow” (page 198)
Prerequisites to BIP power-and-ground cable installation
• Determine the types, ratings, size, length, and current capacity for the
power and ground cables from site planning in 241-1501-205 Passport
15000, 20000 Site Requirements and Preparation Guide.
• Install the power cabling with or without conduit between the source of
power and the BIP according to your local electrical standards. Leave
enough cable slack at each end to accommodate the approximate final
position of the terminal connections. Label both ends of each cable to
indicate the mapping of the power source connection points to the studs
at the rear of the BIP. Map the feeds according to “Prerequisites to
installing dc power input cables” in 241-1501-205 Passport 15000,
20000 Site Requirements and Preparation Guide.
• Record the electrical hookup information as you install the cables for
both your site records and on each junction of a cable. Include such
information as
— the grounding method and the available grounding points for all
hardware that will interwork with the Passport 15000 or 20000 and
therefore share the same ground window
— the type of power source as dc from the site power plant or from a
system of ac rectifiers
— if used, any particulars about the system of ac rectifiers
— the A1, A2, B1, and B2 feed cables relative to the specific BIM
connections
— which upstream breakers or fuses control which feeds at the BIP
— the cable path from the power source to the BIP
— the size and distance of each leg of power cables
