AN2016 Cabinet User Guide
Mount the power transfer pedestal to the same mounting pad as the
AN2016 cabinet, a separate pad, or on a pole. Install the power transfer
pedestal according to the recommendations provided by the manufacturer.
Route the 1¾ inch electrical conduit from the AC end compartment to a
point beyond the mounting pad near the pole location. Follow this
recommendation when you use a pole-mounted power transfer switch,
The top surface of the mounting pad must be approximately 2 inches above
the final grade.
Action
To prepare the cabinet mounting site, follow these instructions:
a. Make sure that the area selected for the mounting pad is firm and level.
Note: If the soil is not firm, compact it.
b. Clear an area for the mounting pad and cable conduits in accordance with
the engineering work prints.
c. Excavate the foundation hole to a depth of 12 to 16 inches.
Build a level base for the mounting pad, use a minimum of six inches (152
mm) of sand or gravel.
Dig a trench to the area where the cable and electrical conduit will rise into
the AN2016 cabinet (see
Excavate the trenches to a depth of 30 inches for a standard installation, and
60 inches for areas where there is heavy frost.
a. If using a separate power transfer pedestal, dig a trench for the electrical
conduit going from the AN2016 cabinet to the power transfer pedestal.
Note: Nortel Networks recommends you use the 10 in. x 17 in. cable
entry box for routing your ac cables (see
"Connecting ac power").
b. If using a pole-mounted AC source, dig a trench for the electrical conduit
from the AN2016 cabinet to the pole.
Place the conduits, cables, ground rod(s), and ground wire(s) as indicated on
the engineering work prints.
Note: At the SPC and termination compartment, place the conduits to hold
the four 4-inch conduits in a 2-by-2 pattern. If required, at the AC
compartment end, place two 4-inch conduits side by side.
Install a ground ring system around the proposed foundation mounting pad
according to local electrical codes (see
Rel 1.0 Standard May 1999
Figure 3-3).
