Installing the Control Unit
AC Power and Grounding
Because equipment can be located throughout a building, the
National Electrical Code requires that the ground point for the
central office trunk protector be bonded to the AC power ground
as shown in Figure 2–3.
The AC outlet and the single-point ground bar must be properly
grounded as shown in Figure 2–1 and Figure 2–3.
Each power supply in the control unit must be connected to the
single-point ground bar by a #12 AWG or a #14 AWG solid copper
wire. Figures 2–1 and 2–3 show this connection.
This wire run should be as short as possible, preferably within 5 ft.
(152 cm), not to exceed 10 ft. (305 cm). See "Approved Grounds,"
later in this chapter, for more information.
The AC outlet must be connected to the 147A protector with a #12
AWG or a #14 AWG solid copper wire.
