Requirements
This section contains:
■ Mains Disconnect, 6-5
■ Power Drop, 6-5
■ Connecting Power to the PDU, 6-8
Mains Disconnect
A mains disconnect — providing over-current and
short-circuit protection — should be provided for the
system. It may be a fused switch or a circuit breaker (see
Figure 6-3 on page 6-6).
If a fused switch is used, it must:
■ Be rated for 30 amps in each phase.
■ Open all line conductors and neutral conductors
where local code applies, but not the protective
earth conductor.
■ Be marked "Mains Disconnect" or the equivalent
in your local language.
■ Be marked with a "|" for the "On" position or "O"
for the "Off" position.
■ Be capable of being locked in the "Off" position,
but not in the "On" position.
■ Be installed as close to the system as possible,
where it can be easily reached by the system
operator.
If a circuit breaker is used, it must meet all of the above
requirements plus:
■ Be rated for a minimum of 10,000 amps
interrupting capacity (AIC) if used on a 200–240
volt circuit, or 14,000 AIC if used on a higher
voltage circuit.
Power Drop
■ A separate power drop should be provided for the
testhead due to its high current requirements.
■ Separate power drops should be provided for
xDSL and POTS bays.
■ Copper wire should be used for the power drop.
■ An electrician must determine the wire size for the
power drop. The wires must be sized to ensure
that the voltage at the system does not drop below
90 percent of nominal (see Calculating the
Minimum Voltage on page 6-6).
■ Convenience outlets should be provided near the
system for external equipment such as
programming stations, extra equipment bays, and
automation equipment. Locate the outlets within
one meter (three feet) of the device. See Chapter 3
to plan the location of convenience outlets.
Convenience outlets should supply 20 amps at
100–120 volts or 10 amps at 200–240 volts.
