Power Distribution Block (PDB)
Considerations
Ideal for new installations where space for the
power distribution block is more likely to be
available.
Select PDBs with ports capable of accepting 14
AWG AVT sensor leads.
AVT sensor leads must have ferrules applied at
all termination points
SCCR Impact
If a power distribution block (PDB) is added for
VeriSafe installation and not considered in the
SCCR calculations, because the run conductor is
spliced on either end of the PDB, the added PDB
has become part of the power circuit and may
affect the SCCR.
If the power distribution block (PDB) is already
present in the circuit and considered in the
SCCR calculations, there is no impact to the
SCCR rating.
NOTE: The AVT is not part of the power circuit,
as it only acts as a sensing/monitoring device
and does not carry power.
Limitations
If extending the sensor leads, the total length of
the sensor leads plus the sensor lead extensions
must be less than 10ft from the isolation
module to the connection point on the power
conductor (to comply with NEC tap rule)
Space must be available in panel to install the
PDB.
Sensor leads must not be terminated in the
same port.
For applications that require larger than 2/0
AWG conductors, most power distribution
blocks will not have ports sized to accept both
the larger conductor and smaller 14AWG AVT
sensor leads.
