2.1
System Description
The system shall be constructed using multiple surge protection modules
utilizing metal oxide varistors (MOVs) which have been tested and matched
to assure surge current sharing. Use of other surge protective devices such
as gas tubes, silicon avalanche diodes, or selenium cells are unacceptable
since the failure of such devices could cause interruption of normal power to
connected loads.

ventilation openings. The cover of the enclosure shall be hinged on the left
side and require a tool for access to internal components. Status monitoring
for the unit must be visible without opening the door. The enclosure
maximum dimensions shall be 30" high, 24" wide and 9" deep.
2.3
Connections
Terminals shall be provided to accommodate wire sizes up to #4 AWG for
units with surge current ratings up to 200 kA. Units over 200 kA shall be
provided with terminals capable of accommodating wire size up to 1/0 AWG.
2.4
Internal Connections and Serviceability
All internal unit connections for components in the suppression path shall be
by way of low impedance copper plates. Surge current diversion modules
shall use bolted connections to the plates to assure low impedance
connections. The system shall be designed for simple change out of any or
all SPD component modules by a qualified electrician. Designs that require
factory service are not acceptable.
