Conduit Installation: Conduit should be installed with lock nut and
bushing. Lock nut should be adjusted so that bushing secures properly,
and conduit and bushing extend as little as possible into enclosure.
5. Connections: With the line POWER OFF, remove Terminal Block Cover
and connect leads using the largest stranded wire size possible (#10 to
#3 AWG, stranded) as illustrated in the wiring diagrams. Screw terminal
torque requirements: #10 AWG (35 in.-lbs.), #8 AWG (40 in.-lbs.),
#3 - #6 AWG (45 in.-lbs.).
Connecting wire lengths from the circuit breaker panel to the 57000's
terminal block should be minimal (less than 18" if possible). Power leads
may be connected to L1, L2, and L3 without regard to phase A, B, or C.
Figs. 4 and 5 illustrate two methods for connection lead attachment.
Cat. No. 57000-M3S series provide a disconnect switch which may be
used in the installation. See Method 3, Fig. 6.
In Method 1, Fig. 4, the TVSS Panel provides a feed through connection
between the circuit breaker panel and a load.
NOTE: Maximum wire size is #3 AWG stranded.
This feed through hookup provides the best connection with regard
to surge protection for the dedicated load. This type of connection is
desirable when the branch feeds sensitive loads that need to be protected,
such as a computer room or an area of electronic instrumentation. Note
that protection components are in parallel with any loads.
