3.2
Examine conditions for compliance with requirements for installation tolerances, power
characteristics and other conditions affecting performance of the SPD device. Do not proceed
until unsatisfactory conditions have been corrected.
INSTALLATION
A.
Install devices at service entrance on load side, with ground lead bonded to service entrance
ground.
B.
Install devices for panelboard and auxiliary panels with conductors or buses between SPD and
points of attachment as short and straight as possible. Do not exceed manufacturer's
recommended lead length. Do not bond neutral and ground.
1.
2.
3.
Comply with manufacturer's written recommendation for conductor and circuit-breaker
size for connecting SPD to distribution system. Match circuit-breaker size to conductor
size. Coordinate with Drawings.
Provide multipole, 30A circuit breaker as a dedicated disconnect for SPD if mounted
exterior to the switchboard or panelboard, unless otherwise indicated.
Where SPD cannot be mounted within 18-inches of the panel, high performance, low
impedance cable as recommended by the manufacturer may be provided to eliminate any
potential degradation of voltage protection.
C.
Device shall be installed without extending manufacturer’s wire lengths.
D.
Externally mounted service entrance SPD shall be installed with less than 5’-0" of lead length
from the panels. Installation of leads shall avoid sharp and unnecessary bends. Where SPD
