Following all applicable National Electrical Code standards as well as
state and local codes, connect phase, neutral* and ground to
CurrentGuard. The 40kA units come with 36 inches of #10 AWG con-
ductors. Each phase conductor is labeled (Phase A, B or C). The 60kA,
80kA, 100kA, 150kA and 200kA units come with compression box lugs.
The installer must provide the appropiate conductors. Ensure that the
conductor lengths are kept as short and straight as possible. On all
high-leg delta systems, the high-leg (208V L-N) must be connected to
the Phase B of the SPD. (color-coded orange according to NEC)
* The 3-wire plus ground Delta CurrentGuard does not have a neutral conductor.
CAUTION: Prior to installation ensure the system configu-
ration and voltage is equivalent to the CurrentGuard unit
being installed.
