CAUTION: Prior to installation ensure the system configuration and
voltage is equivalent to the JSP unit being installed.
Following all applicable National electrical code standards as well as state and
local codes, connect phase, neutral* and ground to JsP . The 60kA, 80kA and
100kA units come with 36" of #10AWG conductors . each phase conductor is
labeled (Phase A, B or c) . The 120kA, 160kA, 200kA, 240kA, 300kA and 400kA
units come with compression box lugs . The installer must provide the appropriate
conductors . ensure that the conductor lengths are kept as short and straight
as possible . on all high-leg delta systems, the high-leg (208V lN) must be
connected to the Phase B of the sPD . (color coded orange according to Nec) .
*The 3-Wire + Ground Delta JSP does not have a neutral conductor.
