AC Input and AC Input Ground Connections
Important Safety Instructions
DANGER! Adhere to the “Important Safety Instructions” starting on page 7.
NOTE! Refer to System Application Guide SAG582140000 for recommended wire size, branch circuit
protection, and crimp lugs. Refer also to the SAG for maximum size of wire to connect to the various lug
landing points. Lugs should be crimped per lug manufacturer’s specifications.
• PDSC = AC Input 'Power Distribution Service Cabinet'.
NOTE! Please note that List 35, List 36, List 37, and List 38 Transient Voltage Surge Protector (TVSS)
units designed to be used with solidly grounded electrical systems and are not compatible with High
Resistance Grounding for electrical systems. On a HRG system, L-G voltage rises to the rated line
voltage during a bolted ground fault. At this voltage the TVSS which is expecting to see a Line to
Neutral Voltage would read a Line to Line Voltage across it, which would stress the TVSS and eventually
cause the TVSS to fail.
Wiring Routing Guidelines
Lists 101 and 111 Bays (w/out PDSC): Ten circular openings are provided in the top of each bay for AC input
and AC input grounding conductors. Conduit adapter plates are also furnished. These adapter plates accept
3/4" or 1" inch conduit fittings. Conduit fittings should be installed, and AC input and AC input grounding
conductors should be routed into the cabinet through these openings.
Lists 102 and 112 Bays (with PDSC): Three wiring access plates are secured to the top of the PDSC to
provide a choice of wiring access openings. Choose one of the plates, and remove the two not needed.
Conduit fittings should be installed, and AC input and AC input grounding conductors should be routed into the
cabinet through these openings.
Lists 103 and 113 Bays: Six circular openings are provided in the top of each bay for AC input and AC input
grounding conductors. Conduit adapter plates are also furnished. These adapter plates accept 1.75" inch
conduit fittings. Conduit fittings should be installed, and AC input and AC input grounding conductors should
be routed into the cabinet through these openings.
Lists 104 and 114 Bays: Two circular openings are provided in the top of each bay for AC input and AC input
grounding conductors. Conduit adapter plates are also furnished. These adapter plates accept 1" inch conduit
fittings. Conduit fittings should be installed, and AC input and AC input grounding conductors should be routed
into the cabinet through these openings.
Lists 105 and 115 Bays: Ten circular openings are provided in the top of each bay for AC input and AC input
grounding conductors. Conduit adapter plates are also furnished. These adapter plates accept 3/4" or 1" inch
conduit fittings. Conduit fittings should be installed, and AC input and AC input grounding conductors should
be routed into the cabinet through these openings.
