Bus Splicing
Power Bus
1. The power and ground bus splice kit can be found in a package mounted
to the front of the shipping skid.
2. See Access to the Power Bus on page 17 for standard enclosure and Access
to the Power Bus on page 32 for ArcShield™ enclosure.
3. For a 1200 A power bus, assemble the splice bars as shown in Figure 29 on
page 40 . Tighten the nuts to 45 lb•ft (61 N•m).
For a 2000 A power bus, assemble the splice bars as shown in Figure 30
on page 40 . Tighten the nuts to 45 lb•ft (61 N•m).
For a 3000 A power bus, assemble the splice bars as shown in Figure 31 on
page 40 . Tighten the nuts to 45 lb•ft (61 N•m)
ATTENTION: This procedure requires contact with medium voltage
components. To avoid shock hazards, lock out incoming power
before working on the equipment (See Power Lock-out Procedure on
page 49 ). Verify with a hot stick or appropriate voltage measuring
device that all circuits are voltage free. Failure to do so may result in
severe burns, injury, or death.
IMPORTANT
Verify that the structure series numbers on the splice kit
package match the structure series number found on the
cabinet nameplate (See Starter Identification on page 9
for details regarding the nameplate).
IMPORTANT
Attach the bus links to the cabinet on the left side first - as
viewed from the front of the unit.
IMPORTANT
Always place the bus clamps on the rear side of each main
horizontal bus or splice bar, as viewed from the front of
the unit (see Figure 29 , Figure 30 , or Figure 31 ).
