1 Consult factory for circuit breaker applications.
2 “Time-Delay” fuses are UL class “RK5” .
3 “Normal Operating” (general purpose - no intentional delay) fuses are UL class “K5” (up to and including 60 amp), and UL class “H” ( 65 amp and
above).
4 Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table
310.16. If a flexible cord or cable is used, minimum conductor size may increase. See NEC Table 400.5(A) for flexible cord and cable requirements.
5-5. Connecting Input Power
ST-161 454-A
Tools Needed:
Y Have only qualified persons
make this installation.
Y Disconnect and lockout/tagout
input power before connecting
input conductors for wall recep-
tacle or from unit.
Y Special installation may be
required where gasoline or vola-
tile liquids are present − see NEC
Article 511 or CEC Section 20.
230 Volt Models:
Units come equipped with input power
cord and plug. Wall receptacle is cus-
tomer supplied. To install, select type
and size input and grounding conduc-
tors using Section 5-4. Conductor rating
must comply with national, state, and
local electrical codes.
Install and connect grounding conduc-
tor and input conductors in conduit or
equivalent between wall receptacle and
deenergized line disconnect device.
All Other Models:
Units come equipped with input power
cord for installation into line disconnect
device. Select type and size overcur-
rent protection using Section 5-4.
