INSTALLED POSITION.
ELECTRICAL CONNECTION
The Keating Electric Hot Plate is equipped with a three
wire terminal block for customer connections. Compare
the hot plate terminal connections to the appropriate
wiring diagram for the hot plate (see pages 5-11 Wiring
Diagram) to see if the hot plate is connected three
phase or single phase. All wires, cords, plugs,
receptacles and circuit breakers must be sized
adequately for the full load rating of the griddle as
specified by local codes or, in the absence of local
codes, by the current National Electrical Code
ANSI/NFPA 70 or the Canadian Electrical Code CAN
22.2 as applicable.
The Electric Hot Plate is also equipped with a grounding
lug next to the terminal block. For proper grounding
procedures, see local codes or, in the absence of local
codes, the current National Electrical Code ANSI/NFPA
70 or the Canadian Electrical Code CAN 22.2 as
applicable.
NOTE: The connections to the hot plate can be
changed in the field from three phase to single phase or
from single phase to three phase. This can be done by
simply changing the wiring at the terminal block. To
change the connections for your hot plate, see the
wiring diagram for your griddle on pages 5-11.
NOTE: For hot plates rated at 208-240 volts, the
amperage ratings marked on the nameplates of the
griddles are listed at 240 volts as required by UL.
NOTE: A hole has been punched in the rear of the hot
plate cabinet for a cord or conduit exit. If a cord is used,
the National Electrical Code, UL standards and most
local codes require a bushing or strain relief (not
provided by Keating) to protect the cord.
