ELECTRICAL CONNECTION INFORMATION
WARNING
Authorized supplier personnel normally
accomplish the connections for the ventilation
system, electric supply, as arranged by the
customer. Following these connections, the
factory-authorized installer can perform the
initial startup of the oven.
Check the oven data plate (Figure 2, item H) before
making any electric supply connections. Electric
supply connections must agree with data on the oven
data plate.
NOTE: The electric supply installation must satisfy the
requirements of the appropriate statutory authority,
such as the National Electrical Code (NEC),
ANSI/NFPA70, (U.S.A.); the Canadian Electrical
Code, CSA C22.2; the Australian Code AG601; or
other applicable regulations.
A fused disconnect switch or a main circuit breaker
(customer furnished) MUST be installed in the electric
supply line for each oven; it is recommended that this
switch/circuit breaker have lockout/tagout capability.
The electric supply connection must meet all national
and local electrical code requirements. Copper is the
recommended material for the electrical supply
conductors.
ELECTRIC SUPPLY REQUIREMENTS
Power requirements for electrically heated ovens are
usually 208 - 240VAC, 3-phase, 4-wire (3 ‘hot’, 1
ground), although ovens built for export can have
power requirements of 380VAC. (These ovens have a
5-wire system.) A 2" (51mm) diameter cutout/hole in
the back of the machinery compartment provides
access for the electrical supply connections. Using
flexible cable(s) for the electrical power supply
conductors requires a 2" (51mm) strain-relief fitting
(not furnished) to enable safe access to the terminal
block from which oven power is distributed.
The supply conductors must be of the size and
material (copper) recommended to provide the current
required; (refer to the data plate for the ampere
specifications). The electric current rating for each
conductor supplying a PS360E-Series Oven must
comply to local and national codes.
Typical specifications for each PS360E/PS360EW-
Series Oven are 208V or 240V, 3-phase, 4-wire, 100-
ampere, 30.0kW for PS360E and 36.0kW for
PS360EW. A PS360E-Series Double Oven installation
would require two 125-ampere service connections,
one for each oven; the power consumption also
doubles for such an installation.
The 208V or 240VAC electrically heated oven uses
two legs of the supplied power to provide 208V or
240VAC power for the oven control circuitry.
