III. ELECTRICAL CONNECTION
INFORMATION FOR PS528-SERIES
OVENS.
WARNING
Authorized supplier personnel normally accom-
plish the connections for the ventilation system,
electric and gas supplies, 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 2-10) before making
any electric supply connections. Electric supply connec-
tions 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 regula-
tions.
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.
IV. ELECTRIC SUPPLY FOR GAS HEATED
OVENS
Power requirements for gas heated ovens are 208 -
240VAC, 1-phase, 3-wire (2 ‘hot’, 1 ground). Electrical
connection is made through a cord and plug. 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 PS528-Series Oven is 1.5A.
