NOTE: GRAML models that have multiple voltages
listed, such as 120/208 or 120/240, have multiple
internal circuits. For example a 120/208 volt unit
utilizes 120 volts for light circuit and 208 volts for
the heat circuit(s). Consult the Electrical Diagram
supplied with the unit for specific information.
CAUTION! Light-equipped strip heaters that require
a circuit breaker 20 amps or larger must be installed
with a remote control enclosure containing a fuse
rated at 20 amps or less for the light circuit.
