Figure 9
Figure 9 illustrates a typical installation of a thermocoupled cutoff. Note that the body of the thermal
cutoff is at the same potential as the connecting circuit; therefore, it must be electrically isolated
from the surface against which the cutoff is mounted. Also note that the thermocouple wire is at
the same potential as the connecting circuit.
CAUTION . . . To avoid a false reading of the unit under test, thermocouple wires must not make
contact with each other except at the temperature sensing junction.
CAUTION . . . Ensure that the thermocouple wire insulation will provide isolation against short-
circuiting and shock hazards.
CAUTION . . . The terminal of the temperature measuring instrument, to which the thermocouple
is attached, will be at the same potential as the connecting circuit wire. This instrument must be
electrically isolated and considerable caution must be exercised in its use, since one of the
thermocouple terminals is frequently grounded to the instrument chassis.
Before using measuring equipment powered directly from standard line voltages, check operation
manuals. Be sure line voltages impressed on the thermocouple wires by the dummy cutoffs will
not cause damage to the instrument.
The more closely the actual operating and ambient conditions can be simulated during test, the
more valid the test results will be. These tests are necessary to empirically include the variable
factors that need to be considered to select the properly rated thermal cutoffs. These factors
include, but are not limited to, the heating effect of the current through the cutoff, adjoining
