Q.6: Can the cable be bent at a 90° angle?
A.6: Yes, however you must retain a minimal bend radius of 1.5’’ (38 mm). A radius inferior to 1.5” (38 mm) could
cause mechanical breakage.
Q.7: Can two OWC-M heating cable systems be installed on top of one another?
A.7: NEVER. This could create overheating hazards and damage the cables.
Q.8: Can OWC-M concrete heating cables be used outside for snow removal purposes?
A.8: No. OWC-M heating cables are designed as a comfort or heating product for residential interior applica-
tions only.
Q.9: Is it mandatory to have a ground fault circuit-breaker-detector?
R.9: Although Canadian regulations in effect do not require the installation of a ground fault circuit-breaker/
detector, we highly recommend its use for concrete cable applications. In the United States, the use of a ground
fault circuit-breaker/detector is mandated by regulations for all concrete cable installations.
Q.10: Must we have a temperature sensor?
A.10: Yes. This will control the floor surface temperature so it does not exceed the maximum temperature
allowable for the type of floor covering used. Although it is not mandatory to have a temperature sensor when
the system is used with an ambient air thermostat, Ouellet Canada Inc. recommends using a temperature
sensor as well.
Q.11: Can two OWC-M concrete cable systems be connected to the same thermostat?
A.11: Yes, (more if need be) parallel-connected if the total capacity does not exceed that of the thermostat.
Q.12: What happens when the voltage applied is the wrong one?
A.12: A product intended for 240/208V connected to 347V: there will be overheating and then a breakdown will
occur. A product intended for 347V but connected to 240V/208V: will hardly heat. It is therefore very important
to connect the product to the proper voltage.
