4.2 Electrical Requirements for the System
Where required, all electrical work for the floor heating cable installation must be done by a qualified,
licensed electrician in accordance with local building and electrical codes and the National Electrical Code
(NEC), especially Article 424, Part IX of the NEC, ANSI/NFPA 70 and Section 62 of the Canadian Electrical
Code (CEC), Part I, as well as any other applicable statutory requirements.
WarmlyYours recommends the following controls and accessories for the TempZone™ Floor Heating Cable:
• nSpiration Series controls feature a Listed Class-A GFCI
and a floor sensor to regulate the actual temperature of the floor
• Non-GFCI circuit breaker
In most installations, a Class-A GFCI is required by national and local codes for protection against ground
leakage currents. A Class-A GFCI is included with the nSpiration Series controls. If not using a WarmlyYours
thermostat, a Class-A GFCI thermostat or circuit breaker may be needed.
The TempZone™ Floor Heating Cable should be connected to a non-GFCI circuit breaker for complete
disconnection on all poles with minimum 0.12 inch disconnection distance.
The thermostat should be installed in a single-gang box, flush with the wall at a height of approximately 5
feet or eye level for easy access and operation. The floor sensor cable and the TempZone™ Floor Heating
Cable cold leads shall be routed to the thermostat in separate UL Listed conduits if conduit is required by local
and national electric codes.
If the floor heating cable load exceeds the 15-amp thermostat power rating, consult WarmlyYours for
information on alternative solutions using master thermostats and power modules.
