nVent Thermal Management offers two types of power distribution panels: the nVent RAYCHEM brand HTPG (Heat Tracing Panel Group Control) and HTPI (Heat Tracing Panel Individual Control). These power distribution panels have the option of using ground-fault circuit breakers (30-mA trip level). Per National Electrical Codes and nVent Thermal Management requirements, ground-fault protection must be provided for each heat tracing circuit.
