Sizing heat trace cable

Webb18 juli 2000 · Power distribution to the heat trace cable circuit is best supplied through a thermal magnetic style circuit breaker with integral GFI. The GFI usually is set at 30 mA to avoid nuisance tripping at lower temperatures. Size the circuit breaker for 25% more current than you calculate is needed based on the total heat trace cable load. WebbWhen the heat loss from a pipe or tube is higher than the capacity of the heat trace cable - the cable must be spiral-wrapped around the pipe or tube. The "heat loss - cable output" ratio can be calculated as. HR = Qhl / Qt (1) HR = "heat loss - cable output" ratio. Qhl = heat loss from the insulated pipe or tube (W/m, Btu/h ft)
