STEP 6 – POWER DISTRIBUTION
Power to the heating cables can be provided directly or through external contactors. For large
jobs where power distribution panels are desired, contact Drexan HeatTracer for design and
delivery.
Single circuit control: Heating cable circuits that do not exceed the current rating of the selected
Controllers can be switched directly.
Group control: If current draw of the system exceeds the switch rating, or if the controller will
activate more than one circuit in group control, an external contactor must be used.
