Unfortunately there's no set answer for this because it depends on many factors such as the diameter of the pipes, the installation density of the heating cables, the outdoor temperature, the installation of thermal insulation sleeves, etc.
There are too many variables to provide an accurate answer. Even though this product is designed to keep pipes from freezing, it is not designed to thaw pipes. If your pipe has frozen with the heat tape installed and energized, please check the placement of the built-in thermostat and verify that the insulation has been properly installed and waterproofed.
No. Only install pipe heat (heat trace cable) in accessible locations. Do not install this self regulating cable in walls or any place where the cable is hidden. Do not run it through walls, ceilings, or floors. The cable must be installed 10“ away from combustible surfaces, such as wood, and it should not be embedded in insulation or roofing material.
Do not wrap self regulating cable around the pipe in a coiled or spiral fashion, and do not use electric tape to attach it. WarmlyYours recommends attaching the cable in a straight run and to use aluminum or fiberglass tape, pipe straps, or plastic zip ties to attach the cable. Then cover the assembly with fire-resistant insulation and assure it is waterproof. Place electrical heating cable WARNING labels every 10‘, and where the label will be clearly visible.
The GPT-130 displays a number of alarms, beside the ground fault it will also alarm for low current. If you have disconnected the load to trouble shoot a possible ground fault in the heater cable, then you probably have a Low Current Alarm and a very low default ground fault current reading.
You can tell the difference by looking closely at the display, it will tell you what the alarm is for. If you want to clear the low current alarm so you can test the controller then go into the configuration menu and disable the Low Current Alarm.
Remember to re-enable the Low Current Alarm when you are done testing and ready to put the unit back into service.
