The CT's plugged into the device are simply regular audio cables. The CT's can be extended using normal audio extension cables (mono or stereo will work fine). 3.5mm extensions for the 200A CT's, 2.5mm extensions for the 50A CT's. We generally recommend keeping the sensor extensions < 20 feet however since signal strength can degrade over further distances and cause measurement inaccuracy. If needing to monitor circuits > 20 feet away or so, that generally would require a separate Gen 2 at that location to capture circuit usage there.
