Q. I’ve meagered out the self-regulating cable and it is clear, but the beaker keeps tripping?
A. Often the cable lengths can be too long and place to high a load on the breaker. Load and length charts from the manufacturer should always be consulted when sizing circuits. For instance, the manufacturers chart for a 5 watt per foot cable installed on a 20-amp208-volt circuit may only allow for a 375-foot-long length of cable. If the cable exceeds the 374’ it will trip the breaker.
