I have my base system temporarily installed with 4 CT on test circuits. 10 more CT are on order. When the new CTs arrive, I want to move the existing CTs to different ports on IotaWatt. I’ve read in several places that CTs cables should not be unplugged “for any length of time” while on a live wire. Does this mean I have to open the CT before I remove the plug? Or turn off the circuit breaker so there is zero current flow? Or can an active CT be unplugged from IotaWatt “for a short period of time”? 15 sec? for 5 minutes?
I’ve also read that a CT should be shorted if not connected to a load. Does that mean all 3 connectors (Tip, Ring, Sleeve) should be shorted together? Would it be better to solder in a burden resistor (say 20 ohm)? If a resistor is added, which 2 points should it be connected to (Tip, Ring, Sleeve)? I have more that 14 circuits and may clamp CTs on all the circuits and only plug in the ones that are of interest. The plan is to leave the others clamped on a wire but not plugged into IotaWatt.
