Break out the pocket protectors and slide rulers for this one. How much CEMF is acceptable in a lighting circuit? I'm trouble shooting a lighting system thats all track lighting. Recently a section burnt up at the coupling and the track, and it supposed a good quality track. Due to its troubled history, I am looking at every angle.
In my research and testing, I discovered a slight unbalance of 0.15 amps via amp clamping all the conductors in the conduit without the grounding couductor.
Is there a way to quantify the resistance of the circuit that is unbalanced? There are two circuits in the conduit with its own grounded conductor. The circuit that the track failed has no measurble CEMF. The second circuit is the one that is reading 0.15 amps. Being that it is in the same conduit as the ciruit that failed, It will affect it some. The big question is is the affect big enough to be concern about?
Any takers onm this one?
