Hi all,
Sadly I have to retake the fault finding section of the AM2 next Monday.
We used a multimeter to determine faults.
There are millions of types of fault, however only 4 types of wiring faults are being tested:
Open Circuit = unambiguous/obvious = no ohm reading.
High Resistance = unambiguous/obvious. =high ohm reading.
Cross Connection and Short Circuit.
I understand from training, that short circuit is a line to line or line neutral phase fault creating a higher resistance in another the circuit.
Cross Connection could be anything Crossed over which could be short circuit.
My question is what does the AM2 understand by cross connection and how is this different from short circuit?
Is this a polarity fault or some fault limited to non powered circuits like the equipotential bonding and data/comms?
All books like Scanlon, kitcher and even lecturers give me vagueness.
Probably over thinking as the feedback stated I got a good number of faults but failed to specify locations. Just want to clear up. Many thanks in advance.
