I went on a service call for a customer that owns an apartment building. The tennant said the breaker tripped every time the phone rang, of course when I called it didnt happen. I eventually figgured out what the problem was, lets see who can guess what the problem was.
 
Ultramegabob.....BEFORE you spill the beans...maybe some of the Flat Raters can post their theory s and costs.

TIA.
 
it was one of those digital phones that have the phone libne comming in on the cable and the module that was plugged in was faulty.
 
when I went to take the panel cover off to inspect the breaker and take ampacity readings on the circuit it tripped, and the tennant told me the phone rang again...
 
the phone was located in a room which the person had to turn on a light to enter. the light had a short circuit and it happened to be on the same circuit as the phone. thats my guess
