Repeated emergency responses at the same address but in different rooms with seemingly different origins seem suspect at best. Would the fuse bypass qualify for termination of electric service because of it’s immediate and obvious danger? It seems likely intentionally done to cause damage. The matter is probably complicated some if he is the only resident.

IIRC, awhile back you mentioned another case of contacting officials with the wallet of an electrical prankster. Could you discuss the seeming pyromaniac with the same person or department? They may be able to give opinions about proceeding where likely illegal activity has occurred. Arson attempts are often given some priority in investigation. Another task may be to discuss your suspicions with other emergency responders that have been in the house and witnessed “the perp” (perpetrator) and ”the scene of the crime.”
