1) Thank you for the replies
2) Depending upon the local utility, they will route the wires originating from their transformer and install the meter at the pole. Then it is the responsibility of the property owner to have a licensed electrician install a main disconnect, the Service Entrance wires into the house and the main electrical panel. The "loop" that you are referring to are the Service Entrance wires leaving the pole and routing into the house.
3) In more populated areas with smaller lot sizes, most electrical utilities will run their wires all the way from the electrical transformer whether underground or overhead and will terminate their wires onto the customer provided meter socket located at the exterior wall of the home. From that point, it is the property owner's responsibility to have a licensed electrician make the final connections from the meter socket into the main electrical panel.
4) If a panel upgrade was performed, ie, the amperage increased from 60 to 100 amps or from 100 to 200 amps, then yes, the Service Entrance wires or final loop would need to be increased in order to accommodate the higher amperage. Remember, a 100 amp service requires larger wires than a 60 amp service. And a 200 amp service requires larger wires than a 100 amp service. In summary, the larger the service, the larger the Service Entrance wires or loop conductors need to be. Distance is also an issue due to voltage drop on the wires and wire sizes are subject to being increased in size due to this.
5) If the service is overhead, then yes, the home will have an exterior Service Riser pipe (mast) installed on the exterior wall of the home in order to protect the wires and will connect to the wires originating from the pole.
6) I would ask him to have his son provide you and the other recipients of the home a copy of his electrical license and insurance. Most likely, he is not a licensed electrician and may have already or will cause electrical wiring problems. As a beneficiary of the trust, you and any other trust beneficiaries have the right to a properly and safe electrical distribution system throughout the home. I would demand that only a licensed electrical contractor be allowed to perform any electrical work on the property. If the trustee is not willing to hire a licensed professional, I would discuss this with your attorney.
If the home was not wired per the National Electrical Code as well as any local codes and code violations result, this now makes the home unsafe and a potential safety hazard. It also presents a problem when it comes time to sell the home. More than likely, any potential home buyer will hire a state licensed home inspector and electrical code violations are the number 1 item that any licensed home inspector will write up. Once electrical code violations are noted, the potential home buyer will either demand that the electrical be properly fixed at your expense or they will "lowball" on the asking price of the home. You have most likely heard of the term "pay me now or pay me later". This is what typically occurs in the real estate transactions.
Also keep in mind, that many lending institutions are now requiring a home inspection performed by a state licensed home inspector where the loan approval is contingent upon the home inspection. At the lender's discretion, they may or may not approve the potential home buyers mortgage... thus a possible lost opportunity for the seller .
