  1. The wires connected to the load side of the service disconnect.
  2. The wires from the transformer on the pole to the attachment point.
  3. The wires from the service point to the terminals of the service equipment.
  4. Any of the wires that are of the utility company and not the homeowner.
  5. The service drop conductors that are spliced at the masthead.

If the answer is with regard to Utility Supplier Responsibility

Why would a Home Inspector have to know this ?

#2 (attachment point? whatever that is)
#4 (Any of the wires that are of the utility company and not the homeowner?)
#5

#1. Wires don’t connect to the load side of the service disconnect. Current travels through the disconnect to the bus bar, to the branch circuit breakers to the branch conductors.

#2. Only one wire does that and that’s the neutral. The two 120v service wires connect to the entrance conductors at the splice.

#3. The service point is the splice at the drip loop. The terminals on the service equipment are the lugs on the main bus bar in the service panel. The service entrance conductors run from the splice to the lugs, connecting to the meter en route.

#4. That would be the service drop.

#5. The service drop runs from the conductors or transformer at the utility pole to the service point where it connects to the service entrance conductors.

Exactly, but the choice of answers are a little odd----:stuck_out_tongue:

#3 based on the defintion of Service-Entrance Conductors, Overhead System. Some definitions from Article 100 of the NEC:

Answer is #3

Nice exercise!
