Philippine Electrical Code (Subject 4) - Nth

1. The overhead conductors, through which electrical service is supplied, between the last power company pole and the building or other support used for the purpose are called:

• Service entrance

• Service-entrance conductors

• Service drop

• Service-entrance equipment

2. The conductors and equipment for delivering electric energy from the power company to the wiring system of the premises served is called a:

• Service

• Service-entrance conductors

• Service drop

• Service-entrance equipment

3. The conductors between the point of termination of the overhead service drop or underground service lateral and the main disconnecting device in a building are known as:

• Service

• Service conductors

• Service drop

• Service-entrance equipment

4. The necessary equipment connected to the load end of the service conductors to a building or other structure and intended to constitute the main control and cutoff of the supply is known as:

• Service entrance

• Service-entrance conductors

• Service drop

• Service equipment

5. The underground conductors through which service is supplied between the power company’s distribution facilities and the first point of their connection to a building or area service facilities located at the building or other support used for the purpose are known as:

• Service clearance

• Service lateral

• Parallel connection

• Weatherhead

6. In a balanced three-phase, 4-wire system, the current in the neutral conductor:

• Is the same as in the other conductors

• Is lower than in the other conductors

• Is higher than in the other conductors

• Will not flow when all loads are exactly balanced

7. On a 240-volt, single-phase, 3-wire system, the neutral conductor will:

• Never carry current even if the other conductors carry current

• Never carry current larger than the difference between the current in the two ungrounded (“hot”) conductors

• Carry current equal to the current between phases

• Carry current equal to one-half the current between phases

8. The unit used to measure current is the:

• Ohm

• Ampere

• Watt

• Coulomb

9. The minimum allowable current rating of 3-wire service-entrance conductors for a one family dwelling is:

• 60 amperes

• 100 amperes

• 125 amperes

• 150 amperes

10. The minimum allowable current rating of 3-wire service-entrance conductors for a one family dwelling with an initial net computed load of 10 kVA or more is:

• 60 amperes

• 100 amperes

• 125 amperes

• 150 amperes
