- 3-5 Circle the correct answer that completes the following sentence. When service
5 / wires are connceted, is always connected first. a) The neutral, then the hot legs. b) One hot leg to test for shorts, the neutral, then the last hot leg. c)The neutral, then the hot leg on the right side of the meter base. d) None of these are correct.: a) The neutral, then the hot legs.
- 4-1 Circle the correct answer that completes the following sentence. is often used to protect a service where it comes out of the ground to a customer's meter box. a) A type SE cable using a weather resistant sheath. b) A dog. c)A riser or service pipe, sometimes called a guard pipe. d) A guy guard placed over the wire.: c) A riser or service pipe, sometimes called a guard pipe.
- 4-2 True or False. It is possible for voltage to be present at a meter box before residential service is connected to it.: True.
- 4-3 Circle the correct answer. Which of the following is the BEST reason to cover and tamp the UG service cable trench before making connections? a) If the cable terminations are made first, movement or strain on the cable during backfill could put a hazardous strain on the terminations in the meter base. b) Dirt fill helps to cool the cable for the current flow, minimizing resistance. c)The backfill acts as insulation, protecting the public and pets from electrical exposure. d) If the dirt is filled after connections are made, the digging equipment may fall in the trench.: a) If the cable terminations are made first, movement or strain on the cable during backfill could put a hazardous strain on the terminations in the meter base.
- 4-4 Circle the correct answer that completes the following sentence.
7 / c)Check that there is 120 volts from line-to-load on both sides. d) Check the meter switch on the of the meter for continuity.: b) Check that there is isolation between each hot leg terminal and ground.
- 5-3 Circle the correct answer. Which of the following is the BEST action to take if voltmeter tests indicate a load is connected in the house and no one is home? a) If there is a Main outside, open the Main, set the meter, and leave a note for the homeowner about the issue. Never set a meter on a load with no outside Main to open. b) If the meter check shows load is equal on both sides, the load is probably a range, gas water heater, or AC. Set the meter and check the AC. If it comes on, there is no risk. c)Customers know you are coming and are unlikely to leave things on the stove. The load is probably AC or water they need when they get home. Set the meter. d) Leave the meter on the ground with an extra seal, the customer will know how to set the meter.: a) If there is a Main outside, open the Main, set the meter, and leave a note for the homeowner about the issue.
