Service entrace conductors run from the service drop to the service box or service panel. True or False? True The service size is determined by the amperage and the voltage ratings of the service. True Is the service drop overhead or underground? Overhead Are service laterals overhead or underground? Underground The drip loop is typically part of the service drop. True or False? False The wire size for the service drop must be the same as the wire size for the service entrance conductors. True or False? False How many wires would you typically find in a 240-volt service drop? 3 What would 4 wires mean? 3-phase electricity What would 2 wires usually mean? 120 volt service List 7 common problems with service drops. 1. Overhead wires too low. 2. Damaged or frayed wires. 3. Trees or vines interfering with wires. 4. Wires too close to doors or windows. 5. Wires not well-secured to the house. 6. Poor connection between service drop and service entrance. 7. Inadequate clearance from roofs. List clearances above ground, swimming pools, and roofs. above roadway--18 ft. above driveway--12 ft. above flat roof--8 to 10 ft. above sloped roof--18 inches away from water in swimming pool--22.5 ft 3 ft. above sloped roof with pitch 4 in 12 above walkway--10 ft. The service entrance conductors run from the _________ to the ___________. service drop to service box All service entrance conductors must be in conduit. True or False? False All service entrance conductors must be attached above roof level. True or False? False The drip loop should be as close to the roof as possible. True or False? False List 10 common problems with service entrance conductors. 1. No drip loop 2. No mast head 3. Mast head not weather tight. 4. Mast or conduit bent. 5. Mast or conduit rusted. 6. Mast rotted (if wood). 7. Mast conduit or cable not well secured. 8. Mast conduit or cable not weather tight. 9. Conduit or cable not well sealed at house/wall penetration. 10. Cable frayed, damaged, or covered by siding. List 4 common areas of water penetration into service entrances. 1. conduit joints 2. mast head 3. roof flashing 4. meter base 5. house entry List 2 functions of the drip loop. 1. Prevents water entry into the conduit or service entrance conductors. 2. Shows that the service drop wires are not straining the splices. Roughly 999 out of 1000 houses have _________ volts available. 240 Roughly 999 out of 1000 houses have __________ service entrance wires. 3 Load calculations are part of a home inspection. False Implications of an undersized service include: a. shock hazard b. fire hazard c. shock and fire hazard d. melting insulation e. nuisance tripping of the main fuses and breakers e. What is the largest single-phase service that you are likely to find in a home? 400 amps What size copper wire would you expect to find on the service entrance for: a. 60-amp service b. 100-amp service c. 200-amp service a. 6 gauge b. 4 gauge c. 2-0 gauge Which of the following is a reliable way to identify the service size? a. the size of the service drop wires b. the distribution panel rating c. the service box rating d. the service entrance conductor e. the service entrance conduit size d. Aluminum is an acceptable service entrance conductor material. True or False? True A fused 200-amp service has two 100-amp fuses in the service box. True or False? False If you can't read the size of the fuses in the service box, you should remove them to try to get a better look. True or False? False Which of the following is a safety issue: a. The main fuses have a lower rating than the service entrance wire. b. The main fuses have a higher rating than the service entrance wire. c. The service box has a higher rating than the service entrance wires. d. The service box has the same rating as the service entrance wires. e. The distribution panel has a larger rating than the service entrance wires. b
