Texas Journeyman Electrician Practice Test

Answer choices

1. A. Reserve emergency capacity for life-safety loads and preserve timing and independence
2. B. Keep the receptacle because any load becomes emergency when connected to the system
3. C. Relabel the circuit optional standby so Article 700 no longer applies
4. D. Add a larger receptacle rating without changing capacity or separation

Wrong-answer review

• B. Keep the receptacle because any load becomes emergency when connected to the system: Connection to emergency wiring does not convert a convenience load into life safety.
• C. Relabel the circuit optional standby so Article 700 no longer applies: A label cannot reclassify a system that actually serves required emergency loads.
• D. Add a larger receptacle rating without changing capacity or separation: Receptacle rating does not correct improper load purpose, capacity, or separation.

Answer choices

1. A. Only conductor color because unequal characteristics do not affect current division
2. B. Match parallel conductors and size parallel EGC separately
3. C. Reduce conductor size below 1/0 so resistance balances automatically
4. D. Increase the overcurrent device until all paths carry equal current

Answer choices

1. A. The forty-foot device because distance is the only element
2. B. The fifty-five-foot device because visibility is the only element
3. C. Either device when a directory identifies its location
4. D. Use a rated disconnect visible from machinery and within 50 feet

Answer choices

1. A. Size conductors for load and terminal limits; use dwelling allowance only if eligible
2. B. Add every branch-breaker handle and size the conductors solely from that total
3. C. Use the largest branch-circuit conductor as the service-conductor size
4. D. Ignore equipment terminal ratings whenever conductor insulation has a higher temperature rating

Answer choices

1. A. 32 amperes, because every load is taken at exactly 100 percent
2. B. 38 amperes, because 24 × 125% plus 8 equals 38 amperes
3. C. 40 amperes, because only the noncontinuous load receives a 125-percent factor
4. D. 48 amperes, because the entire connected load must be multiplied by 150 percent

Answer choices

1. A. Only the utility service disconnect because it controls every building conductor
2. B. Only equipment nameplates because additional source labels create confusion
3. C. A portable cover placed over one module during service
4. D. Use PV disconnects, rapid shutdown, and source markings

Answer choices

1. A. Keep 34 A because the load values were added
2. B. Use 40 A: 125% of 24 A plus 10 A
3. C. Use 42.5 A by applying 125% to the combined load
4. D. Use 55 A because every feeder requires a large reserve

Answer choices

1. A. Use a separate grounding electrode but omit an equipment grounding conductor in the feeder
2. B. Run an EGC with the feeder and isolate the grounded conductor at the building
3. C. Bond the grounded conductor to the building enclosure and omit the building grounding electrode connection
4. D. Install only a grounding wire from the main service; no building disconnect is needed

Answer choices

1. A. Use allowed closet luminaires, remove open lampholders, and maintain clearance
2. B. Keep both luminaires if shelves are temporarily empty
3. C. Reduce lamp wattage because lower heat removes type and clearance requirements
4. D. Add AFCI protection as a substitute for closet luminaire clearance

Answer choices

1. A. Use 45 A: 125% of the 36 A table current
2. B. Keep 40 A because the nameplate value controls
3. C. Use 36 A because motor conductors need no margin
4. D. Use 72 A because motor conductors require twice table current
