Safety and safe work practices

Choose the best answer based on what you would do in the field.

1Before replacing a fixture on an existing circuit, what is the best first work sequence? Turn off the wall switch and begin workIdentify the source, deenergize it, apply the required lockout/tagout controls, and verify absence of voltage with appropriate test equipmentRemove the lamps and treat the fixture as safeWear gloves and work carefully while energizedI am not sure yet 2What is the preferred way to confirm that a voltage tester is operating correctly when checking for absence of voltage? Test the circuit once and trust the displayCheck the tester on a known live source, test the circuit, then recheck the tester on a known live sourceTouch the probes together before testingUse only a non-contact testerI am not sure yet 3A breaker trips immediately after a new circuit is energized. What should happen next? Install a larger breakerHold the breaker on to see whether it clearsLeave it deenergized and inspect for a short circuit, ground fault, wiring error, or damaged equipmentReset it repeatedly until it stays onI am not sure yet 4You are asked to work inside energized equipment but have not been trained or authorized for energized work. What is the right response? Proceed if another worker watchesUse insulated hand tools and proceedStop and notify the supervisor so the equipment can be deenergized or the company energized-work procedure can be followed by qualified personnelWork only on one conductor at a timeI am not sure yet 02

Conduit and bending fundamentals

Choose the best answer based on what you would do in the field.

5Using two 30-degree bends, approximately how far apart should the marks be for a 6-inch offset? 6 inches9 inches12 inches18 inchesI am not sure yet 6When laying out a 90-degree stub with a hand bender, where is the starting mark normally placed? At the exact finished stub heightAt the desired stub height minus the take-up/deduct specified for that bender and conduit sizeOne conduit diameter before the finished heightAt half the finished stub heightI am not sure yet 7What is most important for preventing a dogleg in a two-bend offset? Making the second bend steeper than the firstKeeping both bend marks and bends in the same planeHeating the conduit before bendingCutting the conduit long after bendingI am not sure yet 8After cutting EMT, what should be done before conductors are installed? Flatten the cut end with pliersReam/deburr the end and install the proper listed fittingWrap the cut edge with electrical tapeNothing if the cut looks straightI am not sure yet 03

Fixtures and installation

Choose the best answer based on what you would do in the field.

9What is the correct approach to grounding a metal fixture and metal box? The mounting screws alone are always enoughBond the equipment and box using the provided/listed grounding means and follow the installation instructions and adopted codeConnect the grounding conductor to neutralGrounding is unnecessary on lighting circuitsI am not sure yet 10How should a fixture be supported? By its branch-circuit conductorsBy the ceiling tile when the fixture is lightBy an approved box or support method suitable for the fixture and installationBy one drywall screw if it feels secureI am not sure yet 11A newly installed LED fixture flickers. What is the best diagnostic approach? Replace the breaker firstSystematically verify supply voltage, connections, neutral integrity, controls/dimmer compatibility, and the driver or fixtureLeave it energized overnightInstall a higher-wattage lampI am not sure yet 12Before installing a replacement fixture, which information should be confirmed? Only the fixture colorThe fixture voltage, ratings, environment/listing, mounting requirements, and manufacturer instructionsOnly whether the fixture physically fitsOnly the lamp wattageI am not sure yet 04

Troubleshooting and diagnosis

Choose the best answer based on what you would do in the field.

13Several receptacles are dead. What is the most useful first diagnostic path? Replace every receptacleVerify the tester, check the breaker and upstream GFCI protection, then identify the last working and first nonworking pointInstall a larger breakerConnect the circuit to another breaker without testingI am not sure yet 14At a 120-volt receptacle you read about 120 volts hot-to-ground but near 0 volts hot-to-neutral. What fault is most likely? An open neutralA reversed grounding conductorA breaker that is too smallA normal readingI am not sure yet 15A breaker trips instantly every time it is reset. Which condition is most likely? A short circuit or ground faultNormal inrush on every branch circuitA loose cover plateA fixture that is too efficientI am not sure yet 16When should a standard continuity or resistance test be performed? While the circuit is energizedOnly after the circuit is deenergized, verified, and isolated as appropriate for the testOnly when a breaker is trippingIt does not matter whether power is onI am not sure yet 17An intermittent problem cannot be reproduced immediately. What is the strongest next step? Replace random parts until it stopsDocument when it occurs, loads and controls involved, safely inspect likely connections, and test the system methodicallyTell the customer nothing is wrongBypass protective devices temporarilyI am not sure yet 05

Plans and jobsite judgment

Choose the best answer based on what you would do in the field.

18A lighting plan uses a fixture symbol you do not recognize. Where should you look first? The fixture schedule, legend, details, and project specificationsA similar symbol from a different projectThe nearest installed fixtureChoose a fixture that fits the openingI am not sure yet 19Field conditions conflict with the plan. What should happen before the installation is changed? Make the easiest change without documenting itStop that portion of work, verify the conflict, notify the supervisor, and document/resolve it through the project processIgnore the planAsk another trade to decideI am not sure yet 20A wire pull becomes much harder than expected at several bends. What is the best response? Keep adding force until the conductors moveStop and evaluate the path, bend count, conduit condition/fill, setup, pulling method, and lubrication before continuing safelyUse a vehicle to pull the conductorsRemove conductor insulation at the pulling headI am not sure yet Finish

One final field note.
