Electrician's Helper practice test

NYC Electrician's Helper exams (including NYC DCAS Exam 7028 and the CUNY Electrician's Helper Exam 7029) test electrical materials, tools, safety, installation, basic electrical theory, calculations, diagrams and schematics, and written comprehension. This free 20-question practice test helps you build familiarity with the format before the real exam.

Sample Electrician's Helper exam questions with answers

The NYC Electrician's Helper exam tests a mix of trade knowledge and general cognitive skills: reading comprehension of safety and materials-handling policy, basic electrical calculations, diagram and logic reasoning, and situational judgment on the jobsite.

Strong candidates review core electrical theory (Ohm's Law, circuits, wiring) alongside safety procedure — lockout/tagout, tool inspection, and reporting requirements — since both areas are tested and neither substitutes for the other.

Use the sample questions below as a preview of the full practice set. They are independent practice content designed to build familiarity with the exam format, not official NYC DCAS or CUNY material.

ReadingSample question 1

A safety bulletin states: "Before performing work on any electrical panel, the circuit must be de-energized and locked out using an approved lockout device. Only the employee who applied the lock may remove it, except when a supervisor follows the documented lockout-removal procedure for an absent employee." A helper wants to remove a coworker's lock because the coworker went on break and the panel "looks safe." What should the helper do?

Correct answer: Leave the lock in place — only the employee who applied it may remove it, except through the documented procedure

Only the employee who applied the lock may remove it, unless a supervisor follows the documented procedure for an absent employee. "Looking safe" is not a basis for removing someone else's lockout device.

ReadingSample question 2

A materials handling policy states: "Conduit and wire must be stored off the ground on racks to prevent moisture damage. Damaged insulation must be reported to a supervisor before the material is used." A helper finds a spool of wire on the ground with visibly cracked insulation. What is required?

Correct answer: Report the damaged insulation to a supervisor before using it

Damaged insulation must be reported to a supervisor before the material is used — a helper may not decide unilaterally that visible damage is "minor enough" to use.

ReadingSample question 3

A tool-use policy states: "Power tools must be inspected for a damaged cord or missing guard before each use. A tool that fails inspection must be tagged and removed from service immediately." A helper inspects a drill and finds the cord insulation frayed near the plug. What should the helper do?

Correct answer: Tag the drill and remove it from service immediately

A tool that fails inspection — including a frayed cord — must be tagged and removed from service immediately, not patched and used or reported later.

ReadingSample question 4

A jobsite rule states: "Helpers may perform assigned tasks under the direct supervision of a licensed electrician. Helpers may not independently perform work on energized circuits under any circumstance." A licensed electrician is called away and asks a helper to "just finish tightening that energized terminal" before they get back. What should the helper do?

Correct answer: Decline — helpers may not work on energized circuits under any circumstance, regardless of who authorizes it

The rule is absolute: helpers may not independently work on energized circuits under any circumstance, even with a licensed electrician's verbal permission.

ReadingSample question 5

A blueprint-handling policy states: "Field changes to an electrical diagram must be documented on the as-built set and initialed by the supervising electrician before work proceeds past that point." A helper notices the diagram does not match a wall's actual layout and improvises a workaround without telling anyone. Was this consistent with policy?

Correct answer: No — the discrepancy should have been documented on the as-built set and initialed by the supervising electrician first

Field changes must be documented and initialed by the supervising electrician before work proceeds — improvising without documentation or approval violates the stated procedure.
