Electricity
Isolate, test, fix. Then test again.
Three practical exams in one district: the electrician, the lineworker and the qualified worker of NFPA 70E. Every station is scored step by step, like the practical exams the trade uses, and the safety steps are critical.
Touch a live part or skip the test before you touch, and Blocky gets the shock: the station ends right there, the cubes come out charred, and the sheet shows your score and the step that was missing.
Electrician
Safe isolation
Find the circuit, switch off, lock and tag it, then prove it dead: test the tester, test every phase, test the tester again.
Bending conduit
Bend EMT with the hand bender: a 90, an offset over a pipe and a stub-up to the exact measure.
Lights from three places
Wire two three-way switches and a four-way, ground every box and switch the lights from all three places.
Panel
Add a new circuit to an isolated panel: wire size against the breaker, neutral and ground on their bars, torque and label.
Motor starter
Wire the starter with start and stop buttons and its overload, then prove the stop works and the motor turns the right way.
Test and certify
Continuity, insulation and polarity with the right meter, read the values to the inspector and fill in the certificate.
Fault finding with a customer
"The breaker trips when I turn on the kettle": ask, isolate, find the fault, repair it, test it and explain the fix.
Lineworker
Tailboard briefing
Lead the crew talk: hazards, procedure, energy control and protective gear, with the rescue plan named.
Gloves and gear
Air-test the rubber gloves, check their test date, then gloves, sleeves and covers on.
Pole climbing
Climb with gaffs and belt to 32 feet, always hooked, and call "In position".
Hot stick and distance
Open a cutout with the hot stick, calling the line voltage and keeping the minimum approach distance.
Temporary grounds
Test for voltage, then ground end first and line end second, and remove them in reverse order.
Signals to the crane
One signal person guides the operator to set a new pole, with the standard hand signals and the emergency stop.
Pole-top rescue
Your partner is unconscious up the pole: climb, tie them off and lower them in under four minutes.
Electrical safety (NFPA 70E)
Arc flash label
Read the label, call out the category and the boundary, and suit up before you cross it.
Lockout / tagout
Notify, shut down, lock with your own lock, release stored energy and try to start it to verify.
Live-dead-live
Prove the tester on a live source, test dead phase to phase and to ground, and prove the tester live again.
Partner stuck on a live circuit
Cut the power before you touch anyone, call 911 and start CPR.
On the radio
Say it out loud at every step: "Circuit isolated, proven dead", the line voltage and your distance, every reading of the tester.
Questions
What can I practice in the Electricity district?
Three practical exams: the electrician (safe isolation, conduit, lighting, panel, motor starter, testing, fault finding), the lineworker (tailboard, gloves, pole climbing, hot stick, grounds, crane signals, pole-top rescue) and NFPA 70E electrical safety (arc flash label, lockout / tagout, live-dead-live, partner rescue).
How is each station scored?
Step by step, like the practical exams of the trade: every step is checked and a missed critical step ends the station with the score sheet.
Is it based on real exams?
Yes. The stations follow the hands-on tasks of US electrician and lineworker practical exams and the NFPA 70E and OSHA electrical safety rules.
