AK Electrician common mistakes
AK Electrician · Understand the traps and how to avoid them.
Calculating a branch-circuit or feeder load from memory of a typical dwelling instead of applying the demand factors in the order the Code requires (general lighting, small-appliance, laundry, then appliance/fixed loads, then the largest motor at 25%).
Candidates memorize a final amperage for a familiar house and skip the sequenced calculation, so they cannot adapt when the question changes square footage, range rating, or adds an appliance.
What to do instead
Practice writing the calculation as a numbered ledger every time: list each load, its VA, the demand factor applied, and a running subtotal. Never jump to a total until every line is on the page, and re-check the largest-motor 25% addition separately.
Selecting an overcurrent device from the conductor ampacity alone without checking the termination temperature rating, the 60/75 degree column rule for equipment, and the next-standard-size-up allowance.
The ampacity tables are the most rehearsed part of the exam, so candidates stop at the table value and forget that terminations, continuous-load 125% rules, and the round-up permission all modify the answer.
What to do instead
Build a fixed checklist for every OCPD question: continuous load times 125%, ampacity from the correct temperature column, termination limits, standard-size round-up only when permitted, and conductor protection. Answer only after all five boxes are checked.
Treating grounding and bonding as one topic, so the candidate connects the equipment grounding conductor and the grounded conductor at subpanels or omits the main bonding jumper where required.
The terms sound interchangeable in everyday speech, and the exam deliberately mixes service, subpanel, and separately derived system scenarios to test whether the candidate separates them.
What to do instead
For each question, first label the system type (service, feeder to subpanel, separately derived system) and then state where the neutral-to-ground bond belongs and where it must not appear. Drill the three configurations until the location of the bond is automatic.
Answering box-fill and conduit-fill questions by counting only the obvious current-carrying conductors and ignoring the equipment grounding conductor, device yokes, cable clamps, and the free-conductor allowance.
Candidates picture the box contents rather than applying the volume allowance table item by item, and the count differs depending on whether the box holds a single device or several.
What to do instead
Use a written tally: each conductor by size, each clamp, each yoke, each grounding conductor, then multiply by the table allowance per size and compare to the box volume. Practice with mixed-size conductor examples so the per-size allowances become routine.
Misapplying the receptacle spacing and small-appliance/laundry branch-circuit requirements by measuring from the wrong reference point or forgetting wall spaces broken by doorways and appliances.
The spacing rules are stated in terms of wall space rather than room dimensions, and candidates estimate from room size instead of stepping along the wall.
What to do instead
Sketch the wall line and mark each receptacle, doorway, and fixed appliance, then measure the gaps. Count small-appliance and laundry circuits separately and confirm no other outlets are supplied from them.
Sizing motor branch-circuit conductors and overload protection from the nameplate full-load current instead of the table value, and confusing overload protection with branch-circuit short-circuit and ground-fault protection.
Nameplate current feels authoritative, and the two protective devices look like the same requirement unless the candidate knows that one protects the motor from overheating and the other protects the circuit from faults.
What to do instead
For motor questions, state three numbers before answering: table FLC, conductor ampacity at 125%, and the two separate protective device ratings. Confirm which device the question is asking about before selecting a value.
Applying general-location wiring rules to a classified or special occupancy instead of identifying the class, division or zone, and group first.
The special-location articles reuse familiar wiring methods, so candidates answer from general knowledge and miss the added restrictions on equipment marking, sealing, and wiring method.
What to do instead
Make classification the first line of every special-occupancy answer: class or zone, division, group, and whether the location is inside or outside the classified boundary. Only then choose the wiring method and equipment.
Guessing at Alaska licensing and permit requirements from general trade experience rather than from the statute and regulations, including who may pull permits, supervision ratios, and continuing education or renewal timing.
Most study time goes to technical material, and candidates assume state administrative rules mirror other states or their employer's practice.
What to do instead
Study the Alaska statutes and regulations as a separate subject with its own flash cards covering licensing, permits, inspections, supervision, and renewal. Anchor each card to the specific provision rather than to workplace habit.
Skipping the safety and inspection-administration questions because they seem like common sense, then losing points on clearance, approach-distance, and inspection-sequence details.
These items look easy, so candidates answer quickly from intuition and miss the specific distances, boundaries, and procedural steps the exam tests.
What to do instead
Treat safety and administration as a scored topic: memorize working-clearance distances, approach boundaries, and the inspection sequence, then answer these questions last with the same care as calculations.
Rushing multi-step questions and selecting the first plausible answer without reading the qualifier, such as 'minimum', 'not required', or 'shall be permitted'.
Time pressure and familiarity with the topic cause the candidate to pattern-match a keyword and stop reading before the condition that changes the answer.
What to do instead
Underline the qualifier and the question's final demand before evaluating options, and for calculation items estimate the answer first so a distractor that matches a partial step is rejected. Budget a fixed review pass for flagged items.
