1. Under the 2026 NEC Article 100 definition of readily accessible, a disconnect is behind a locked electrical-room door. Everyone who requires ready access has the key and can reach it promptly, without other tools, obstacles or portable ladders. Does the lock alone necessarily disqualify it from being readily accessible?

ANo; because accessibility rules never apply to disconnects
BYes; every disconnect must be reachable by the public
CYes; any door makes equipment inaccessible
No; authorized access can still be readily accessible

Why D is correct

No. The definition permits keys; people requiring ready access must still be able to reach the equipment promptly without other tools, climbing, removing obstacles or using a portable ladder. This evaluates the lock alone, not compliance with every disconnect-location rule.

2. Under 2026 NEC Article 100, a load is expected to operate at its maximum current for three hours or more. How is it classified?

As a continuous load
BAs a noncoincident load
CAs a motor load regardless of equipment type
DAs an intermittent load

Why A is correct

A, a continuous load. The definition depends on how long maximum current is expected to continue. It does not turn the equipment into a motor or establish noncoincident operation. Classification is distinct from the conductor/OCPD sizing calculation; it does not require multiplying every Article 120 load value by 125%.

3. Conductors run from service equipment to a downstream panel whose breakers supply final loads. How is that run classified?

AAs a service drop
As a feeder
CAs utilization equipment
DAs a branch circuit

Why B is correct

A feeder carries power from service or other supply equipment to the final branch-circuit overcurrent devices. The circuits leaving those final devices are branch circuits, so the panel location in the distribution path controls the classification.

4. A disconnect is behind a locked electrical-room door, and everyone requiring ready access carries the key. Under 2026 NEC Article 100, which term addresses reaching it quickly without other tools, climbing over or under obstructions, removing obstacles or using portable ladders?

AWithin sight
BConcealed
CExternally operable
Readily accessible

Where to look it up

https://www.mikeholt.com/newsletters.php?action=display&letterID=3029

Why D is correct

The term is readily accessible. A key is allowed, but the actual access must remain prompt for the people who need it. Visibility, concealment and external operation describe different properties.

5. A one-line diagram shows 42 kA of available fault current at a new switchboard. Which equipment characteristic must be coordinated with that value?

Its interrupting and short-circuit ratings
BIts branch-circuit count only
CIts normal operating temperature for the NEC term and plan condition described
DIts enclosure paint system

Why A is correct

Equipment intended to interrupt fault current needs adequate interrupting rating, and the assembled equipment must withstand the available fault current. Normal load rating alone does not establish fault suitability.

6. A plan notes that display lighting will operate at maximum current for four consecutive hours each business day. Under 2026 NEC Article 100, how is that load classified?

AAs a temporary load
As a continuous load
CAs an intermittent load
DAs a noncoincident load

Where to look it up

https://masterbuildconsulting.com/daily-code-talk/sparky-nec-100-continuous-load-demand-duty/

Why B is correct

B, a continuous load. Four consecutive hours at maximum current exceeds the three-hour threshold. The daily operating schedule does not make it temporary, intermittent or noncoincident.
