In a dwelling living room, general-purpose receptacles must be placed so that no point measured horizontally along the floor line of any wall space is farther than what distance from a receptacle?

1. A6 ftĐúng
2. B10 ft
3. C8 ft
4. D12 ft

Vì sao: Section 210.52(A) requires receptacles so no point along the wall line is more than 6 ft from an outlet, which effectively caps spacing at 12 ft. This lets any 6-ft appliance cord reach an outlet without an extension cord. 8, 10, and 12 ft each exceed the 6-ft reach the rule protects.2023 NEC §210.52(A)

Using NEC Table 430.250, what is the full-load current (FLC) of a 10 HP, three-phase, 460-volt squirrel-cage motor?

1. A11 A
2. B14 AĐúng
3. C21 A
4. D28 A

Vì sao: NEC Table 430.250 lists 14 A for a 10 HP 460 V three-phase motor; these table values (not nameplate amps) are used for conductor and overcurrent sizing. 28 A is the 230 V value, 21 A is a 15 HP motor, and 11 A is 7.5 HP at 460 V.2023 NEC Table 430.250
