Rules are simple, when you answer a question cite article number then ask your own multiple choice question and state what year code was used. this thread hopefully will get people practicing going through the code book fast for exam preparation. After a while hopefully we should get a real good practice test going.

(nec 2005)

Which of the following is not a standard breaker or fuse size?
a)30
b)45
c)175
d)275

A)110%
B)90%
C)200%
D)85%

Bkessler · 01-26-2009, 12:39 PM

Answer is B,90 table 430.22e

(2005 nec)

The answer is (b) 1/0 NEC 2005 310.4

In a motor control circuit, with a control transformer primary current rating less than 2 amps, the maximum rating of the overcurrent protection in the primary circuit may be what percentage of the rated current?

a)80%
b)200%
c)110%
d)500%

Bkessler · 01-26-2009, 01:35 PM

That would be D. 500% 430.72 (c)4 (2005) (took 6 minutes. I need practice.!)

High pressure spray washing machines single-phase cord and plug connected rated at 250 volts or less must....
A) have factory installed gfci protection built into the plug or with 12"
of plug.
B) must me plugged into a 20 amp gfci outlet with no other load.
c.). be installed on a gfci breaker.
d) Does not need gfci protection.

Forgot to add a new question 2005 NEC;

The maximum allowable ampacity for #18AWG fixture wire is____amps:

a) 10
b) 12
c) 6
d) 8

Bkessler · 01-26-2009, 05:44 PM

C) six amps, table 402.5

(2005 nec)
In a raceway __awg is the largest size solid conductor you can run.

Answer is a) #10.

310.3 says any conductor #8 and larger must be stranded.

Here's one that was on my J-mans test in 1984:

How many perforations per inch are there in 35 mm film?

a)35
b)5.4
c)1.34
d)16

d)16

Assuming I understand what the question is, I'm going to say c) 1.34, though it is closer to 1.38.
