Reading Comprehension
Definition
The ability to read written passages, identify main ideas, draw inferences, and determine word meaning from context.
Professional Standards
Professional standards for reading comprehension are established by the relevant certification body and regulatory agencies. Certified professionals must demonstrate competency through examination and maintain credentials through continuing education. Scope of practice is defined by state law and facility policy. Never perform tasks outside your authorized scope.
Assessment Techniques
The ability to read written passages, identify main ideas, draw inferences, and determine word meaning from context. A significant portion of the IBEW aptitude exam. Must read technical passages and answer questions about main ideas and vocabulary.
Relevant formula: Conduit fill is 1 wire=53%, 2 wires=31%, 3+ wires=40% of conduit area. Variables: Wire area from Chapter 9 Table 5, conduit area from Table 4.
Practical Example
Electrical Calculation: Ohms law
Formula: E = I x R
Variables: E (voltage in volts), I (current in amps), R (resistance in ohms)
Example: 120V circuit with 10 ohm load: I = 120/10 = 12A
Regulatory Context
NEC regulatory requirements for reading comprehension:
Article 430 (Motors):
- 430.6: use FLC from Table 430.248/250 not nameplate for conductor/OCP sizing
- 430.22: motor branch circuit conductor = 125% FLC
- 430.52: motor branch circuit OCP inverse time breaker max 250% FLC
Article 334 (Nonmetallic-Sheathed Cable (NM/Romex)):
- Not permitted in commercial buildings over 3 stories
- Must be supported within 12 inches of box, every 4.5 feet
- 334.80: ampacity based on 60 C column of Table 310.16
Overview
The ability to read written passages, identify main ideas, draw inferences, and determine word meaning from context. A significant portion of the IBEW aptitude exam. Must read technical passages and answer questions about main ideas and vocabulary.
Relevant formula: Voltage drop is VD = (2 x K x I x D) / CM. Variables: K=12.9 (copper), I=amps, D=distance(ft), CM=circular mils.
