Comment: Change the word electromagnetic to ELECTROMOTVE in all the sentences.
(EXCEPT "By far the most common method is electromagnetic induction using generators and alternators.")
Since the module is about producing EMF, change the word Chemical "generatation" to "production"
It should read:
This module describes some methods of producing an electromotive force. By far the most common method is electromagnetic induction using generators and alternators. The chemical production of an electromotive force in cells and batteries is a technology that is making significant improvements. The technology of solar cells, producing an electromotive force from light also is improving and is becoming more significant. Three less commons sources of electromotive force are heat, pressure, and electrostatics.
An electromotive force is the force that:

Comment: This section refers to dwelling units where a fire alarm system is not installed. Smoke detectors are not used where a CPU isn't installed. The students should be made aware that the term smoke detector is totally different then the term smoke alarm.
Page 20 - Connection-Paragraph 2: "When one detector goes into...." should read " when one smoke alarm goes into..."
Page 28 - Questions 15 and 16: change "detectors" to "smoke alarms"
All questions should specify whether a fire alarm system has been installed or not, or the type of dwelling unit. Detached homes and row housing are treated differently than dwelling units in an apartment building requiring a fire alarm system.
Page25, figure 30 - the polarity needs to be reversed on the control panel. When an electrician connects wiring to the panel, the red wire connects to the positive terminal and the black wire to the negative. The panel does the polarity reversal, NOT the installer. Fire alarm signal circuits are drawn in the "ALARM" MODE which is different than control circuits. Page 26 - Class B Signal Circuit - Due to the previous explanation regarding polarity making the diagram appear as if it is in alarm, the explanation of the panel doing the polarity reversal needs to be clarified. Keep in mind we are dealing with first year students
who know nothing about fire alarm systems. Page 29 - Question 22 - Sentence 3 should read" The new smoke alarms to be installed do not...."

Comment: This module could use a modernization. However, in the short-term, small changes can be done in the interim.
There are several typos to correct.
• The word monetary need to be replace by momentary in several location within the document.

2. top of page 10
3. top of page 17
• The word extra is omitted in the term extra-low voltage in several locations within the document
1. top of Page 1
2. top of Page 3
3. top of Page 7
• Figure 12 on page 13 is not a schematic diagram. Figure 15 is a better example of a schematic diagram
• Remove the word “special” from the first two paragraphs on page 14. It is not necessary.
• Sentence 2 at the top of page 3 introduces a term “Isolation sections” with is not necessary.
Should read “Barriers are installed to provide a separation between the line voltage circuits and the extra-low voltage control circuits.”
• The first sentence of the second paragraph of page 3 could be tidied up to read “The operation of extra-low voltage relays differs from standard relays because they are momentarily energized for both on and off functions.
• Replace upper case B from the word Between with lowercase b on the page 3 photograph label.

Comment: The first 2 objectives in this module cover WHMIS. As of December 2018 the new Global Harmonized System was implemented, which has some significant changes compared to the old WHMIS system that is described in the module. I feel that these 2 objectives should be re-written to align the information with the "WHMIS 2018" or GHS that is now being used in industry for training.

Comment: Objective 2
Page 5, Bottom of the page where it says Refer to Rule 8-110 a), b) and c)
· This statement is referring specifically to Rule 8-110. Rule 8-110 no longer refers to second floor or basement. Rewrite to say Plus 100% of any areas above the ground floor used for living purposes and Plus 75% of the area below the ground floor.
· Figure 1 should also be changed to reflect the wording in the CEC.
Page 6, House #1 Basic Load
· Replace the word demand with the word load. The CEC does not refer to demand in this context
Page 6, Balance of the Loads
· Remove the extra spaces at electric clothes dryer - 8 kW and not 8 kW
Page 7 House #1: Total Service Minimum Ampacity
· The CEC no longer refers to minimum ampacity – Rewrite the Title to say House #1: Calculated Load
· The term ampacity is not being used correctly in the first sentence. Rewrite - Using the power formula P = E x I to calculate the minimum ampacity of a service… to Using the power formula P = E x I to find the calculated current of a service…
Page 8, first sentence
· requires a comma between single-phase and 3-wire. This is a single-phase, 3-wire…
Page 8, second statement
· Insert a space between V and =, and remove the spaces the W and / and 240 (make consistent with the rest of the ILM) - 24 000 W / 240 V= 100 A should be 24 000 W/240 V = 100 A
Page 8, third paragraph
· This paragraph misses a lot of information to find the minimum size of the service conductor. 4-004 1) b) must be referenced first. 4-004 22) may be referenced after that. Both subrules must be referenced to determine the minimum size of service conductor. Also, the phrase “minimum size” of service conductor is not used. Rewrite this paragraph with more and correct details.
Page 8, Example
· The term total service demand is not used in the CEC. Use the term calculated load.
· 18900 W / 240 V = 78.75 should be 18 900 W/240 V = 78.75 (note the space between 18 and 900 and no space between W/240)
Page 8, Refer to Rule 4-004 22)
· Use the convention of the CEC when referring to temperature ratings. 75℃ should be 75 ℃ This error occurs throughout this ILM.
· More information is required in this paragraph. The spotty information leaves the student uninformed
· Instead of 89 amps use 89 A for consistency in this ILM
Page 9, second bullet
· The house is fed from a 120/240 V single-phase Edison 3-wire supply. Insert commas in the appropriate places. The house is fed from a 120/240 V, single-phase, Edison 3-wire supply.
Page 9, third bullet
· The dimensions of the dwelling are as follows. Insert colon. The dimensions of the dwelling are as follows:
Page 9, 1 b), c) d), and e).
· The CEC does not use the term demand. Replace all of the terms demand with load as per CEC.
· the basic demand to the basic load
· the range demand to the range load
· the dryer demand to dryer load
· the total calculated demand according to Rule 8-200 1) a) to the total calculated load…
Page 9, f)
· the statement, the minimum ampacity of the service conductors does not ask the correct question regarding the answer in the Objective Two Exercise Answers. The answer talks about the minimum load and not minimum ampacity of service conductors as in the question. Replace the statement in the question to read what is the minimum calculated load.
· Objective 2 leaves a lot of information out. For example there is no reference to 8-106 3) and 62-118. There are no examples with water heating, electric space heating and air conditioning or electric vehicle charging stations with energy management systems. These are necessary to learn how to determine the calculated load of a single dwelling and all of these items should be at least mentioned in this objective.

Comment: Pages 9, 10 and 11 – Layout (format and fonts) of the titles on each page are inconsistent. Make consistent with each other
Page 10 – The title does not reflect what is on the page. The title states second period but Figure 4 is for Third period
Page 13, Question 3 – Rewrite the question to say Which sections are covered in the First Period Electrician Training Profile?
Page 13, Question 3, distractors – There is no such section named Controls and Switching Circuits in the training profile. Rewrite to state d) Switching Circuits, and Relays and Controls
Page 13, Question 3, distractors – The term Canadian Electrical Code does not belong in any of these distractors because the term is not present in the referenced sections of the Electrician Training Profile. Remove Canadian Electrical Code from all of the distractors
Page 13, Question 4 – The question states “With reference to your program outline booklet, how many hours are allocated for the first period on Controls and Switching Circuits?” There is no section named Controls and Switching Circuits. Rewrite to: How many hours are allocated in First Period training for Relays and Controls?
Page 13, Question 4 – Rewrite the distractors in correct numerical order and to reflect the correct answer:
The correct answer is c) 14
Page 22 – Figure 10 is missing. Insert the correct figure
Page 26, Objective Two Exercise Answers, Answer 3 – Rewrite the answer to reflect the improved question. d) Switching Circuits, and Relays and Controls
Page 26, Objective Two Exercise Answers, Answer 4 – Rewrite the answer to reflect the corrected question 4. c) 14

10/11/2019 3:31:33 PM
Comment: The title is incorrect. It should read Service, Feeders and Branch Circuits – Section 8. Note the comma between Service and Feeder
The use of “you” throughout the ILM is an incorrect writing style for a technical ILM. Rewrite the ILM without using this style of writing
Page 1, Objective 2. The CEC no longer uses the term “minimum ampacity of service or feeder conductors…” The CEC now uses the term “calculated load for services and feeders”. The term “minimum ampacity of service conductors” should be replaced with “calculated load”
This module does nothing to address branch circuits supplying 5-15R and 5-20R receptacles or lighting. Considering the title includes branch circuits some of these examples should be included
All references to the term “minimum ampacity of service conductors” should be replaced with “calculated load”
Page 1, Introduction, bottom paragraph is completely misleading. It does not take into account 120 V vs. 240 V
Page 2, Introduction. “If you were to turn on all of the loads in your house at one time, the main circuit breaker would trip because it would be overloaded” is completely incorrect and based on no data. Remove this statement form the ILM
Page 3, Section 8 Terms – “The words demand or demand factor refer to the fact that a circuit or system generally requires less ampacity to operate…” This statement is incorrect because the term ampacity only refers to the current carrying capacity of a conductor and cannot be used to describe a circuit. See CEC definitions – Ampacity.
Page 5 – Single Family Service Calculations - The subtitle is incorrect because the CEC does not refer to a “single family”. This should read - Single Dwelling Service Calculations
Page 5 – Single Family Service Calculations – “Using a calculator and the applicable CEC rules, you can figure out the demand in order to select the size of a service for a single dwelling. This whole sentence should be rewritten but the major errors include using the word demand and the word size. The word demand should be replaced with the term calculated load and the word size should be replaced with word rating.

Comment: Page 33, Answer 2, It should read Subrule 14 and not Subrule 15
Page 33, Answer 4, It should read Subrule 7 and not Subrule 8
Pages 32 and 33 the word subrule should be capitalized when referring to a specific subrule as per CEC format. i.e. “Subrule 2” not “subrule 2”
Throughout the ILM. Use the CEC format when using °C. 90 °C is the correct format. 90°C is not. (Note the space between the number and °C)
