Comment: DC voltage ratings. The typical voltage ratings for DC motors and Generators are listed, but should the list have "or" in it rather than "and" IE The typical voltage ratings are 125, 250, or 500 VDC for generators and 90,120,180,240, 500, or 550 VDC for DC motors. There has been some feedback that the way they are written leads the reader to believe a single machine could have multiple voltage ratings. It could also be changed to: The typical maximum voltage ratings are 125, 250, or 500 VDC for generators and 90, 120, 180, 240, 500, or 550 VDC for DC motors. DC motors deliver rated torque and rated speed at rated voltage but can operate at reduced voltage indefinitely at reduced load without harm so the voltages are really maximums.

Comment: Under temperature rise the second paragraph starts out with: "The ambient temperature is the temperature of the cooling medium." This is misleading, the ambient temperature is, by definition, the temperature of the surrounding atmosphere. The cooling medium will also be at that temperature before the machine starts producing any heat, which is where I believe the statement was aiming. I suggest: "The ambient temperature is the temperature of the cooling medium before any heating or cooling effect is imparted from the machine." OR "The ambient temperature is the temperature of the atmosphere around the machine and this will also be the temperature of the cooling medium before the machine begins to produce heat."

Comment: Question 11 in the Objective Two Exercise needs to say "...lagging power factor angle..." to make the answer in the back of the module correct. Higher power factor loads (e.g., resistors) have lower %Vreg, while higher power factor ANGLE loads (e.g., coils) have higher %Vreg. Add "angle" to the question stem OR change the answer to "a) decrease".

Comment: The first bullet point at the top pf page 14 that states the value of current is determined by the resultant voltage (Eresultant) is fundamentally incorrect as well as the formula at the bottom of figure 9 on that same page. This machine at the end of the day is still just a motor and has to follow the principles of Kirchhoffs voltage law. What the modules refers to as Vphase is the applied voltage from the source therefore the voltages Eresultant + Egenerated = Vphase. This is stated in every textbook that describes synchronous motors. This ILM is the only reference that ever makes this statement and that is because it is wrong. This also make all of the phasor diagrams that follow incorrect. The generated voltage will lag Vpahse by the torque angle which will again prove KVL and also aline with every other text out there.

Comment: The second paragraph doesn't make sense, as it says that the rotor of a synchronous motor is different from a rotating field alternator (or induction motor) because the rotor supports the field windings, but a rotating field alternator also has field windings installed on the rotor. The statement is true comparing a synchronous motor rotor to an induction motor, but false when comparing a syncronous motor to a rotating field alternator. In addition the amortisseur windings in a synchronous motor are the same as the dampening windings in an alternator. so this is not a difference either.

Comment: The last paragraph at the bottom of the page says to reverse the motor by "...interchanging the start-winding leads." However, this should be the "auxiliary winding" in a two-value capacitor motor (as per Figure 5 above the paragraph). Change "start-winding" to "auxiliary winding".

Comment: The ILM states that the most common single phase motors are between 1/6 to 3/4 hp. This is seems much more like an opinion than a fact. For students who work primarily in rural areas, agricultural and small commercial operations single phase motors up to 7.5 hp are very common especially in grain operations using aeration and or milling equipment. I agree that in applications where motors of 1 hp or larger are needed three phase motors are preferred, but due to the number of people who have large air compressors, table saws, and other such equipment as mentioned before in their residential garages, or farms the number of these larger single phase motors being used is quite substantial.

Comment: Grounding control transformers references 10-206 subrule (2) for an exception for systems that use less than 1000VA. This is no longer the correct rule, and I do believe with the 2018 update also no longer true. I also believe there is a typo in the first sentence and it meant to read mutual induction transformers.

Comment: Figures 15-19 are supposed to show the circuit from Figure 14 programmed in the five different languages, however there are several errors throughout. First, Figure 15 establishes the addresses for the stop (addr 0), start (addr 1), holding contacts (addr 2), overload contacts (addr 3), coil (addr 30), and lamp (addr 31). However in Figures 16-19, the addresses for the holding contacts and overload contacts have been reversed. Second, In Figures 16-19, the coil address is changed from 30 to 0 and the lamp is dropped completely from the diagrams. Third, the overload contacts are completely missing from the instruction list in Figure 19. My suggested fix would be to correct all diagrams to align the addresses, and to just remove the lamp from Figures 14 and 15.

Comment: Question #6 asks what happens when the air pressure in a dry system drops. There are multiple dry systems, but the two main ones are: A pre action system where there is a monitor to check for air pressure, and water is only available when the FA panel goes into alarm. If this system loses air pressure a supervisory signal is annunciated. There are also systems where there is water available at all times, but air pressure holds the water back (used in sections of a fire alarm system where part of the piping is subject to freezing. In this system the drop in pressure would allow water to flow and therefore cause an alarm. The answer given is that a supervisory condition would occur. However both answers could be true depending on the design of the system. Question #10 is also incorrect as smoke alarms should be mounted on the ceiling or as close to the ceiling as possible, and they must be interconnected within a dwelling unit. Mounted on the wall when possible should not be given as the correct answer.

Comment: There seems to be an issue with question #3. The answer given is to connect the inverter at point B which would only be true if the panel had a main overload device rated at 400A but this is not shown on the diagram so you would be allowing 500A to a 400A rated panel. Conversely: If the fuses in the inverter fused disconnect were 175A, OR the fuses in the main service were 250A then you could connect to point A and since that would put the total available current under 480A (120% of the busbar rating) it would be acceptable as long as the two supplies were connected to opposite ends of the bus bars. Either answer would meet the requirements of rule 64-112 (4)

Comment: Question 7 is incorrect, In order to get the correct answer to the question you apply a 70% de rating factor for sheath currents to the conductor ampacity as if they were installed in free air as per rule 4-008. However in Appendix B it states that the correction factor for direct buried cables must be obtained from the cable manufacturer as it may be more favorable than 70%. Change the question so that we have eliminated the sheath currents like we do in the real world and use the value from table D9A, or make them free air and use table 1 and apply the 70%

Comment: In the ILM it states that the hinges on a splitter should be at the bottom so that the door does not fall on the electricians hands. There is no code that states this. The code rule quoted only states that the label must be legible, and even if that does mean right side up, I investigated some splitters in stock at EECOL in Red Deer and found that of the splitters in stock (we looked at 6 of them) 4 had the label affixed to be right side up with the hinges at the top and 2 had the label affixed so that the hinge was at the bottom. In my personal experience I have heard arguments that the ILM is correct, but in the city of Red Deer, inspectors always wanted the hinges at the top so that if the latch to the splitter is accidentally unhooked gravity will force the door closed rather than open. The information shown in the ILM is therefore opinion not law and should not be included in the curriculum.

Comment: When adding the parking lot receptacles into the main service ampacity calculation the reason that rule 8-202, 3) b) does not apply to the calculated value of the parking receptacles is due to the Standata which is of course only applicable in Alberta. Rather than the statement "Remember that no further demand factor is allowed for the parking lot receptacles" it should be stated that this is because of the Standata. Especially for students who will be writing the Interprovincial Exam there needs to be justification for the statement.

Comment: The correct answer for question 4 in the Self-Test is a 225 A overcurrent device. Change option a) to 225 A and adjust the answer key to match. The correct math as per the ILM is as follows: 30 A x 0.63 = 18.9 -- #14<20A> -- 40 A vs 60 A, pick 40 Ao/c 55 A x 0.89 = 48.95 -- #8<50A> -- 100 A vs 110 A, pick 100 Ao/c 26 A x 1 = 26 -- #10<35A> -- 70 A vs 52 A, pick 50 Ao/c 82 A x 0.95 = 77.9 -- #4<85A> -- 170 A vs 164 A, pick 150 Ao/c 150 Ao/c is the largest, therefore: Feeder o/c = 150 Ao/c + 48.95 A + (26 A x 0.85) + (18.9 A x 0.7) = 234.2 A – 225 Ao/c

Comment: Objective Four Exercise: Question 5. Wet wells shall be classified as what location? For Zone 2 to be the correct answer, the wet well would have to be provided with adequate continuous positive pressure ventilation. The Rule 22-704 is correct. Sewer gas(hydrogen sulphide- H2S) is not only poisonous but also corrosive and flammable; thus without adequate continuous positive pressure ventilation a wet well could be classified as a Zone 1 or Zone 0 location depending on gas concentrations and how often they are present.

Comment: Objective 5 for this module states “Determine the minimum ampacity of the feeder overcurrent device required for a group of motors”; however, the phrase “minimum ampacity” is used incorrectly here. We are always looking for the maximum overcurrent device, not the minimum. This is stated right in the first sentence of Objective 5. Also, as per Section 0, the term “ampacity” is used for conductors not for equipment such as overcurrent devices. This objective should be reworded as “Determine the rating of the feeder overcurrent device required for a group of motors”. This wording matches well with the wording of Objective 3 in the same module.

Comment: The differential compound motor is noted as a motor used when a "nearly constant speed" is required. This is only true when operating at near full load, from no load to full load the overall speed regulation of a shunt motor is better than a differential compound but the speed curve of the differential is almost perfectly flat at near full load. I think this is confusing to students and could be explained better. Adding the differential compound motors speed curve to figure 37 and the torque curve to figure 38 would also be helpful.

Also add from JB to wall greater than 1.2 m. • Objective 1, Example #4 (p.7) – Add to question 1.2 meters from panelboard to area and 1.2 meters at least from area to equipment. Or Change the question to below (from RW 90 conductor) TW 75 wire and Solution should indicate that the ampacity is reduced from the 75o degree column of Table 5A according to insulation: 80 A ÷ 0.75 = 106.6 A. Select a conductor from the 75o degree column of Table 2. A No. 2 AWG would be selected: 115 A x 0.75 = 86.2 A. A No 2 AWG with an allowable ampacity of 86.2 is acceptable for the 80 A load. • Objective 1 Exercise, Q.3 – Add 1.2 meters out of ambient area on either end of the conductor or Change questions to Conductor to (from RW 90) TW 75 Then change answer to #3 AWG. • Objective 2, Example (p. 14) Add based on service OC before Table 16 at bottom of page 14 • Objective 3, (p. 18) 4th line down add underline portion 4-008 1) c) 2) and 4-008 Appendix B • Objective 3 Title for Figure 9 should be changed to underline Figure 9 – Flow chart based on Rules 4-004, 4-006, 4-008 1) 2), and 4-008 Appendix B and Appendix D. • Objective 4, (p.21) Third paragraph down after Voltage Drop.

Comment: Would you please check on the DCF (Table D3) formula and add clarification to the ILM as to whether you use the rated conductor temperature or the Conductor allowable ampacity, based on termination temperature. The Masters course offered by NAIT uses Termination Temperature to determine the conductor ampacity and this makes sense based on rule 4-006. Our ILM uses the 90 deg ampacity based on Table 2, yet gives termination temperature of 75 deg 0
