Comment: Objective Four - Page 20 - Example Two - Solution Two - 1. "Demand factor, Rule 62-116" should be "Demand factor, Rule 62-118". Rule 62-116 is Ground fault protection After the demand factor of 62-118 is applied the 20 kW hallway electric space heating demand is 17. 5 kW. According to Rule 8-106 3) "whichever is the greater load shall be used in calculating the demand. The 18 kVA air conditioning is the greater load at 100% demand and using the 17.5 kW demand for electric space heating will not accommodate the air conditioning load.

Comment: Based off the answer key saying the answer is plenum I suspect this question is meant to be ask the blower motor not the combuation air blower: 1. The combustion air blower forces air directly into the a) Heat exchanger. b) Plenum. c) Flue. d) Cold air return duct. The following question: 6. What voltage does an intermittent pilot ignition system require? a) 24 Vac b) 24 Vdc c) 120 Vac d) A very high stepped-up voltage Lists (d) as the answer but the information about intermittent pilot ignition systems early in the module says "Intermittent pilot ignition systems (IP) may utilize either spark ignition or hot surface ignition to light a pilot burner." These two options use different voltages. Question should be more specific about what type of IP is used.

Comment: Self Test Question number 3 has the wrong answer labeled in the answer guide. it should be C for No. 6 AWG but the answer key states its B. No4 Awg I would advise that you send these modules to an independent 3rd party to go through and verify that all of the information contained in all of the modules are correct as it seems on average there are 2 errors at least per module. Also this is the 21st century can we act like it and update the information to be more current. Its silly to pay for these modules and be given an error riddled outdated document.

Comment: Third Paragraph : Original Statement : Because the auxiliary winding is constructed of larger diameter wire and additional turns it provides a substantial magnetic field of its own. New Recommended Statement: When comparing the small wire-size and low number of turns of the split-phase motors start-winding; the two-value capacitor motor's auxiliary-winding is constructed of additional turns of larger sized wire, providing this motor a much stronger overall magnetic effect.

Comment: On page #11 the modules states "A power factor between 85% and 90% is usually considered to be a good power factor. It is not often economically sound to correct the power factor beyond 90% due to the larger size of capacitors required." I feel that this is a misleading statement as at the start of the objective on page #10 it says "Generally, a power factor below 0.9 results in higher charges." Since the supply authority is going to penalize me if my power factor is below 90%, I am going to target my power factor correction to a value above 90% typically 92-93% or so, not 85 to 90%. Can we please consider this change?

Comment: The answer to self-test question 1 should be b) a controlling device. The answer is backed up on page 19, first paragraph, second sentence. It should be noted that on page 16 in the bullet points near the bottom it says "Connect the control devices to load devices, which respond to those changes, on the right hand side." Using the word "respond" in this sentence can also be thought of as "react" which would change the answer to the above question to d) load device (currently the answer, but in my opinion incorrect). To reduce confusion I would recommend changing this sentence on page 16 to "Connect the load devices on the right hand side of the schematic." The details about load devices are already correctly written in the load device section.

Comment: Top paragraph CEC should read CE Code Figure 22 this photo identifies 10 V terminals as low voltage and not extra-low and the other connection wires that are likely 120 V as high voltage when as in Section 0 of the CE Code these would be low voltage.

Comment: 2 parts to this.

Comment: On this page it is caimed that if all conductors of the same size are used the only table you use is 6. However, I think it should say " the only table you need to use is 6". This is because in appendix b for rule 12-910 it claims that an alternative method may always be to actually calculate with tables 9 and 10. The problem is that nowhere in the code book does it say you must use table 6, it simply says it is permitted. In the field, in a rral world situation, you eould always calculate off tables 9 and 10. 6 is simply a shortcut.

Comment: Figure 1 does not show enough empty spaces for the revisions to 8-108, and requires some grounding and bonding edits as follows: -Remove the two unidentified branch circuits near the bottom of the right hand side of the panel and replace the breakers with empty spaces. -Use the correct ground symbol instead of a triangle. -Move the grounding conductor to a different screw than the brass (orange coloured) screw. -Move the service raceway bonding conductor from the neutral bar to a separate bonding connection.

Comment: Does figure 1 fulfil the requirements of 8-108(1)? I'm wondering if the module can be better written to more clearly explain how tandem-style breakers relate panelboard spaces or branch circuit positions. Tandem-style breakers have become ever more popular with larger homes. Especially for lighting and general receptacle circuits. The 5th sentence on the page states that a tandem-style breaker allows two circuits to be connected to a single space. Does that mean 2 spaces = 4 spaces for overcurrent devices (to me it doesn't). It just seems a little confusing with regards to two-pole spaces and figure 1.

Comment: Question #1 self test Either the answer is wrong, or some justification is needed for the number of spaces required in the panel. The text at the bottom outlines the need for (17 total) circuits for the counter plugs (3 ccts) as well as all the other receptacles, lights, and dedicated circuits listed. The appliance schedule lists 3 - 240V appliances which each need 2 spaces (6 total) The fridge, and washing machine, each require their own ccts based on rule 26-654 a) and b) (2 total) This adds up to 25 circuits so far A microwave and dishwasher are also listed in the appliance schedule but in order for the answer given (28) to be correct there is only one circuit left for us to use and still have the 2 remaining spaces required by code. The dishwasher should generally get it's own circuit because a) most are direct wired and the breaker is used for the disconnect for that appliance and b) based on it's demand it would not be connected to any of the circuits listed. The microwave could be a counter top model and plug into one of the counter receptacles already listed but most microwaves have their own enclosure which would not allow them to be connected to a counter plug, and again because of its demand, it is not feasible to connect it onto a general use receptacle circuit. If the location of the microwave was given as a counter top model the answer given could be correct but this is such a rare occurrence in new construction that it needs to be stated. There is not code that specifically states that the dishwasher and microwave need their own circuits, however when we are given a number of general use receptacle circuits already accounted for we have no idea what the loading of those circuits is, and therefore adding 11.7A or 13.3A to one of those circuits could easily overload them, it also would not be feasible to put them together on a circuit unless you either interlocked them so you couldn't wash dishes and microwave at the same time, or connected them to a 30A circuit which would again be unrealistic.

Pg33: The answer is calculating the EV demand towards the service and main feeder conductors (as would be used in objective 4). T-38 is only used when calculating the service and main feeder conductors. The calculation should add all EV loads at 100%. 10 x 4000w.
