4 1 INTRODUCTION TO THE FULL IMPACT ASSESSMENT The Full Impact Assessment follows the rationale of the Canadian Electrical Code Ranking Tool (CRT) and provides supporting information to validate the rankings of the CRT. It includes all the questions of the CRT either verbatim or modified. However, the scope of the Full Impact Assessment extends beyond that of the CRT and, therefore, the assessment includes additional questions that may help to substantiate the rankings. The CRT is referenced throughout the Full Impact Assessment. The questions from the CRT are identified in the Full Impact Assessment by numbers in parentheses. Whenever applicable, chapter titles also include references to the relevant sections of the CRT. The Full Impact Assessment follows the sequence of the CRT as closely as possible but, to enhance the analytical function of the document, risk-related and benefits-related questions have not been separated in the Full Impact Assessment. 2 PURPOSE OF THE FULL IMPACT ASSESSMENT The purpose of the Full Impact Assessment is to provide the provinces and territories with an enhanced rationale and detailed assessment of a particular change to the Canadian Electrical Code, Part I (CE Code, Part I). This assessment is submitted for review to provincial and territorial regulatory authorities to aid with their adoption process for the Code. Jurisdictions may decide to conduct further analyses or to hold additional consultations. 3 BACKGROUND OF THE CHANGE When an insulated conductor carries current, the temperature of the conductor increases, and continues to increase, as the conductor's current increases, potentially exceeding the conductor s insulation temperature rating. Rule sets out requirements for methods of controlling or reducing conductor temperature. Rule 4-004(1)(d) and(2)(d) specify wiring methods and correction factors used to ensure that conductor temperatures for conductors in an underground run, directly buried or in a raceway, stay within the operating limits of their insulation. The ampacity Tables in the Code are migrating to raw (calculated) ampacities, which may be limited by various Rules and correction factors in the Code. Tables 1 to 4 have been partially recalculated to reflect this shift. In order to align the existing underground Tables (D8A to D15B) with the rest of the Code, the A Tables were recalculated, making the B Tables unnecessary.* Also, these Tables were originally intended to be limited to unshielded cables rated not more than 5 kv. Rule (1)(d) and (2)(d) and the titles of the Tables have been changed to reflect this limitation. *In the new Tables, the designations A and B refer to copper and aluminum, respectively. Page 3 19/12/2014

5 4 THE NATURE OF THE CHANGE (A) Revise Rule 4-004(1)(d) and (2)(d) as follows: Canadian Electrical Code, Part I Full Impact Assessment Ampacity of wires and cables (see Appendixces B and I) (1) The maximum current that a copper conductor of a given size and insulation is permitted to may carry shall be as follows: (a) no change (b) no change (c) no change (d) single-conductor and 2-, 3-, and 4-conductor cables and single-conductor and 2-, 3-, and 4-conductor metal-armoured and metal-sheathed cables, unshielded and rated not more than 5 kv, in conductor sizes No. 1/0 AWG and larger, installed in accordance with configurations described in Diagrams D8 to D11B4-1 to B4-4 in an underground run, directly buried or in a raceway, as specified in Tables D8A to through D11B D15B or as calculated by the IEEE 835 calculation method; (e). (2) The maximum current that an aluminum conductor of a given size and insulation is permitted to may carry shall be as follows: (a) no change (b) no change (c) no change (d) single-conductor and 2-, 3-, and 4-conductor cables and single-conductor and 2-, 3-, and 4-conductor metal-armoured and metal-sheathed cables, unshielded and rated not more than 5 kv, in conductor sizes No. 1/0 AWG and larger, installed in accordance with configurations described in Diagrams D8 to D11B4-1 to B4-4 in an underground run, directly buried or in a raceway, as specified in Tables D8A to through D11B D15B or as calculated by the IEEE 835 calculation method; (e). (B) Revise the Appendix B Note to Rule 4-004(1)(d) and (2)(d) as follows: Rules 4-004(1)(d) and (2)(d) The ampacities shown in Tables D8A to D11B inclusive and D12A to D15B inclusive have been determined using the Neher-McGrath methodology, calculation method in as applied in IEEE 835, for the cable arrangements shown in Diagrams D8B4-1, D9B4-2, D10B4-3, and D11B4-4. The A tables are applicable where no temperature-sensitive equipment is connected or where such equipment is connected but the load is non-continuous. In cases where the calculated A table value exceeds the corresponding Table 1 or 3 value, the calculated value is replaced by the Table 1 or 3 value. The B tables are applicable where the load is continuous and temperature-sensitive Page 4 19/12/2014

6 equipment is connected. In cases where the calculated B table value exceeds the corresponding Table 1 or 3 value, the calculated value is replaced by the Table 1 or 3 value derated in accordance with Rule (Both derated values, corresponding to equipment marked for 100% of its rating and 80% of its rating respectively, are given in the B tables, when those values are less than the calculated value.) A and B tablestables D8A to D11B are based on 90 C, and the values given are limited as described above. If equipment rated at 75 C, (for example), is connected, then Rule applies may limit the conductor termination ampacity., and the allowable current is limited to the 75 C column of Table 1 or 3, derated in accordance with Rule 8-104, instead of the 90 C limitation that is built into the A and B tables. For stacked arrangements of two single conductors per phase in parallel (one row located vertically over another row), it is recommended that ampacities be obtained from the Detail 5 column of Table D8A or D8B (copper) or Table D8BD9A or D9B (aluminum) for direct buried cables, or from the Detail 2 column of Table D9AD10A or D10B (copper) or Table D9BD11A or D11B (aluminum) for cables in underground raceways.* For single-conductor metal-armoured and metal-sheathed cables in which the sheath, armour, or bonding conductors are bonded at more than one point, the derating factors of Rule apply, unless the ampacity has been determined by detailed calculation according to the method outlined in Items Rule 4-004(1)(e), (1)(f), (2)(e), and (2)(f). It is recommended that ampacities for three single conductors per phase and for five single conductors per phase with spacings, directly buried in the earth, be selected from Table D8A (copper) or D8B or Table D8B (aluminum)d9a or D9B for the installation configurations of Diagram D8B4-1, Detail 5 and Detail 7, respectively. It is recommended that ampacities for three single conductors per phase and for five single conductors per phase installed in separate underground conduits in a single bank be selected from Table D9A (copper)d10a or D10B or Table D9B (aluminum)d11a or D11B for the installation configurations of Diagram D9B4-2, Detail 3 and Detail 4, respectively.* It is recommended that ampacities for three-conductor cables and for three singleconductor cables grouped, directly buried in the earth, be selected from Table D10AD12A or D12B (copper) or Table D10BD13A or D13B (aluminum) for installation configurations of Diagram D10B4-3, and ampacities those for three-conductor cables in separate underground raceways be selected from Table D11AD14A or D14B (copper) or Table D11BD15A or D15B (aluminum) for installation configurations of Diagram D11B4-4. It is recommended that ampacities for seven three-conductor cables in separate Page 5 19/12/2014

7 underground raceways be selected from Table D11AD14A or D14B (copper) or D11BD15A or D15B (aluminum) for installation configurations of Diagram D11B4-4, Detail 8. It is recommended that the ampacities of groups of conductors in twos, and twoconductor cables, be obtained from the ampacity Tables D10A to D11BD12A to D15B inclusive for groups of three conductors, and three-conductor cables, for the appropriate spacings between groups and numbers of conductors in parallel.* The neutral conductor of a three-phase, four4-wire system need not be counted in the determination of ampacities. Underground ampacities for conductor temperatures of 75 C and 60 C respectively may be obtained by multiplying the appropriate ampacity at a 90 C conductor temperature from Tables D8A to D11BD15B by the derating factor (for 75 C) or (for 60 C).* Ampacities for underground installations at ambient earth temperatures other than the assumed values of 20 C may be obtained by multiplying the appropriate underground ampacity obtained from Tables D8A to D11BD15B by the following factor: where T ae = the new ambient temperature.* *Where precisely calculated values are not available..

22 5 PURPOSE/REASON FOR THE CHANGE Canadian Electrical Code, Part I Full Impact Assessment 5.1 What is the issue that the change is intended to address? The Tables have been revised to align with a maximum voltage of 5 kv. The underground ampacity Tables did not line up with Tables 1 to 4 with respect to calculated continuous and non-continuous loads and were organized into two Tables (an A Table and a B Table). This made the application of the Tables open to misinterpretation. Moreover, the installation configurations were found in Appendix B while the ampacity Tables were found in Appendix D. This made it cumbersome to work with them. 5.2 How does the change accomplish the desired results? Like the other ampacity Tables, the Appendix D Tables have been revised to give the ampacity of the conductors used in an underground installation without the correction factors from Rule (calculated loads) being applied to the ampacity ratings. Also, the installation configuration Diagrams have been moved to the Tables that give the ampacity ratings for that underground installation configuration. The format is now similar to the format of the new medium-voltage cable ampacity Tables. 5.3 What are the implications/consequences if action is not taken? The changes made to the layout and organization of the ampacity Tables and installation configuration Diagrams are meant to improve the efficiency of Code implementation. If this change is not made at this time, the application of these requirements will continue to be cumbersome and open to misinterpretation. 6 WHY IS ACTION REQUIRED AT THIS TIME? Action is required at this time to standardize the format for underground installations and medium-voltage installations, thus making the Code more consistent and easier to implement. 7 (14) PREVALENCE OF RULE USE IF ACCEPTED Because this change is mandatory for all underground installations using conductors sized 1/0 AWG and larger, it will be applied very frequently. 8 IMPACT ON KEY STAKEHOLDERS 8.1 (16) Largest type of stakeholder who would benefit Engineers/Designers: The underground ampacity Tables and configuration Diagrams have been reorganized to improve the efficiency of Code implementation. Less time and effort will be required to determine conductor sizes. This group of stakeholders is interested in providing cost-effective and safe designs and installation requirements to Page 21 19/12/2014

23 minimize the risk of injury to personnel, damage to facilities, and insurance and legal costs. As such, engineers/designers will need to receive a communication about the change (e.g., a formal letter from the authority having jurisdiction). 8.2 (24) Largest type of stakeholder who would be negatively affected Trainers: This is a broad group that may include those providing training to other stakeholder groups, such as electrical contractors and installers of equipment as well as repair and maintenance personnel where applicable. Training programs and literature, including electronic content, will need to be updated to include the change. 8.3 (15) Other stakeholders affected on a frequent basis The change will affect a broad range of stakeholder groups, as follows: Electrical contractors: This group of stakeholders is responsible for the application of the Code. As such, they need to be informed about changes to it to help ensure full compliance with its requirements. The updates can be delivered through formal training or through industry literature, depending on current practices in a particular jurisdiction. It is the responsibility of individual contractors to keep themselves informed about changes to the Code. Other standards development organizations (SDOs): All references to the provisions of the Code that are being changed will need to be updated in documents published by other SDOs. Provincial/territorial electrical regulatory authorities: This group of stakeholders is responsible for enforcement of the Code and will, therefore, need to be informed of changes to it. Insurance: Insurance policies contingent on following the Code will need to be updated. Builders: This group will need to be informed of the change because the new requirements will have to be implemented in new construction. Inspectors: This group of stakeholders is accountable for enforcing compliance with the Code and needs, therefore, to stay informed about changes to it. It is the responsibility of a particular province or territory to make the information on Code changes available to electrical inspectors. Depending on the practice in a particular jurisdiction, changes can be communicated through training (provided by the jurisdiction or a third party) or through jurisdiction-specific or national industry literature. 8.4 Is the proposed change limited to a specific group/geographic area? The change will have nationwide application. Page 22 19/12/2014

24 8.5 What is the affected stakeholders readiness to act on the change(s)? Research has not revealed any evidence of the market not being ready to implement this change. 8.6 Recommended stakeholder management strategy Not applicable. 8.7 Communication and implementation plan Not applicable. 9 ANALYSIS OF ANTICIPATED ECONOMIC IMPACT 9.1 (20) The jurisdiction or stakeholder s ability to compete, based on incompatibility with other standards The change should not affect a jurisdiction s competitive position. 9.2 (21) Complexity of implementation (is training required to implement the Rule?) The change can be included as an update in existing training programs. No specific training is recommended to introduce the change. 9.3 (22) Total costs to implement (for example, cost to install, educate, manufacture, inspect, purchase additional product, and of the increased use of electricity) There will be a one-time cost to revise training material for trainers and engineers/designers. There is not expected to be a significant increase in the cost of manufacturing, installation, or inspection. 10 IMPACT ON BUSINESS: LARGE AND SMALL (IF APPLICABLE) Compliance costs: No additional costs are expected to result from compliance with the change. Change of investment: Not applicable. Job creation/job loss: Not applicable. Labour mobility: Not applicable. Impact on import/export of goods: Not applicable. Certification and licensing: Not applicable. Insurance: Not applicable. Page 23 19/12/2014

25 11 WHAT IS THE PRACTICE/EXPERIENCE IN OTHER JURISDICTIONS? 11.1 Are standards consistent with (or lesser/greater than) other jurisdictions? Currently, there are no deviations from this requirement of the national Code in provincial electrical codes. Input from other jurisdictions is pending (23) Conflict with other Ministries or Codes No conflict has been observed Consequences for other Departments/Ministries, e.g., apprentice training Not applicable Consequences for other Codes from other jurisdictions (US, European standards) Not applicable. 12 CONSULTATION PROCESS Representatives from the following groups of stakeholders were involved in the consensus approval of this change as part of CSA Group s standards development process: Note: For details about the standards development process as it applies to the CE Code, Part I, please refer to Appendix C of the Code. Regulatory authorities from various provincial, territorial, and municipal electrical inspection authorities Owners/Operators/Producers from groups with national stature, representing the viewpoints of electrical equipment manufacturers, electrical installation designers and installers, and electrical installation users General interest groups with national stature, representing the viewpoints of (a) fire chiefs; (b) electric utilities; (c) committees responsible for related electrical codes and standards; (d) fire insurers; (e) labour; (f) issuers of building codes; and (g) educators. A regulatory/legislative body may want to hold additional consultations with all or some of these groups within its jurisdiction to clarify issues specific to the jurisdiction. Page 24 19/12/2014
