CEC 2015 Section CEC 2015 Issue

Definitions of

“Electrical contractor”

“National Building Code of

Canada”

Proposed BC

Amendment

“Electrical contractor” means a licensed electrical contractor, as defined in the Electrical Safety

Regulation;


Canada” means the British

Columbia Building Code and local building bylaws;

Recommendation,

Impacts, and

Rationale

Recommendation:

Adopt Section 0 with amendment to definition of “electrical contractor” and adding definition of


Canada”.

Impacts:

No impacts.

Rationale:

Retain existing definitions for consistency with provincial laws.



2


Proposed BC

Amendment

Subrule 2 ‐ 104(1)

Electrical equipment ratings

All electrical equipment marked with a short ‐ circuit current rating or withstand rating shall have ratings sufficient for the voltage employed and for the fault current that is available at the terminals.

Delete subrule 2 ‐ 104(1).

Recommendation,

Impacts, and

Rationale

Recommendation:

Adopt Section 2 except for subrule 2 ‐ 104(1).

Impact:

None.

This was a newly introduced rule in the

2015 edition of the

Canadian Electrical Code.

Rationale:

Standards cannot be achieved as written.



4


Fixes ampacities issue from 2012 edition of CEC.

None.

Proposed BC

Amendment

Recommendation,

Impacts, and

Rationale

Adopt with no amendments.



6


Changes from 2012 edition of CEC

None.

Proposed BC

Amendment

Recommendation,

Impacts, and

Rationale

Recommendation:




8


Rule 8 ‐ 106 Use of demand factors

None.

Reference to “qualified person” in Rule 8 ‐ 106 for demonstrated load and not calculated load.

Proposed BC

Amendment

Recommendation,

Impacts, and

Rationale

Recommendation:


BCSA will publish an information bulletin on the application of “qualified person” in Rule 8 ‐ 106.

Rationale:

Clarification can be achieved through a directive or information bulletin.



10


Rule 10 ‐ 802 Material for system grounding conductors

(1) The grounding conductor shall be permitted to be insulated or bare and shall be of copper, aluminum, or other acceptable material.

(2) The material for grounding conductors shall be resistant to any corrosive condition existing at the installation or shall be protected against corrosion.

Proposed BC

Amendment

(1) Except as permitted by

Subrules (2) or (3) , the grounding conductor shall be insulated or bare and shall be of copper , aluminum, or other acceptable material .

(2) A grounding conductor shall be permitted to be of aluminum for installation in dry locations only.

(3) Where a deviation has been allowed in accordance with

Rule 2-030, the grounding conductor shall be permitted to be of other acceptable material.

(2) (4) The material for grounding conductors shall be resistant to any corrosive condition existing at the installation or shall be protected against corrosion.

Recommendation,

Impacts, and

Rationale

Recommendation:

Adopt Section 10 with amendments to Rule 10 ‐ 802.

Impact:

No impact.

Installers will be able to continue use aluminium as an acceptable material for grounding conductors in dry locations.

Rationale:

These amendments enable the continued use of aluminum in dry locations as a cost ‐ effective and safe alternative to copper.

BCSA will publish an information bulletin providing rationale and clarifications on amended provisions.



CEC 2015

Section

10 (Continued)

CEC 2015 Issue Proposed BC Amendment

Appendix B Note on Rule 10 ‐ 002(1)

To have an impedance sufficiently low to:

(a) facilitate the operation of the overcurrent devices in the circuit on the occurrence of a fault of negligible impedance from an energized or phase conductor to exposed metal; and

(b) limit the duration of the voltage above ground on this exposed metal the complete fault path (line ground loop) of the grounding and bonding arrangement of the consumer’s installation would normally have to be such that a current of not less than five times the rating of the overcurrent device protecting the circuit will flow on the occurrence of a fault of negligible impedance.

Appendix B Note on Rule 10 ‐ 002(1)

Objective of bonding is to have an impedance sufficiently low in order to:

(a) facilitate the operation of the overcurrent devices in the circuit on the occurrence of a fault of negligible impedance from an energized or phase conductor to exposed metal; and

(b) limit the duration of the voltage above ground on this exposed metal .

This objective is accomplished by means of the completing the fault path of the bonding arrangement of the consumer’s installation which would normally have to be such that a current of not less than five times the rating of the overcurrent device protecting the circuit will flow on the occurrence of a fault of negligible impedance via a bonding conductor back to the solidly grounded source.

Recommendation,

Impacts, and

Rationale

Recommendation:

Add Appendix B Note on Rule

10 ‐ 002(1) using modified text from Rule 10 ‐ 500 of CEC 2012.

Impact:

None.

Rationale:

Retains information from Rule

10 ‐ 500 of the 2012 edition of the Canadian Electrical Code, which was removed from the

2015 edition.


12

None.

Proposed BC

Amendment

Recommendation,

Impacts, and

Rationale

Recommendation:


Rationale:

BCSA will publish an information bulletin for

Rule 12 ‐ 1414 explaining that a neutral / grounded service conductor can be used as an in ‐ service bonding conductor when

EMT is used as an overhead service raceway.
