Residential Load Calculations
Residential load calculations first appeared in the Canadian Electrical Code Part I (CE Code) in the second edition dated 1930. In the 1930 edition, the load calculation rules were in Section 6 Conductors. The calculations were quite different from the present day calculations. For residential installations, the calculations were based on the number of branch circuits being installed instead of the dwelling floor area. In the fourth edition, dated 1939, a demand factor table for lighting load based on the floor area was added. In the sixth edition dated 1953, the Conductor Section including the load calculation requirements were moved to Section 4 Conductors. This calculation format remained until the seventh edition, dated 1958. A new section called Circuit Loading and Demand Factors including the single dwelling load calculations was added as Section 8 to the eighth edition of the CE Code dated 1962.

SPE-1000 0151 — Model Code for the Field Evaluation of Electrical Equipment
The fourth edition of the SPE-1000 Model Code for the Field Evaluation of Electrical Equipment (SPE-1000) is scheduled to be published by June of this year. The SPE-1000 was first published in 1994 providing requirements used by inspection bodies accredited by the Standards Council of Canada when field evaluating unapproved electrical equipment. Used in conjunction with the requirements of the Canadian Electrical Code (CE Code), Part I, the SPE-1000 document provides construction requirements for the equipment being evaluated along with testing criteria, and minimum marking for equipment nameplates, warning and caution notices. The SPE-1000 does not cover the field evaluation of equipment for use in hazardous locations, medical electrical equipment, equipment connected to line voltage in excess of 46 kV, and individual stand-alone components such as conductors, cable, wiring devices, switches, relays, and timers.

Making Changes to the Canadian Electrical Code
The Canadian Electrical Code consists of five parts. Part I covers the installation and maintenance of electrical equipment, Part II is the safety standards for electrical products, and Part III is for outside wiring. Part IV is the objective-based industrial electrical code, and Part VI, the electrical inspection code for existing residential occupancies. This article will focus on Part I amendments.

Wiring Methods II
Section 4 of the Canadian Electrical Code covering conductors has seen ten revised subrules, eleven new subrules and one new rule for the 2012 CE Code. The most significant change to Section 4 is the addition of new Rule 4-006. Similar to Article 110.14 of the National Electrical Code, Rule 4-006 limits the maximum allowable ampacity of a conductor to be based on the lesser of the temperature rating of the conductor or the maximum termination temperature marked on equipment

Wiring Methods
Section 12 of the Canadian Electrical Code covering Wiring Methods has seen nineteen rule changes and seven new rules for the 2012 CE Code. The first revision is to change the size of the sand cover used for direct buried conductors or cables from 6 mm to screened sand with a maximum particle size of 4.75 mm in Subrule 12-012(4). The reason for the change was to recognise standard sieve sizes detailed in ASTM Standard D 2487.

Being an IAEI Appointee to a Canadian Electrical Code Subcommittee
How may times have you said to yourself? "I don’t understand why that rule reads the way it does. It doesn’t take ________ into account. I think I could have done a better job.” Every IAEI member has an opportunity to participate in development of the Canadian Electrical Code (CE Code). A very effective way is through the subcommittees. That is where the work is done and key decisions are made.
