Section 4 Conductors — Changes from the 2009, 21st edition to the 2012, 22nd edition Canadian Electrical Code
By Pierre McDonald, CET, Senior Regulatory Affairs, Underwriters Laboratories of Canada Inc
Last article outlined the implications and reasons for temperature requirements when sizing conductors using Rule 4-006 and the revised ampacity tables of the 2012 edition Canadian Electrical Code (CE Code). While this is an important rule with respect to the use and installation of conductors, there were several changes within Section 4 — Conductors, which should also be explored.

Rule 4-004(1)(d)(e)(f) for copper conductors and 4-004(2)(d)(e)(f) for aluminum conductors, has been adjusted to remove any ambiguity as to when the Code User can use the IEEE 835 Standard for power cable ampacities.

Previous wording of these rules required the Code User to use the IEEE 835 standard in all cases (in conductor sizes No. 1/0 AWG and larger, in an underground run, directly buried or in a raceway), yet the Appendix B Notes contained Installation diagrams and Appendix D contained ampacity tables associated with these diagrams, all in conformance with the IEEE 835 Standard.

B.C. providing fertile ground for Alberta energy company's investments
Business in Vancouver
B.C.'s second-largest run-of-river project, the 195-megawatt Forrest Kerr power station, officially started selling electrons to B.C. Hydro last month. And while the Alberta company that developed the project on the Iskut River continues to focus on renewable energy projects in B.C., it's a suite of liquefied natural gas projects for both domestic and export markets that might hold the most promise for the up-and-coming energy company.

LED lighting for city parks
Lethbridge Herald
Enjoy an after-dinner stroll around the lake? If you're heading to Nicholas Sheran Park, that walk is becoming a little safer. A contractor is installing light-emitting diode (LED) lights around the lake, as part of a program that's upgrading lights in almost every city park. "It's going fairly smoothly," says Ryan Carriere, the city's parks planning manager. The power-saving lamps, similar to brighter lights recently installed along city streets, will replace a variety of older-style illumination.

Poor nations go for solar, wind at twice the pace of rich ones

Turning 500 tons of manure a day into renewable energy
Huffington Post
Alberta is known for its beef — or more specifically its beef marketing. If you haven't seen the original "I heart Alberta beef" bumper sticker you've definitely seen an homage. But Alberta beef started for a reason, Alberta's grain farmers needed a way to diversify and add value to their product. Grain prices are notoriously volatile and producing a bumper crop didn't always guarantee a bumper profit.

Conductor ampacities and their temperature rating
By Pierre McDonald, CET, Senior Regulatory Affairs, Underwriters Laboratories of Canada Inc.
Sizing conductors as per the Canadian Electrical Code (CE Code) has been a necessary skill requirement for electricians, designers and engineers for as long as I can remember. The rules associated with conductor ampacity have virtually remained unchanged over the years.

Transmission incoming: AltaLink holds consults in Lundbreck and Pincher Creek
Pincher Creek Echo
The atmosphere in the Heritage Inn was electric, almost literally, as AltaLink and AESO employees met with local landowners and residents in the first round of public consultations about a new transmission line project. The plan for the proposed Castle Rock Ridge to Chapel Rock venture is to run lines west from the substation just above Pincher Station to the existing high-voltage 1201L line that run north-south past Burmis.

Consumers will higher power costs
Innisfail Province
The town has agreed on keeping the current eight per cent electrical franchise rate but the average consumer in town will soon be paying just over $8 more on their monthly bills. That is because FortisAlberta is applying to the Alberta Utilities Commission (AUC) a distribution rate increase of five per cent along with a 15 per cent increase in transmission costs, both of which are passed down to the consumer.

Marcia convinced DEEP project is a natural fit in Estevan area
Estevan Mercury
The DEEP Geothermal project in Saskatchewan should be easier to sell in Estevan and Calgary than Toronto's Bay Street. At least that's the assumption the project's promoter is making as she finds herself embedded in the second phase of an exciting electrical production program near Estevan. Kirsten Marcia, a graduate of Estevan Comprehensive School, who holds degrees in geological engineering, sees the Deep Earth Energy Production (DEEP) project as one that local and Calgary-based oil patch and other production people should be able to understand and quickly embrace as doable.
