Guide to the Canadian Electrical Code, Part I — Instalment 34
Apr 25, 2021
Take this opportunity to test your knowledge of the Canadian Electrical Code - Part 1. Last week we published questions about motors and generators. You'll find the answers in EIN articles written by our code experts — mainly Bill Burr and Terry Becker — and of course in your own best practices. Good luck and share your results with our Facebook group: Canadian Electrical Contractor Discussions.
Motors and Generators
Q: What determines the insulation temperature rating and ampacity of motor supply insulated conductors.
A: Rule 28-104 outlines the use of Table 37 to determine the insulation temperature rating and ampacity of motor supply insulated conductors.
Q: Where do you refer to determine the ampacity rating of insulated conductors supplying individual motors, two or more motors, or feeder and secondary insulated conductors?
A: Rules 28-106 to 28-112 outline the use of Table 27 to determine the ampacity rating of insulated conductors supplying individual motors, two or more motors, or feeder and secondary insulated conductors. A chart in Appendix B will help with these calculations.
Q: Does each motor branch circuit, starter or controller, and each require a separate disconnecting means. A single disconnecting means may serve more than one function or motor grouped on a single branch circuit.
A: Rule 28-600 requires that each motor branch circuit, starter or controller, and each motor be provided with a separate disconnecting means. A single disconnecting means may serve more than one function or motor grouped on a single branch circuit.
Q: Does a generator be driven by electricity supplying a 2-wire grounded system need a protective device that disconnects both insulated conductors?
A: Rule 28-904 requires a generator not driven by electricity supplying a 2-wire grounded system to have a protective device that disconnects both insulated conductors.

Five Tips to Find Time for Field Service Marketing
Time is a precious resource that we all want more of. And if you own a field service business or work for one, you undoubtedly know how hard it is to find time for everything you need to accomplish in a workday, let alone a week, a quarter, or a year.
Like many of us, you do your best to check every item off of the to-do list during working hours while inevitably pushing lower priority items off to another day. And often, marketing your field service business is one of those things that easily falls to the wayside after being pushed back for more urgent matters.

The RenuWell Project partners are excited to announce the groundbreaking of two pilot sites located near Taber, Alberta. These pilot sites are the first of their kind to repurpose inactive oil and gas infrastructure as a foundation for renewable energy development and job creation.
When operating, the solar projects will generate 2,030 MWh annually – enough electricity to power 280 average Alberta households or irrigate 11,700 acres of farmland for an average year. This is roughly equivalent to $200,000 in electricity sales per year with 1,100 tCO2e savings in GHG emissions. Over a 25-year lifespan, the projects will generate 50,750 MWh, with GHG emission savings of 28,420 tCO2e.

The Occupational Safety and Health Administration (OSHA) estimates 350 employees are killed annually in electrocution accidents, which roughly equals one fatality per day. In the face of these dangers, OSHA officials and industry safety consultants alike recommend eliminating potential hazards on work sites, rather than simply relying on contractors or employees to follow safety guidelines.
To help safeguard employees from electrocution, Emerson has launched its Appleton™ Powertite™ Lock Collar, a device that fastens over plug and connector connections and is secured with a padlock, preventing unauthorized personal from disconnecting the cable connection once in place.
