Take this opportunity to test your knowledge of the Canadian Electrical Code – Part 1. Here are four questions on 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. Answers will be posted on our website in a few days and published in our next issue. Good luck and share your results with our Facebook group: Canadian Electrical Contractor Discussions.
Motors and Generators
Q1: What determines the insulation temperature rating and ampacity of motor supply insulated conductors?
Q2: 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?
Q3: Does each motor branch circuit, starter or controller require a separate disconnecting means?
Q4: Does a generator driven by electricity supplying a 2-wire grounded system need a protective device that disconnects both insulated conductors?
