Canadian Electrical Code, Section 46, Emergency Systems, Unit Equipment and Exit Signs provides installation and maintenance requirements for standby power for essential services when the regular power supply fails.
This article revisits some definitions and requirements covered in Section 6 of the Canadian Electrical Code, Services and Service Equipment, beginning with a review of some often mentioned terms.
The Canadian Electrical Code, Section 6 provides us with some important rules for installing service equipment, wiring methods and metering.
Usually, good grounding and bonding methods and isolation of data processing equipment from sources of transient voltage interference and electrical noise are the easiest and best ways to correct transient voltages and electrical noise problems, or to prevent them from happening in the first place.
What should happen when the electrical utility or a utility customer decides to convert the ungrounded 600 volt, 3-wire supply to a 600/347 volt, 4-wire, solidly grounded electrical supply?
A National Standard of Canada, CAN/CSA-B72-M87 Installation Code for Lightning Protection Systems provides guidance on lightning protection.
In this article, we will cover some of Canadian Electrical Code requirements for standby power and transfer switching.
But is the information contained in the Canadian Electrical Code enough for our purposes – or do we need to look further afield to find out more?
The 1998 Canadian Electrical Code has made some more changes in the rules for underground conductor ampacities.
Usually we can assume that the rules of the Canadian Electrical Code are based on some basic principles, which don’t vary a whole lot — to minimize the possibilities of electrical fire and shocks. But are the rules ever in direct conflict with each other or their principles?
