The Code is a comprehensive document. Sometimes it can seem quite daunting to quickly find the information you need. This series of articles provides a guide to help users find their way through this critical document. This is not intended to replace the notes in Appendix B or the explanations of individual requirements contained in the CEC Handbook** but will hopefully provide some help in navigating, while reading the code.

The 24th Edition of the CE-C, Part I, (C22.1-18)* is now available from CSA Group. This discussion of Section 78 — Marine Wharves, Docking Facilities, Fixed and Floating Piers, and Boathouses is based on the new edition.

In this article: Tables — Part B. This section of the Code contains 99 tables of essential information that is referenced by various Rules of the Code. Tables referenced by Rules are considered normative (mandatory) elements of the Code. Note that the D tables of tabulated information in Appendix D are considered non-normative (non-mandatory) elements. The tables are in numerical order based on when that table was included in the Code. Since this is a large section it will be discussed in two parts. This is Part B covering Tables 36 to 69.

Tables 36A and 36B, referenced by Rule 4-004, provide maximum allowable ampacities for aluminum and copper conductor, respectively, neutral supported cables, based on phase conductor size, and type.

Table 37, referenced by, Rule 28-104, provides motor supply conductor minimum temperature rating based on, an ambient temperature of 30 degrees centigrade, type of motor enclosure, and class rating of the insulation.

Table 38, referenced by Rules 8-202 to 8-210 provides the demand factors for electric vehicle supply equipment, based on the number of automobile spaces or stalls per feeder, and the maximum load in watts per space or stall.

Worker RiskMany of us take risks in their daily lives, such as using our cell phone while driving or exceeding the speed limits, while fortunately avoiding any potential injury and damage. We are rewarded by a certain convenience when we take risks, such as apparent time savings as well as the tacit approval of observers who do not oppose our risky behaviour.

To reduce injuries in the workplace, we must all recognize that we are accepting certain risks on a daily basis and acknowledge the factors influencing risk tolerance.

More than 70% of workers believe there is an opportunity for more electrical safety training in the workplace, according to a January 2020 Fluke survey of 162 electrical workers. Three reasons why electricians may feel they don't get enough safety training for their jobs are because effective programs take a lot of time to set up, employees are often not engaged in the training or safety meeting, and safety isn’t talked about in a way that builds toward a strong safety program. Here’s what you can do to create a stronger training program.
