Ontario Electrical Safety Code, Ontario Regulation 164/99
The Ontario Electrical Safety Code, Ontario Regulation 164/99, is comprised of the Canadian Electrical Code Part I (CEC) together with specific Ontario Amendments. Development of the Canadian Electrical Code Part I is led by the Canadian Standards Association (CSA). It is developed in close consultation with volunteer technical committees and subcommittees reflecting expertise from across Canada, including ESA. After review, the provincial government then adopts the CEC, with additional amendments specific to Ontario.
The Ontario Electrical Safety Code is mostly a technical document and is prescriptive in approach. The Code describes the standards for electrical installations, products and equipment in Ontario in detail.
You can decrease the risks of fire, shock, and electrocution by taking steps to ensure those who perform electrical work are qualified, competent and licensed.
Ontario Electrical Safety Code (27th edition/2018)
ESA collaborated with its safety partners on the 2018 edition of the Ontario Electrical Safety Code. The Minister of Government and Consumer Services approved the adoption of the new Code, which came into effect May 16, 2019. Electrical work conducted after this date must meet its requirements.
The 27th edition of the Ontario Electrical Safety Code includes the Canadian Electrical Code, Part 1, plus Ontario-specific amendments. The Code reflects changes in technology and the market, feedback from stakeholders and technical reviews, and new safety insights.
Changes aimed at improving electrical safety and protecting workers and the public include:
- A re-write of Section 10 requirements for bonding and grounding. These have been reorganized and reduced in size. Some changes will improve safety and simplify the installations;
- Expanded use of tamper-resistant receptacles in educational facilities and hotels/motels;
- A requirement to install an identified (neutral) conductor at each control (switch) location of permanently installed luminaire;
- Alignment with the Ontario Building Code to prevent the installation of high-voltage conductors over buildings;
- Providing adequate working space for electrical workers to repair, maintain and install transformers greater than 50kVA;
- Banning the installation of cables in concealed locations in corrugated roof decking;
- Adding requirements for Energy Storage systems; and
- Advancing the use of power over ethernet as a pathway for sources of electricity.

ESA has partnered with the CSA Group to offer the Code book and all ESA bulletins for one price. The bulletins provide important updates and interpretations. The package is available in print for $219 or in searchable, digital format for $195. The digital format is accessible on smart phones, tablets and desktops and is compatible with Windows and iOS. (Please note: Bulletins are available online. After buying the Code book, register at CSA Communities for access to them.)
Electrical symbols virtually represent the components of electrical and electronic circuits. This article shows many of the frequently used electrical symbols for drawing electrical diagrams. Though these standard symbols are simplified，the function descriptions can make you understand clearly.
Below lists the most commonly used electrical and electronic symbols that can help you get started quickly.
|Name||Electrical Symbol||Alternate Symbol||Description|
|ground/earth||This symbol identifies an earth(ground) terminal used for a zero potential reference point and electrical shock protection.|
|equipotential||It is a symbol to identify parts with the same voltage (i.e., the same electrical potential or equipotential). Since equipotential surfaces all have the same voltage, you won't be shocked if you touch two such surfaces unless you are also touching another part with a different potential from the first two parts.|
|chassis ground||It is a link between different metallic parts of a machine to ensure an electrical connection between them. It must not be considered as a link to the earth.|
|battery||It is a device that consists of one or more electrochemical cells with external connections to empower electrical devices and generates constant voltages.|
|resistor||It is an electrical component that reduces the electric current, for example, to limit the current passing through an LED. A resistor is used with a capacitor in a timing circuit.|
|attenuator||It is an electronic device that reduces the power of a signal with appreciably distorting its waveform, which is the opposite of an amplifier.|
|capacitor||It is a device with two terminals, which stores electric energy. The effect of a capacitor is known as capacitance. It can also be used as a filter to block DC signals but pass AC signals.|
|accumulator||It is an energy storage device that accepts, stores, and releases energy, increasing or relieving pressure in the system.|
|antenna||An antenna also knows as an aerial, is a device designed to transmit or receive electromagnetic (e.g., TV or radio) waves.|
|loop antenna||A loop antenna is a radio antenna consisting of a loop (or loops) of wire, tubing, or other electrical conductors with its ends connected to a balanced transmission line.|
|crystal||A crystal oscillator uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with an exact frequency.|
|circuit breaker||A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.|
|fuse||A fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit.|
|ideal source||An ideal voltage source is a two-terminal device that maintains a fixed voltage drop across its terminals. It is often used in the simplified analysis process of a real electric circuit.|
|transducer||A transducer is a device that converts energy from one form to another. Usually, a transducer converts a signal in one type of power to a signal in another.|
|inductor||A coil of wire creates a magnetic field when current passes through it. It may have an iron core inside the coil. It can be used as a transducer converting electrical energy to mechanical energy by pulling on something. It is a passive two-terminal electrical component used to store energy in a magnetic field.|
|explosive squib||Explosive squib is often used on stage and film to trigger various special effects.|
|sensing link squib|
|surge protectors||Surge protectors protect your electronics from power surges in your electrical system.|
|instrument||For example, a voltmeter is an instrument used for measuring the electrical potential difference between two points in an electric circuit. The wattmeter is an instrument for measuring the electric power in watts of any given circuit.|
|delay element||The delay element provides a specified delay between the actuation of the propellant-actuated devices.|
|permanent magnet||A permanent magnet is a material or object that produces a magnetic field.|
|bell||The electric bell is found in an ordinary house doorbell, and when activated, it makes a ringing sound.|
|buzzer||An electrical buzzer is similar to the bell that makes a constant buzz noise instead of a single tone or bell sound.|
|lamp||A transducer converts electrical energy to light, used for a lamp providing illumination, for example, a car headlamp or torch bulb.|
|speaker||A speaker can take digital input and turn it into analog sound waves—one of the most important parts of a wide range of electrical products like TVs and telephones.|
|oscillator||It produces a repetitive electronic signal, often a sine wave or a square wave.|
|AC source||Alternating Current, continually change direction.|
|DC source||Direct Current, always flow in one direction.|
Each electrical component may have numerous representations as the electrical symbols can vary from country to country nowadays. Some electrical symbols become virtually extinct with the development of new technologies. In cases where there is more than one universal electrical symbol, we have tried to give an alternate representation.
How to Find and Use Electrical Symbols
Open EdrawMax and an extensive collection of electrical diagram templates can be found in the Electrical Engineering category. Click the icon of Basic Electrical to open the stencil that includes all symbols for making circuit diagrams. Making an electrical diagram becomes easy when you have access to thousands of electrical templates and symbols at your fingertips.
As you are into the workspace of EdrawMax, drag the symbol that you need directly onto the canvas. You can resize the selected symbol by dragging the selection handles. A double-sided arrow shows the direction to which you can move the mouse, and you can only move the symbol when a four-direction arrow appears.
In EdrawMax, you can also change the shape of the symbol via the floating menu. It shows when the symbol is selected or when the pointer is over the symbol. For example, the resistor can have 12 kinds of variations. Look at the video below to see the various electrical symbols and create your own circuit diagram in minutes!
