32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Regulated electrical work

Work that the Electrical Safety Standards Act and its regulation define as requiring a permit and a qualified person, including installation, alteration, and repair of electrical equipment.

Electrical contractor licence

An authorization issued under the Act permitting a business to offer or undertake regulated electrical work, subject to a qualified person being responsible for the work.

Electrical permit

A document authorizing specified regulated electrical work at a stated location; it must be obtained before work begins and requires inspections at mandated stages.

Field safety officer authority

Powers granted by the Act to inspect installations, issue compliance orders, order disconnection of unsafe equipment, and recommend suspension or cancellation of certificates.

Compliance order

A written direction from a field safety officer requiring a specified deficiency to be corrected within a stated time, enforceable through further regulatory action.

Declared electrical equipment

Equipment that must bear certification from a recognized testing agency before it may be sold, offered for sale, or installed in the province.

Incident reporting duty

The obligation to notify the safety authority of electrical incidents causing injury or fire, or of electrical contact, within the prescribed time and manner.

Certificate of qualification

A credential issued under the Act confirming that the holder has met the qualification requirements to perform regulated electrical work within a defined scope.

Canadian Electrical Code Part I

The installation standard adopted by regulation in the province, setting minimum requirements for electrical installations and supplemented by provincial amendments and bulletins.

Approved equipment meaning

A defined code term meaning equipment acceptable to the authority having jurisdiction, typically evidenced by certification from a recognized testing agency.

Ampacity correction factors

Multipliers applied to table conductor ampacity to account for ambient temperature and conductor bundling, applied together to determine the permitted current-carrying capacity.

Bonding definition

A permanent low-impedance connection between metal parts ensuring electrical continuity and the capacity to conduct fault current safely to the source.

Grounding electrode system

The set of electrodes and conductors connecting the electrical system to earth, governed by code rules on type, installation, and connection to the service neutral.

Overcurrent device rating

The current rating and interrupting capability of a fuse or breaker, which must protect conductors at their ampacity and withstand available fault current.

Raceway fill limits

Code table limits on the proportion of a conduit's cross-section occupied by conductors, calculated from conductor area and raceway internal area.

Code amendment precedence

The rule that provincial amendments and published bulletins modify or supersede the base code text where the two differ, and the more restrictive applies.

Demand load calculation

A method that applies code-permitted demand factors to connected loads to determine the service or feeder load used for sizing conductors and protection.

Two-wire voltage drop

Calculated as VD = 2 × L × I × R, using one-way length, load current, and conductor resistance per unit length at operating temperature.

Three-phase voltage drop

For a balanced load, VD = √3 × L × I × R, where L is one-way length, I is line current, and R is conductor resistance per unit length.

Motor branch circuit sizing

Conductors and short-circuit protection are sized from code motor full-load current tables rather than nameplate current, with separate overload protection rules.

Available fault current

The prospective short-circuit current at a point in the system, which must not exceed the interrupting rating of devices or withstand rating of equipment.

Working space clearance

The code-required clear area in front of electrical equipment, maintained for safe operation and maintenance and free of storage or obstruction.

Fault path impedance

The total impedance of the bonding and grounding path during a fault, which determines whether the overcurrent device clears the fault within the required time.

Service conductor sizing

Selection of service conductors with corrected ampacity at least equal to the calculated demand load and coordinated with the service overcurrent protection rating.

Lockout verification

The process of isolating all energy sources, applying personal locks, and testing for absence of voltage with an instrument verified on a known source.

Energized work authorization

A document permitting work on energized equipment where de-energization is infeasible, recording hazard assessment, required PPE, and qualified supervision.

Arc flash risk assessment

An evaluation establishing incident energy or PPE category and shock approach boundaries for a task before energized work is permitted to proceed.

Electrical safety program

A documented set of hazard identification, risk assessment, written procedures, training, and audit activities governing electrical work by the contractor.

Incident root cause analysis

A structured investigation identifying the underlying cause of an electrical incident, the corrective action taken, and the records supporting regulatory reporting.

Compliance audit

A comparison of site practice against permit conditions, code requirements, and written safety procedures, used to identify and correct deficiencies before enforcement.

Qualification scope matching

The principle that assigned duties must fall within the worker's certified trade scope and documented supervised experience, verified through training records.

Record retention period

The length of time permits, inspection results, maintenance logs, and incident reports must be kept, as specified by the regulation and permit conditions.
