Electrical Grounding & Bonding (CEC-2018- Section-10)
Electrical grounding and bonding are very important part of every electrical systems, and electrical systems safety and security depends on bounding and grounding.
Bounding and grounding for commercial and residential electrical wiring is similar. The main purpose of grounding and bonding is to make sure to drain all current from system and prevent electrocution and hazards due to electrical.
Residential grounding and bounding
All electrical items, devices, boxes, lights, plugs have to be grounded to the main electrical panel in residential buildings. Different types of electrical groundings are:
- Main house grounding (the main house grounding is usually connected to street side of water meter or grounded with grounding rod or ground plate.
- Receptacle grounding (all electrical plugs need to be grounded)
- Lighting and light switches need to be grounded
- all other electrical in the residential units have to be grounded
Can Electric, as Edmonton electrical contractor we provide electrical inspection for grounding to your homes to make sure that, your grounding is according to electrical code and best serving you and your family.
Our Edmonton electrician, after inspecting your home for electrical code compliances will provide a detail report about your home grounding situation make recommendation that best serve your safety and provide a detailed report for your insurance company to help you get better home insurance rate.
Gas pipes in residential units need to be bonded to main electrical ground, and if your sewer line is old metal cast it has to be bonded. For grounding requirement in your jurisdiction please consult with your electrical code and inspection authority.
Commercial bonding and grounding
Similar to residential all machines, devices, equipment, plugs, switches and light need to be grounded and the size of bonding and grounding conductors can be different, and they are determined based on size of main electrical service and related devices and amperage of devices that need to be grounded.
One of the important parts of commercial grounding can be IG plugs, which is special types of plugs and the grounding that are though insulated conductor. This type of plugs are used for server rooms, sensitive electronics and anywhere in the building where extra safety is required. Also See : https://canelectric.ca/landing/feb-2020/
GFCI & AFCI Protection
GFCI breakers, is designed to protect you from electrocution and AFCI-breakers are designed to protect your house from fire. they both come in the form of plugs and breakers.
GFCI-breaker will insulate circuit and interrupt when there is any fault between ground and hot wire and AFCI breakers will engages and trip the circuit when there is arcing in the circuit. based on CEC, you cannot substitute GFCI breakers with AFCI-breakers and AFCI breakers with GFCI-breakers, because functionality of this tow type of breakers are different.
AFCI protection (CEC-2018- C22.1-18)
Most plugs in the new houses have to be protected through Arc-breakers. main function of AFCI are to detect any arcing in the circuit that might cause fire and the moment the arc and sparking is detected by AFCI- the breaker will activate and disconnect the circuit to protect the system from fire.
All electrical plugs in living room, dining rooms, bedrooms, family rooms, kitchen, laundry rooms, hallways, and dens need to be AFCI-protected. locations in the house that don’t need AFCI breakers are, exterior plugs, garage, bathrooms, and furnace.
GFCI protection (CEC-2018- C22.1-18)
Locations and places close to water, electrical devices need to be GFCI-protected for example, Kitchen, bathrooms, bathtubs, crawlspace, garages, exteriors, unfinished basement, and unfinished accessory buildings (storage, sheds, hot tubs, jacuzzi, swimming pools, and spas).

Some electrical requirements for residential
Based on CEC-2018 electrical wiring for residential need to meet the following reequipments and more:
- All receptacles need to be TR and no living area should be away more that 6 feet from a receptacle (maximum distance between two plugs-12 ft or less)
- All permanent applicants and equipment’s need dedicated circuit with rated voltage and amperages.
- All rooms and living areas need at least one light switch located on wall at the point of entry where is easily seen and accessible.
Electrical panel (CEC-2018- Section-8)
It has to be easily accessible and with at least one-meter clearance in front of panel and It can’t be installed in closet, wet area, stairs way or any location that might not be easily accessible.
The main disconnecting breaker has to match amperage rate for electrical service and the size of wire and service coming into the property. always use double pole breakers for circuits that need 220 volts and also use double pole (handle ties) for 120 volts circuits that protect double-circuit branch circuits.
Make sure you close and fill all unused panel openings and label all breakers, fuses, and disconnects and provide a panel directory.

Electrical Boxes (CEC-2018-12-3000)
When wring electrical it is important to consider the following:
- Ensure the boxes are rated for the use and location (interior and exterior)
- Ensure that the box size enough to accommodate all the wires and devices that will be installed in the box
- Ensure all junctions’ boxes are accessible
- maximum gap between drywall and electrical should be 1⁄8″ or less
- install receptacle boxes flash with any combustible material
- Ensure that minimum of 3″ of wire is extending the electrical box.
- Use electrical boxes that are rated to support ceiling fans and heavier lights.
Electrical wires and cables (CEC-2018-Section-4)
First thing to do about electrical wires to ensure and check the wire AWG (American wire gauge), whenever you want to use it, and types and rate of wires insulation for proper amperage and wire insulation.
Run the wire not closer than 1.25″ to the edge of joists otherwise you have to provide mechanical protection for wire (Use nail plates).
Use proper and approved clamps wire connectors and fasten and staple wires and cable every 8″ (0.2032M) close to electrical box and every 54″(1.3716M) along runs. Pigtail wire connectors when need it and there is more than one wire in the box. Use and run wires and cables in approved conduit based on CEC requirements.
Ensure that light switches are easily accessible at the entrance and avoid installing switches behind door and usually are installed 42″-to-50” high from finished floor.
Use three ways switches at the top and bottom on stairways and four ways electrical switches in hallways. switches that are most commonly used in residential are: Regular switch, decora switch, single pole switch, 3-way-switch, 4-way-switch, dimmable switch, timer switch, motions sensor switch, pilot switch, specialty switch, programable timer switch, and other types of switches.
Electrical Receptacles (CEC-2018-26-720)
CEC requires that all electrical receptacles installed in residential and places that are within reach of children to be TR (tamper resistant receptacle) rated and 3‑slot-grounded receptacle and installed that the distance between every two plugs is 12 ft. or less.
Install GFCI receptacles or GFCI-protected circuits in bathrooms, kitchens, garages, not-finished basements, and exterior locations and use in-use rated receptacle covers for all exterior electrical outlets. they come in different forms and shapes like regular, decora, and other shapes and forms.
All kitchens counter outlets must be 20‑amp rated and not more than two plugs on a separate circuit and wire a dedicated 15‑amp for dishwashers, fridge, microwave, hood fan/microwave, washing machine, and food disposals.
Electrical light Fixtures (CEC-2018-30-400)
While wiring and installing light fixtures main points to consider is to make sure that bulbs you install are rated for light fixture wattage and the light fixture supporting box is fasten and able to support light. they come ins forms of, ceiling fixtures, scan lights, spots lights (IC and non-IC), chandlers, ceiling fan/lights, and many other forms and shapes.
Smoke detectors, carbon monoxide alarms and combo (Smoke and carbon monoxide) (CEC-2018-32-200)
Based on CEC-2018, every room and living rooms, hallways, and furnaces rooms need at least one smoke/ carbon monoxide alarms that are interconnected and hard wired with all other smoke/ carbon monoxide detectors in the house.
