Regardless of their colour. Even the so-called neutral ones. All electrical wires could carry an electrical current at some point, so treat every colour wire with equal caution.

NOTE: Sometimes with older wiring, the electrician may have marked the white wires with red or black to show that the white wire is indeed hot.

All black, red, and blue (and yellow) wires are hot or live. White wires can carry live current in certain circumstances, as can green (such as when a short circuit occurs).

*When a bulb displays "Up to" a certain number of lumens in its specifications, it displays the maximum lumen output of the bulb. It shows how bright the bulb can get at 2700 K (White bulbs) or 4000 K (White ambiance or White and color ambiance bulbs). Learn more about brightness.

Now that we know the basics of our Canada wiring colours and how they function, let’s take a more detailed look at each of the colour codes and the functions they denote.

Just a quick reminder. Even if you know your Canada wiring colours by heart, it’s never a good idea to DIY electrical projects of any description.

The hot wire will initialize the circuit but once the electrical current is flowing, another wire is necessary for the circuit to fulfill the intended purpose of the current.

Black is the main colour of hot wires for most homes – hot wires are those that are always carrying a live electrical current. Black wires are used primarily to feed current to power electrical outlets and switches, which in turn, power the appliances and lights in the home.

Some insurance companies will not cover an electrical fire if they discover that the electrical work was not completed by a licensed electrician.

What exactly is a hot or live electrical wire? A hot electrical wire is used as the initial power feed to a circuit and acts as the carrier or conductor of electrical current from the power source to the outlet where it is required.

Even though green typically means it is a ground wire, sometimes you’ll find that bare copper wire (with no insulation) or a green wire with yellow striping may be used.

Conduits are generally made from plastic or metal pipe and provide protection for blue and yellow hot wires against corrosion or damage.

At the end of (economic) life dispose the product according to local rules and do not dispose the product with regular household waste. The correct disposal of your product will help prevent potential negative consequences for the environment and human health

Again, like white wires, just because your green ground wires don’t normally carry current, it doesn’t mean they never do. There will be current running through a ground wire while they are dealing with the overloaded system. Handle with care.

Blue = Hot wire, always carrying electrical current, but pulled through a conduit and primarily used as a travelling wire for 2- or 3-way switch applications (to control one appliance or light using multiple switches).

According to Canada wiring codes, blue and yellow hot wires are not typically used for power outlets. They are generally utilized to power 2-way or 3-way switches, where multiple switches are used to control hall lights or stair lights, for instance.

Don’t be deceived by the word ‘neutral’ though. Although an electrical current isn’t always passing through a white wire, you must handle this neutral wire with the same caution as when you handle a hot wire.

In Canada, electrical wires are colour coded to make it easy to differentiate and identify each wire, with each Canada wiring colour representing what that wire does and what it’s used for.

Photometric lights use photometric (light energy) values that enable you to more accurately define lights as they would be in the real world.

Perhaps, even more importantly, to avoid harm to yourself, your family, or your home, it is prudent to leave all electrical work to a qualified electrician.

You can change the color of your Hue Play light bar with the Hue app, which connects to your lights via the Hue Bridge (sold separately).

Green wires or green wires with yellow stripes are the protective ground or earth wires. Ground wires are also sometimes bare copper (with no coloured protective casing).

You don’t need to be a rocket scientist – or an electrician – to know and understand, that the specific colouring of the electrical wires in your home means something.

They are always carrying electricity, which means it is dangerous to touch a hot wire while there is a power source feeding it. It goes without saying but always bears repeating, do not touch a hot wire of any colour unless there is no connected and operating power source.

Not unlike black wires, red electrical wires are also used for hot wires, although they are primarily used for switch legs (like for a ceiling fan).

That being said, it is helpful to know and understand what the Canada wiring colours mean as they pertain to your home and your safety.

You’ll find red wires in use to power smoke detectors that are hardwired to your electrical system. More specifically, red wires are used as the second hot wire in 220-volt installations.

Premium Electric only employs fully bonded, certified electricians who are 100% committed to the smooth and safe running of your electrical circuits.

This is where the white, neutral wire comes in. The circuit will be carried back to the power source by the neutral wire, thus completing the circulation of the AC electrical current.

Ground wires, also sometimes called earth wires, act to protect against an electrical current that may be unstable by taking errant currents out of the equation and ‘grounding’ them to the earth. If there’s a short circuit, ground wires redirect the unwanted electricity to eliminate any risk of electrical shock or electrocution.

You can use the included bracket with the included adhesive to mount the Play light bar behind your TV. Your instruction manual has detailed instructions on mounting your Play light bar behind your TV.

Not only is it incredibly dangerous, but it’s also important to get your wiring installed and checked by a licensed electrician and inspected independently to ensure CEC compliance.

A single Hue Play light bar power supply can power up to three Play light bars at once. The Play light bar’s base unit includes a power supply — the part of the lamp you plug into your wall socket. The Play light bar extension does not include a power supply; simply plug the extension into your existing Play’s power supply to extend your setup.

Before we dive into explaining the Canadian wiring colours and how it applies to the wiring in your house, let’s make one thing clear: the most important thing you need to know about electrical wires and their colour coding is that ALL electrical wires are electrical.

We offer a full range of professional electrical services and serve clients throughout the Vancouver Lower Mainland and the Fraser Valley including:

A hot electrical wire is one which is carrying live electrical current, and which will cause an electrical shock if you touch it. Black, red, blue, and yellow wires are all hot, but white and green wires can be hot also at certain times or in certain instances.

Mount the Play light bar behind your TV using the included adhesive, place it horizontally on any surface (such as on either side of your TV), or use the included vertical stand to stand the Play light bar upright.

However, if a short circuit or another anomaly should occur, the ground wire is there to remove the unstable current by sending it into the ground to neutralize it.

Canada wiring colours, as regulated by the Canadian Electrical Code (CEC), are quite similar to the National Electrical Code (NEC) in the United States.

To explain this in more specific terms: under normal conditions, when your electrical system is functioning normally and safely, the ground wire does not carry an electrical current.
