What is the standard voltage for residential wiring in Canada?

In Canada, the standard voltage for residential wiring is 120/240 volts. This configuration allows for the use of both 120-volt circuits, which power most household appliances, lighting, and outlets, and 240-volt circuits, which are typically used for larger appliances like dryers and ranges.

The system consists of a split-phase service where a single-phase supply of 240 volts is split into two 120-volt lines. This provides versatility in voltage usage across different types of devices and appliances within a home. While the individual circuits often operate at 120 volts, the ability to have 240 volts available enhances the efficiency and capability of the residential electrical system.

Other voltage options mentioned do not apply to the standard residential wiring in Canada. For example, 240 volts alone does not reflect the full residential capability, 110 volts is an outdated standard and not common practice anymore, and 480 volts is typically used for industrial applications, not in residential settings.
