Frequency and voltage supplied to most premises by country Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices. (For industrial machinery, see industrial and multiphase power plugs and sockets.) Some countries have more than one voltage available. For example, in North America, a unique split-phase system is used to supply to most premises that works by center tapping a 240 volt transformer.

Voltage (measured in volts) refers to the force or pressure at which electricity flows. It is similar to the pressure of water in a pipe.

3. Unplug when not in use: Even when appliances are turned off, they may still consume energy if they are plugged in. Unplug devices when not in use to eliminate any energy drain.

Each 110-volt circuit connects to a single bus bar and has only one hot wire, so only one circuit breaker is needed. By contrast, a 220-volt circuit connects to both bus bars, so two breakers are needed – one for each bus bar and each wire that connects to that bar.

The nominal voltage between each hot bus and the neutral bus is 120 volts. As electricity courses through circuits in the house, the voltage fluctuates, which accounts for the different designations.

(3) British type G sockets are common in Riau Islands due to their close proximity to Singapore. British type G sockets are often used as dedicated sockets for air conditioners as well.[citation needed]
