A step-down converter is used to step electricity down from 220 volts to 110 volts. Step-down converters are used when traveling outside of the United States, where many countries' electrical systems use 220, 230 or 240 volts.Continue Reading
Without a step-down converter, appliances manufactured for a 110-volt outlet will suffer a shock failure when plugged into a 220-volt outlet. While adapters are available, the adapter is only for the outlet pattern; it doesn't change the voltage of the outlet.
Step-up converters are also available for items purchased outside of the United States, allowing the buyer to use a 220-volt appliance with a 110-volt outlet when he or she returns home. Some models may be used for both stepping up and stepping down the electricity, making it easy for a traveler to use a hair dryer or electric razor in any country.Learn more about Electrical
The standard voltage of a home electrical outlet in the United States is 120 volts, although the actual voltage supplied may be as low as 110 volts, due to line conditions. A few appliances, like stoves and electric dryers, may use 240 volts, which require special wiring and outlets.Full Answer >
A GFCI outlet, or ground-fault circuit interrupter, is an outlet that stops electricity from flowing through it if it detects a problem or a ground-fault. The outlet trips, the same as a breaker trips in an electrical panel, as a safety measure.Full Answer >
A multimeter is able to let you know how much electricity is flowing through a wall outlet. Though it generally is not a good idea to insert objects into a wall outlet, a multimeter only works when you insert its probes into an outlet. There is a safe way to do this.Full Answer >
To install a 220-volt outlet, obtain the necessary permits, turn off the power, run a new cable from the sub-panel, cut a hole for the new outlet and attach the cable's wires to the new outlet. Hire a licensed electrician to make the connection at the breaker box.Full Answer >
