Conventional electrical outlets have a neutral wire and two 120-volt wires that deliver the power to appliances and devices in your household using a single phase of the electrical service. A 240-volt electrical outlet works differently by using both the neutral and 120-volt wires, as well as the ground wire to power one receptacle. The ground wire may be standard in new homes, while older appliances and homes would typically use the three-prong 240-volt outlets. A lot of motor-driven, big appliances can run more efficiently on 240 volts, so outlets have been created specifically for them. If you are buying 240-volt electronic appliances, you need to make sure that you know how to use them safely. Here are some tips:

• Check the power label of the appliance – Reputable manufacturers would provide the power supply information on every device they make, so look for that to verify the voltage of your device. It can be a label on the back of the appliance or molded into the plug’s plastic. In some cases, it can be on an AC transformer box along with a power lead. It usually contains an information whether a voltage converter will be needed to power the 240-volt electronic appliance safely.
• Use only with a compatible 240-volt plug – You cannot plug a 240-volt electronic appliance directly into any other outlets, as the prongs are designed specifically for receptacles that can accommodate them. A 240-volt outlet is bigger than smaller, conventional receptacles. It has rounded tops with three to four holes, depending on the age or when it was installed. Three-prong ones have two diagonal holes on each side, and a hole resembling a backward L on top. A four-prong receptacle has an L on the top, a half-circle hole at the bottom, and two side holes positioned vertically.
• Know the 240-volt electronic appliances – A lot of large appliances will require 240 volts. You will need to install an appropriate receptacle for them or get an adapter to make sure that their prongs can fit in the socket. These appliances are usually ovens, cooktops or cooking ranges, furnaces, water heaters, clothes dryers, garage power tools, air-conditioners, furnaces, and electric cars.
