120 Volt Outlet: Everything You Need To Know

The standard electrical outlet plug lamp or vacuum in 120 outlets. The outlet close to the washing machine is seen connected at different points. In this post, we will cover detailed features of a 120-volt outlet and its working. So let’s get started with the introduction to a 120-volt outlet.

How Electrical Voltage Works

• The voltage is pressure from the power supply that is applied to charged electronics through conductors. That is the current moving in the circuit. Voltage is produced through the creation of electrical charges such as EMF  from a generator.
• Household devices use a certain amount of voltage. If voltage varies high or lower than a certain value, the devices an affected. It also causes sparks, produces noise, and catches fire. The contact of a machine where the voltage is not in normal range causes electrocution

What Is a 120V Outlet?

• The standard 120-volt outlet comes with a 120-volt wire and neutral wire. It also comes with a ground wire. There are two basic types of 120-volt outlets: 2-prong and 15-amp outlets.
• They do not have grounding holes and are used in older types of homes.
• The latest electrical outlets come with a 3-prong design and work for 15A or 20A.
• The new devices and chargers used for laptop computers are connected to 3-prong outlets. The 120V outlet is used for residential lighting and small appliances.

Features of 120-Volt Outlet

• It is a standard electrical outlet. It is an older type of outlet that has been used since the 1950s. it is used for all devices used at home.
• it comes with 3 holes, 2 parallel rectangular holes.
• 1 is connected with live wire and the other with neutral wire. The 3rd hole is round and connected with ground wire. The latest 120-volt outlets provide power to pliarized plugs.
• These plugs come with high rectangle prong for neutral wire.
• The 120-volt outlets are used for different devices. They come with certain currents for device operations.

120V vs. 240V Outlets

• The 240-volt outlet provides double the power of the 120-volt outlet, and it uses different electrical wiring.
• The thin-gauge wire is used for 120-volt outlets.
• The larger gauge is used for supporting the power needs of a 240-volt outlet.
• The wiring is connected with a separate double pole breaker in the electrical panel.
• The connection process of the 240-volt outlet comes with larger power use. So there is a need for extra precautions like insulated tools and the use of safety gloves.

Does the Type of Outlet Affect the Cost of Electricity?

• There is no high difference in expenses for 240-volt and 120-volt outlets. The fewer amps for 120-volt outlets use less power as compared to 240 volts.
• For using 240 volts of power for different devices and lights, bills will be high. This is due to the connected larger number of devices.

Can a 120V outlet be converted to 240V?

• There is no option for conversion of one type of outlet to another. If there is a need for an advantage of 240V power, then comes with an existing 120-volt outlet replaced or a 240V outlet connected at different points.
• Based on uses, a step-up 120-volt to 240-volt converter is used, or 2 120-volt supplies can be transformed into 240-volt supplies.

Wiring for 120-Volt Receptacles

• Voltage is split at the panel through the addition of a return path for the line transformer. We can produce a 120-volt circuit through the connection of a wire with a single 120-volt leg and another with a return bus.
• The line wire that carries voltage is black and the neutral wire is white.
• The 120V outlets come with 4 terminals; two are brass and two are chrome. and one is the ground terminal.
• The black line wire is connected with one brass terminal, and the white return wire is connected with chrome.
• For the daisy chain with another receptacle, make the connection of the black and white wire with the other terminals pair, and pull these wires to the load receptacle and connect with the brass terminals pair on that receptacle.
• Receptacles are connected to the ground bar on the panel for safety purposes. The ground wire is bare and connected with green ground terminals on the receptacle.
• If there is more than one cable in the electrical box, all ground wires are connected and configured with the receptacle’s ground terminal.
