When Only One Half Of An Outlet Works

The efficient functioning of all electrical outlets is essential to ensure a trouble-free life for homeowners. But electrical problems are pretty common, and outlet failure is something that no homeowner can avoid. A bad connection, outdated wiring, or a tripped circuit breaker can cause a malfunctioning outlet. But there are instances where only half of an electrical outlet works and the other one doesn’t. It can happen for multiple reasons, and it is wise to call an electrician to look into the issue.  

Here are a few possible factors that might have led to this situation:

Half-hot outlet

It can happen due to a switched or half-hot outlet. It is a type of duplex outlet with space for two receptacles and is commonly found in bedrooms, landscape lights, living rooms, or in areas that use floor lamps or nightstand lights. They allow plugging in two devices simultaneously. In the case of half-hot outlets, where half of the switch is always ready to provide electricity permanently, and for the other half, there is a wall switch just like standard outlets. It facilitates the easy operation of lights without the need to turn the switch on and off multiple times. If only one half of the outlet is working, check for a switched outlet.

Wiring issue

For a standard plug or switch, wires are curled around the screws before tightening them. You can remove the outlet plate and take out the receptacle from the box to see if the wires have been appropriately wrapped or not. There is a chance of a loose connection if the wires have been backstabbed instead of wrapping them systematically. If you find an issue with the cables, it is advisable to call an electric company to fix it.

Wire connectors are not used properly

If an outlet stops functioning as effectively as it should be, incorrect use of wire nuts can be one reason. Wire connectors are fasteners used to connect multiple electrical wires tightly in a box. They help prevent wires from coming in contact with each other. An electrician can connect the cables as required to resolve the issue.

Types of wires used

Wrong use of wires can also lead to this issue. Generally, wires are made of aluminum or copper. It is advisable to use copper wires as they are sturdy, safe, ductile, and has high conductivity. While aluminum is brittle and has a high resistance to electricity that can burn up the wiring due to heat build-up inside the outlet. Therefore, it is essential to use the right type of wire for the outlets. 

Working with electricity involves a considerable amount of risk, so it is better to avoid doing DIY repairs. If you have any issues with the outlets, wiring, electrical installation, or any other electric problem in the house, it is always advisable to call an electric company. Their electricians have the expertise,  tools, and equipment to safely and perform any electrical task.
