A power socket is a device to which electrical devices can be connected to receive the electric current required for their operation. Connected by a system of cables to a power source, usually an electricity generation facility operated by an energy production company, it generally has no moving parts. Instead, it contains metal strips which make contact with the prongs of an electric plug inserted into the socket. It’s through these contacts that the electric current is transmitted.
Two-pronged outlets: feature two long connection slots and provide an ungrounded connection. The three-pronged version: adds a ground pin and an extra vertical slot to help prevent electric shock from loose wiring.These are also the cheapest types of electrical outlets on the market and easy to install or replace. At the same time, these can also be prime candidates for an upgrade in the near future. For improved safety and efficiency, it can be a prudent idea to choose more modern alternatives on this list.
These electrical outlets support a larger power draw than the previous type. Building codes recommend installing 20A outlets for some appliances, such as large kitchen gadgets, that need more power to function.You can tell these apart from the 15A version by looking for a small horizontal slot alongside the vertical ground slot. These may even be a perfect fit for some washing machines, dishwashers, and space heaters.
Large appliances like air conditioners, air compressors, and hobby shop equipment need even higher levels of power. For such uses, this is the type of electrical outlet to choose..Before installing these 20A, 250-volt outlets, you will need the proper circuit in place. 250-volt outlets need a double-pole circuit breaker installed in your main panel, a job best left to an electrician. Look at the power specifications of the appliance that you plan to use and choose accordingly. Some appliances such as wall ovens and electric dryers might need even more power than these outlets can provide. For these types of cases, you might want to take a look at 30A or 50A outlets.
Building codes in most places have now made it mandatory to use tamper-resistant outlets in new construction. These types of electrical outlets utilize a built-in physical barrier to prevent the entry of foreign objects. The internal shutters open only when you insert a two-pronged or grounded plug. If you have children at home, this can be a safe choice. Even if children try tampering with these outlets by putting something other than a plug in, there is no shock hazard.
If there are appliances or lights you want to keep plugged in all the time even when they aren’t running, consider switched outlets. The unit integrates a socket and a connected switch. Use the switch to control the power to a connected appliance without removing the plug from the outlet. (You do not need a fresh electrical box or any extra wiring to install these.)
