Information on Buying Twist Lock Plugs & Receptacles

A design invented nearly a hundred years ago, twist lock receptacles are a classic device used in wiring to provide extra safety and reliability to many appliances. From light fixtures to equipment and hardware, having a secure and stable connection to power is essential to ensuring proper function, as well as preventing potential hazards and faults. They work pretty much exactly how they sound - once a plug is inserted into the socket, it twists and interlocks the blades with the receptacle. This coupling makes the connection more reliable, providing extra security in tougher environments.

Different volts available.

As with any electrical product, there are different voltages available to meet your needs such as 120v, 208/240v, and 277v. When choosing the right option from our selection of twist lock receptacles, you will need to know this factor before you start shopping since it can lead to electrical issues down the road if you choose the wrong voltage for the power used.

Choose the right amps.

Aside from voltage, the other crucial figure to consider is the amps. We offer both 15 and 20-amp options to meet your needs with ease.One way of determining which one is right for you is to consider your wiring. For instance, a 14-gauge wire is typically protected by a 15-amp circuit breaker whereas a 10-gauge or 12-gauge wire is in need of a 20-amp circuit breaker. This can help you choose the right amps for the setup.

Check the ratings and certifications.

There are certain ratings you want to check for when shopping receptacles.For starters, some options are NEMA standards and feature the specs of the item on it for easy viewing of important information. There is also the matter of UL ratings for flammability. Make sure you consider these factors while shopping.

These twist lock receptacles also carry features such as solid one-piece brass contacts for exceptional conductivity and reduced heat rise, heavy duty terminal screws, grounding screws included in most models, and more. Choose from a range of options and find a high-quality solution for your needs today.

Perfect for commercial and industrial applications, they will allow you to work with confidence, knowing your hardware or light fixtures will remain steady and perform when you need them all day long.

With ordinary receptacles, plugs that are pulled even slightly can come clean out, disconnecting your hardware from its power source instantly. This can cause a lot of problems ranging from simply inconvenience to outright danger. Having your equipment secured by a powerful twist lock receptacle is important for ensuring you complete your work without issue. Whether you are using a simple light fixture, power tool, or other equipment, you will appreciate the extra level of security every day. Many outlets also come with integral strain relief, enabling them to ease the burden of heavy pulling to prevent damage and potential problems.

We have the best selection of twist lock receptacles that will help you get the perfect option for your space. 120 and 277-volt options are available, in both one and two-level models. Our products can match any NEMA standard connector, allowing you the freedom to use whatever hardware you desire. Take the stress and hassle out of connecting your appliances, tools, and lighting to a power source by using industrial strength receptacles that will keep your connection secure every minute of the day.

If you have any questions while shopping with us, please reach out for assistance. Our team of specialists is always happy to help you find the best solution for your needs
