Electrical Supplies

Whether you're a homeowner or a professional electrical contractor, Improve Depot offers a huge and diverse selection of electrical supplies at competitive pricing. Plus, we offer bulk discounts on large orders, so be sure to keep us in mind for your most intensive projects. This includes everything from our main categories like dimmer, light, and timer switches, fan speed controls, motion sensors, and outlets to our more niche options like solar power kits and electrical test equipment.

First, we carry a wide range of dimmer switches for your home, office, hotel, or other commercial space. There are many types of dimmers controlled manually or wirelessly, as well as companion and 3-way options for adding other points of access around the room. When shopping for a dimmer, be sure to match your purchase with the lighting load you intend to use it for. There are various dimmers that only work for incandescent lighting, whereas others are specially designed to extend the product life of CFL and LED lighting. Dimmers can save energy while upgrading the comfort in your home or office.

Our timer switches come from some of the best brands in the industry, including Leviton, Intermatic, Lutron, General Electric, Panasonic, and many more. These timer switches control indoor and outdoor lighting, pools system, sprinkler systems, water heaters, appliances, and many other electrical loads. Timers can span a range from a 15-minute off switch to something as comprehensive as 365-day-a-year time control.

Fan speed control is another convenient product to install when you are building or upgrading your home or building. These switches give you complete control over your fans and ventilation products. Many are designed to work with a range of fans, while there are many designed for specific fan brands, allowing for a more customized experience.

For new, retrofit, and renovation builds, you will most definitely need electrical outlets for your power needs. Our inventory includes everything from the most common duplex receptacles and GFCI outlets to niche and modern outlets like USB electrical outlets and hospital grade models.

Light switches are another important electrical product you will need when building or updating your space. We carry a wide range of commercial and residential light switches from 120V to 277V. These light switches come from the top brands in a wide range of colors, styles, and even materials tailored to specific uses (such as heavy commercial applications).

Looking for an easy and hands free way to save energy and automate the lighting in your home or office? Our line of highly advanced motion sensors, including both occupancy and vacancy versions, are the perfect solution. We carry sensors from Lutron, Wattstopper, Leviton, Intermatic, and more. Plus, many of these can be connected with other systems and appliances for even more customized use.

Electrical supplies and equipment are indispensable for any home improvement, commercial construction project, or job site. We offer electrical supplies for any job, however big or small, at wholesale prices. Improve Depot strives to maintain an expansive and helpful selection of products, from small wire management needs to submeters and ballasts to state-of-the-art EV charging stations. These products are as reliable and well-made from top brands, ensuring that your system is incredibly safe.

Regardless of what is required, we stock electrical supplies you need at great prices. Save big with our bundle or pallet purchasing programs.
