A contactor is an electrical device that is widely used for switching circuits on and off. As such, electrical contactors form a subcategory of electromagnetic switches known as relays. A relay is an electrically operated switching device that uses an electromagnetic coil to open and close a set of contacts.

A lightbox is a window that can convey various pieces of information in a way website visitors can’t possibly miss. It’s proven to be an effective way to get them to sign up for emails, newsletters, or other notifications from your site. A light therapy box mimics outdoor light. It’s thought that this type of light… Read More »SPOT LIGHT BOX

Metal boxes’ strength comes in handy when mounting especially heavy items like ceiling fans or heavy light fixtures. Metal boxes can also be used with Romex or NM wiring if desired, though special precautions must be taken to ensure proper grounding. Metal back boxes are commonly used in commercial and industrial settings. They are robust, durable, and… Read More »METAL SOCKET BOXES

PVC has become the standard electrical box material, especially for DIYers. Lightweight and easy to work with, many of them also come with built-in clamps for wiring. Though PVC can melt when overheated, it does not conduct electricity like metal does. While PVC can melt when overheated, it does not conduct electricity like metal. Use plastic boxes… Read More »PVC SOCKET BOXES

Electrical employees run or pull wire throughout a worksite. This involves pulling at one end of the run and feeding at the other. Wire is pulled through chases, conduit, or knockouts to get from the electrical supply to the final destination. The wire puller is a machine designed to perform the task of transporting wires from one… Read More »Wire Pull Strap

The 3-pole breakers are used for three-phase circuits where there is L1, L2, L3 and N wire. Normally, any residential users may use 120/240V single phase system, therefore they’d need 2-pole. The difference between two 120V wires is 240V, that’s why the voltage rating is 240V. There are three basic circuit breaker varieties: standard breakers (which… Read More »BRANCH BREAKER 3P

A terminal block consists of a modular housing with an insulated body that secures two or more wires together. Terminal blocks—also referred to as terminal connectors, connection terminals, or screw terminals—are used in a wide array of applications where electrical systems need to be safely connected. A terminal block is a modular, insulated housing that connects… Read More »Terminal Block

Double-pole breakers have two hot wires that are connected by a single neutral wire. That means if there’s a short circuit on either of the poles’ hot wires, both trip. These breakers can be used to serve two separate 120-volt circuits or they can serve a single 240-volt circuit, such as your central AC’s circuit
