Electrical Ballasts
Electrical Fittings are the products, which are used for fitting various electrical devices like switches, fans, wires, tube lights etc. These components are available in a wide variety of shapes and sizes and materials. Before selecting electrical fittings for any hazardous location, the exact nature and concentrations of the flammable materials must be considered. An electrical fitting that is safe for installation in an atmosphere of combustible dust may not be safe for use in an atmosphere containing flammable vapors or gases. Thus, electrical fittings are specifically designed considering various hazards.
While buying these fitting items a buyer must always keep in mind the quality of the component, the price of the item and credibility of the supplier. China, Hong Kong, Taiwan and Germany are the leading manufacturing countries of electrical fitting components. These fitting components can be classified as follows:
* Brass
* Copper
* Stainless Steel
* Plastic
* Thermoplastic
The various types of electrical fittings are:
* AC Power Connectors
* Cable Protectors
* Cable Clamps
* Cable Ties
* Cable and Wire Accessories
* Electrical Lugs
* Electrical Dimmers
* Electrical Ballasts
* Electric Switch Plates
* Electrical Conduit
* Electrical Grommets
* Electric Meters
* Electrical Plugs
* Electrical Busbar
* Fuse Holders
* Junction Boxes
* Power Strips
* Terminal Blocks
The materials used for making electrical fittings cover a wide range.. more

DC Power Cords
DC Power Cords
Also known as DC power cables, DC power cords are a kind of electrical cables used for connecting two DC devices or a DC device and a DC power source.
Types of DC Products
There are different types of DC products manufactured and available in the market. These include:
* DC power supply cords: This is used for connecting a DC power supply to a device that uses DC power. These power supply cords are available in varying lengths and can have either two or three prongs.
* DC power extension cords: This is used for extending the length of a standard DC power cable. These power extension cords have a plug on one end and one or more sockets on the other.
* DC power adapter cords: This cord has a different type of plug or receptacle on each end.
DC Power Cords Specifications
There are certain important specifications that must be considered while selecting DC power cords. These are:
* Cord length: It is the measure of the cord in meters or feet and includes both connectors.
* Wire shape: The shape of the wire can either be round or flat.
* Jacket material: This will include polyvinyl chloride (PVC) and rubber. While PVC is mostly used indoors, rubber jackets are used for dry and damp areas.
* Maximum cable temperature: This is measured in degrees Fahrenheit or degrees Celsius.
* Rated current
* Rated voltage
Approvals and Certifications
DC power cord manufacturers can take approvals like the UL Mark and the CSA Mark. Underwriters Laboratories (UL): It is a non-profit organization that undertakes various tests of components, systems, and materials according to its published standards for safety. Products receiving the approval of this organization bear a UL Mark.
Canadian Standards Association or CSA is an organization that tests these products on various parameters. Products that get the approval from this organization after meeting specific safety and performance levels bear the mark of the organization.
American National Standards Institute (ANSI) is another organization that provides certifications and approvals to manufacturers.
