A number of companies buy and sell used machinery on a regular basis, especially when they have equipment that isn’t used or needed anymore. This is a great way for small and medium businesses to procure expensive items at affordable rates. They can also improve cash flow and save on overheads when they sell surplus equipment online.
Of course, you need to be careful when you buy certain goods online, such as electrical equipment and accessories. For any industry or business, regardless of scale, selecting the wrong type of electrical material or buying low-quality parts can lead to a lot of trouble down the line.
Here are 7 things to keep in mind when you’re looking to buy surplus electrical equipment or looking for used machinery for sale in India:
- Input/Output Voltage Ratings – When you buy any electrical device, it’s important to be aware of the overall voltage rating of the equipment as well as the power source you are using. This determines whether the equipment is suitable for the application. Buying electrical fuses, circuit breakers and transformers with the incorrect voltage rating can increase the risk of arcing, short circuits and electrical fires.
- Continuous Current Ratings – For many kinds of electrical components, such as circuit breakers, a continuous current rating can tell you whether the device will perform properly in different environments. This rating is listed in Amperes, and represents the continuous current that can be carried by the device when it’s used in the precise ambient temperature in which it was calibrated.
- Short-Circuit Current Ratings – Also known as SCCR, this rating defines the maximum short-circuit current that a certain electrical device, assembly or component can handle safely. The short-circuit current rating for an electrical panel or other assembly can be calculated based on the SCCR for each individual component, so you need to ensure that you select components with the proper rating.
- Electrical Current Frequency – While selecting circuit breakers and other electrical equipment, you also need to pay attention to the current frequency at which they are designed to operate. Along with the Ampere rating and frame size, electrical current frequency helps to determine the highest current that your device will be able to handle without a need for derating or specific calibration.
- Maximum Interrupting Rating – Also known as breaking capacity or interrupting capacity, this rating defines the highest amount of fault current that fuses, circuit breakers and other electrical devices can safely handle without arcing or damage. You need to select devices with an interrupting rating that is equal to or higher than the maximum fault current delivered at the location where these are used.
- Other Safety Concerns – The safety of any electrical device depends upon numerous factors. These include everything from current ratings and breaking capacity to the location, temperature and environment where they are installed and used. Proper design, construction, setup and maintenance also make a difference, so take all these considerations into account while selecting any equipment.
- Quality Assurance – Before buying any electrical goods or materials, you should always check whether they have been tested for health and safety, long-term functionality and performance, etc. Make sure that the seller can provide you with proof of quality assurance and compliance, such as ISO certification, and whether spare parts and components are easily available should you need them.
When you buy used or surplus electrical goods online, make sure to look for reputed sellers who are willing to provide you with the details mentioned above. And if you’re looking to sell online, it helps to include relevant information in your product description, so prospective buyers can easily decide which items are right for their needs.
