Now you should be ready to assist a customer in matching a product to an application. When you meet with the customer, conduct a short interview to obtain the following information:
- Standards requirements—In the Governing Standards section, we looked at different sets of product standards. Once you determine which standards are in force in the application location, you will know which product types can be used for the application.
- Electrical requirements—Product rating information can be found in the product catalog. After selecting a product type, you can match the customer’s requirements with a properly rated product in the catalog.
- Mounting requirements—Determine the customer’s mounting requirements. In the Mounting Methods section, we saw that miniature circuit breakers can be mounted in different ways. Some circuit breaker types offer more mounting options than others do. Go to the catalog to further refine your product selection. If the customer’s first mounting choice is not offered in the catalog, offer an alternate mounting method.
- Accessory requirements—Depending upon the application, miniature circuit breakers can require additional accessory items. Not all miniature circuit breakers offer all the same accessories. Determine which accessories are required, and check your catalog for availability.
Some of the more common accessories that will be encountered are:
- Individual circuit breaker mounting feet (plates)
- Single phase bus bar systems
- Auxiliary switch
- Locking devices to lock a circuit breaker ON and/or OFF
- Special types of terminal connectors
Once you understand the requirements, selecting the best device for the application is a straightforward process.
