How can you determine which terminal to connect a higher current load to when using a relay with both power rated and pilot rated contacts?

To determine which terminal to connect a higher current load to when using a relay with both power-rated and pilot-rated contacts, it is essential to read and follow the certified manufacturer's instructions. These instructions provide specific guidelines regarding the relay's design and intended application, including how to safely and effectively connect loads.

Manufacturers provide detailed documentation that includes information about current ratings, wiring diagrams, and terminal designations, ensuring the relay operates safely and within its specified limits. This is crucial because using the wrong terminal can lead to overheating, damage, or failure of the relay, as well as create safety hazards.

Relying on sources such as warranty information or color coding may not provide the necessary technical specifics required for safe operation. Measuring voltage across terminals is also not a standard practice to determine load connections and does not address the necessary current handling characteristics specified by the manufacturer. Thus, referring to the certified manufacturer's instructions is the most reliable and safe approach.
