Q

In an NMEA 2000 device, a load equivalence number (LEN) of 1 is equivalent to how much current consumption?

🔍 Key Concepts

• NMEA 2000 power budget and how devices share a common 12V bus • Definition of Load Equivalence Number (LEN) in the NMEA 2000 standard • How LEN converts to a fixed current value so installers can add up loads easily

💭 Think About

• If you add up 4 LENs on a small NMEA 2000 network, about how much current should that represent, and is that a practical, easy-to-use number? • Which of the options would make it simplest to estimate total current draw when you have many devices, each with an integer LEN value? • Think about a realistic current draw for a small NMEA 2000 sensor (like a temperature or depth sensor). Which value per LEN makes sense?

✅ Before You Answer

• Make sure you understand that one LEN corresponds to a fixed current value, not a range • Check which option would give reasonable total currents when you imagine 10–20 LENs on a modest network • Verify that the chosen value is large enough to be practical, but still small enough to give useful resolution when summing many devices
