Sierra PC51070 NMEA 2000 Power T Cable — 3 ft
The Sierra PC51070 is a 3 ft NMEA 2000 Power T Cable used to connect a 12V DC power source to an NMEA 2000 network backbone. Every NMEA 2000 network requires a dedicated power connection to operate, and the Power T Cable is the correct fitting for that connection — it taps into the backbone via a standard Micro-C T-connector and routes power from a fused 12V supply to the network. Gold-plated copper alloy terminals, 18AWG conductors, and an IPX7-rated waterproof connection ensure reliable power delivery in demanding marine environments. Fully interchangeable with other NMEA 2000 certified products.

Parts Desk Insights
The PC51070 is an essential component that every NMEA 2000 network needs — without a power connection, the backbone and all devices on it will not function. It’s the part that’s easy to overlook when a customer is focused on buying extension cables and drop cables, so it’s worth confirming they have one in their order. Always recommend connecting the power cable to a fused 12V circuit — NMEA 2000 networks typically require a 1A fuse. To complete a network installation, pair this with the backbone extension cables — Sierra PC51000 (2 ft), Sierra PC51010 (3 ft), Sierra PC51020 (6 ft), or Sierra PC51030 (12 ft) — and drop cables for individual devices: Sierra PC51140 (2 ft Drop), Sierra PC51160 (6 ft Drop), and Sierra PC51170 (16 ft Drop).
