End feed power to nmea2000?

[Tintin]

Am wiring tiday so quick replies apprecaited.

I have three nmea2000 T's and three nmea2000 devices.

Is it possible to end feed the power instead of one terminator, or do I need to get another T?

Do i actually need to power it if all the devices (garmin vhf, ais and plotter) have their own power feeds?

You need terminators at both enda. Have not seen terminators with powersuply cable.
If all your instruments have their own supply I wold think that you can do without

You must seperately power the N2k network via a T with its own fused power supply (3a assuming you are using standard light cable) , you must have a terminating resistor each end of the backbone.

Lowrance do a power connector with built in termination resistor to end feed an N2K network. It sounds like you don't have any backbone cable, just the three T's, so it would probably suffice (be prepared to pay a fairly hefty N2K tax though)

The NMEA 2000 backbone does not need power supply to operate.
The Power supply into the backbone is a handy way to provide power to components with small power needs, my i70 displays take bower of the back bone - but my plotter has got it's own

The OP wrote that he would install on june 8th, maybe he can update this thread ?

Nothing powered up yet - it is a major refit from batteries onwards.

For the N2K I have ordered another tee for th power cable to go into and my or may not use it - will try without first and report back then - extra £20 but compared to the overall spend yada yada yada
