](http://www.maretron.com/products/cabling.php)I’ve mostly been working on the rigging lately, but tonight I’m thinking about the NEMA 2000 powertap installation. The Maretron powertap looks like a normal NMEA 2000 T but it has MIDMicro cord coming out of T which you wire up to the DC power system in your boat along with a 4amp fuse (See yellow powertap in the picture). Maretron has a good knowledgebase article on how to do the install but in summary you wire a couple of wires to the 4amp fuse and DC +and the rest to DC –.
I have some other DC wiring I need to clean up that is wired directly off the batteries with no fuses and I don’t want to use a bunch of inline fuses, so I’m going to use a Blue Sea Fuse Block to fuse all these individual items, but do so in a way where I have a single spot to do troubleshooting and add-on future circuits.
I’m hoping to pick up the fuse block tomorrow so I can put in the T which is the first step to getting my NMEA2000 instruments online.
