[QUOTE="Bob Landry, post: 234128, member: 7025"] Electrical component manufacturers tend to under rate the load of their parts. I would add a little bit for those. The lighter plug is going to be rated for 10A(most are) and you may want to plug in a spotlight. I came up with an estimate of 17A for the load. No one ever went wrong using bigger load, so I would call it 20A. 13' distance is actually 26, since you have to count both directions. You want to figure for a 3% voltage drop minimum. #10 will give you a little under 4% which would probably be OK for your application, since all of your stuff isn't going to be rumming at the same time, but for a couple of bucks difference in price, #8 will put you a little under 3% which is where I would rather be. That covers the feed to the fuse block. Then you need to fuse the individual circuits for the load that they will be servicing. I personally use #8 for all of my main feeds, except the TM and it gets #6. Also use AWG wire, not SAE, it's a little larger.The idea is to keep the heat down in the wire. [/QUOTE]
