I know these questions have been asked 100 times, and I used all that info to get a good idea, but I figured asking a few dumb questions beats finding a pile of ashes where my truck used to be.
I'm mounting a 1100 watt (2200 watt peak surge) inverter under the glove box and want to make sure all my wire and fuse sizes jive. I was planning on using 4 AWG, based on the peak surge of the inverter and approx wire run length (based on wire gauge charts). Is 4 AWG sufficient or should I go to 2 AWG or something else? (also when figuring the length of run to compare to the charts does that include from negative to ground, I assumed it was calculated from the positive length only?) Also, what size fuse would I need? For peak surge I would need something like a 185 amp fuse, is my math right? Do they make fuses in that size, where would I find one, and will it work with size wire I'm considering? Should I put in a relay and a switch so that I can cut the power from the battery, or is that overkill since the inverter has a power switch?
I'm also going to add some LED lights to the bed, but will size the setup for two 55 watt lights in case the LEDs suck I can change them out without re-wiring. I plan on using a fuse tap with a 1 amp fuse (but will change it to a 10 amp fuse if I decide to use the 55 watt setup down the line), to a 10 amp 12VDC rocker switch, to the bed with 14 AWG. Will 14 AWG be ok since the run from the fuse to the bed is a little long? Does that whole setup sound about right?
I have learned so much just browsing around this site, and everyone is really helpful.....THANKS!
