Battery Box July 26, 2014, 09:02:48 pm Yahoo Message Number: 147624Hi Cliff; You have the idea right. The wires going out into the battery box are numerous and stiff, so that make it hard to slide the battery tray in and out. It is on my to-do list (soon) to take some of the room out of my vanity cabinet (TKB) shorten and dress the wires onto copper buss bars, and just have flexible welding cables go to the batteries. The 100 Amp breaker would go inside. The junction wire between the batteries would remain the same. I collected the buss bars before the copper prices went crazy, and a professional welder friend provided the cables (OO). I have just a small 400 watt inverter, that I want to locate at the back of my vanity cabinet also. By putting in full extension drawer slides, I hope to be able to fit T-145's, and be able to check their water levels easily. I hope you are comfortable working on heavy copper wiring. L.D. used latex caulk, painted black. I suspect there are rubber grommets under all the goo. Hope this helped RonB

Re: Battery Box Reply #2 – July 27, 2014, 12:46:37 am Yahoo Message Number: 147628For the typical 105 deg C insulation, the ampacity for 2/0 is 280 amps (2/0 is seriously big wire). 4 AWG is good for about 160 amps. Check this chart for variations required by a particular installation, with might require bigger sizes due voltage drops, bundling, and temperature: http://www.westmarine.com/WestAdvisor/Marine-Wire-Size-And-AmpacityEric Greenwell [lifewithalazydazerv] wrote, On 7/26/2014 6:26 PM:

It depends on what peak amperage you expect. The water pump maybe 12 amps, lights a few more amps. I don't know how many watts your inverter is. The distance is so short, you can get by with smaller wire. If you don't run a microwave sized inverter, #2 would be fine. RonB
