If you're going to use Aluminum SER (Service Entrance Rated) cable, be advised it's thick and harder to work with than copper but available at your big orange box store. I spent a lot of time looking into this and without getting technical, I went with 1/0. Google "Allowable Ampacities of Insulated Conductors" and remember that you can't necessarily look to the 90 degree column and that inspectors will re-rate, or reduce the allowed amperage based on other factors. For my short run to me it was better to go bigger and be sure.

For 100A you need at a minimum #1 AL or #3 CU. Aluminum is a third or less than the cost of copper. Go with AL. Note: This is based on 75C temp rating, if 60C is used then the next size larger wire is needed. Also, For those sizes, you'll probably want to call a local electrical supply. You don't usually or always find those in home stores. Especially #3 CU. Now if you scale back to 75A or 90A (ask your local inspector what's allowed), you could use 2-2-2-4 aluminum mobile home feeder, which runs about $1.6x a foot more or less.

#4 copper or #2 aluminum per NEC Table 310-15(b)(6). Note that sub-panels must have the neutrals and grounds completely separated, with the neutral bus isolated from (not bonded to) the steel enclosure.

It depends on what you are connecting to that breaker as to the load it will pull. Check your instructions for the item that you are going to connect to the breaker as to what wire is required for the load it will pull.

Howdy William. 4/0 AWG is the minimum for this inverter but the length of wire will dictate the gauge needed for efficient power transfer. Using a fine copper wire cable is key, as is using the proper fuse recommended by the mfg. for the size inverter. I used a high quality heavy duty 0 AWG ultra fine copper wire 10' jumper cable and a 80 amp class T fuse for my SW600. Hope that helps...

I think 16 guage is the biggest wire it recommends. I would get something more heavy duty.

The Titan N-120 is supposed to be a dual-pole 60 amp breaker, but mine is hooked to a dual-pole 50 amp and it works fine. You have an N-160 which recommends 4 or 6 gauge wire and a dual-pole 70 amp breaker. What size are you trying to use?

Its 100A max input which would point toward 6gauge if you want to provide full current capacity. I however used 8guage as I'm only pulling maybe 60A max.

I used size 4 for all my solar needs panels to controller to batteries from there to fuses to inverters. mite be over a little. But I don't have to worry about wire size. and it fits fine on my controller. I am not loosing any power due to that size. and I had problems with this controller!

Honestly I don't know much ... I have a 1000w monoblock Kenwood class b hooked up to it

This is a more complex problem than it would seem. I tend to use overkill when sizing wire to a given load. In addition, a friend replaced all of my fixtures original quartz halogen bulbs with LED's that draw less current. And generally speaking, it is not just the load in amperes, but the length of the wire run in feet that determines the wire gauge needed. I would suggest that you employ someone with knowledge in electronics to size and determine your layout. This is especially true if your layout is complex and heavily loaded. I wish I could be of more help, but I have to hire an electrician. Good luck! This is a more complex problem than it would seem. I tend to use overkill when sizing wire to a given load.

It was a close fit from what I recall on my inverter setup. I used the 0 AWG (.325) wire.

I would use a 10/3 cord. For every 100 feet you should use 1 size bigger gauge.

0 Gauge wire should be used!That is what is ran to my Brutus.At the very least a deep cycle battery (fast discharge) should be used!My total system wattage is 5400& I use 0 to each amplifer!The more voltage the better!!!Don't Skimp Out!

Judging from the wire size, I would take a guess less than 5 amps like GB suggested. The wire looks like it's in the 16 to 18 gauge area.

Yes you do, it will not accept larger wire. If you have a different size wire, we offer these in other sizes, what size wire do you have?

I personally use monster 14ga on mine. There is really no need to use anything larger than that. Unless you just want the awesome look of overkill. I would also recommend the use of banana plugs, as the location and angle of the binding posts make it difficult to thread bare wires into.

1200-1300. U might want to cut in port holes if ur looking for that big boom
