What size circuit breaker (fuse) is recommended by the manufacturer to be installed between the battery and the brake controller? 20 amp or 30 amp?

I really don't know. My truck, 2013 Nissan Frontier, had the plug under the dash already so I simply plugged it in and mounted the controller. And, btw..., it works perfectly!

When wiring the +12 (black wire) and ground (white wire) to the brake controller be sure to use at least #14 guage for 1-2 axle applications, and #12 for 3-4 axles at a minimum. This includes both to the controller and from the controller to the trailer connection (blue wire). Make sure trailer connection also has a good ground (white) of at least #14 or #12 guage wire. One or two axle trailers generally require a 20 amp auto reset circuit breaker. Three or four axle trailers require a 30 amp auto reset circuit breaker. These are available for less than $10 at most any auto store. They come with slide on or bolt type connections, either one is fine. Do not use a fuse, it can lead to problems. Use good solder or crimp connectors only. Good luck. I installed this on my older '96 Chevy diesel pickup, which was not prewired except for two unused lines running from the driver's firewall to the rear bumper area. It was an easy hookup. It's an easy to use controller that works great on my large two axle travel trailer. You should be pleased with it.

I used an 80amp blade fuse and holder sold for an automotive audio amplifier. I bought mine at Wal-Mart (It was under $20) as I needed it right away, but Amazon probably has it too. I cut the positive battery cable (with a hacksaw) and the fuse holder was installed in-line.

I would go with a 15. 10 blows too often, 20 really isn't safe enough. Try and use a "slow blow" or "slow burn" fuse since anything amplified will power spike.

One is AC and the other DC. The 30 amp fuse is on the AC supply side and the 55 amps is what is provided to the DC BUS (I'm not an expert but a 120V/30A source could provide up to 330 AMPS DC) Check out this website for more info...http://www.batterystuff.com/kb/tools/ac-to-dc-amperage-conversion-run-through-an-inverter.html

the whole block is rated at 100 amps, so the wire gauge and fuse you use should be determined by the load you want to put on the block (up to 100 amps) and the length of the wire run to the battery from the block. 8 gauge would be adequate for a short run, 4 gauge for a longer run up to 20 feet or so.

Adding to what others have said, I would go a little higher than the max Amp rating but also limit according to your battery. My unit feeds anything from 225Ah to 360Ah battery banks. If you use the 10-15% of Ah capacity rule then a 30A fuse is fine. I would have to swap in a much smaller fuse if charging a smaller battery bank and of course limit the PV power coming in or connect it to a smaller array.

I can tell you that they provide a 30 AMP fuse to protect the circuit. Hope that helps!

If all accessories are run through this panel the one additional fuse is at the battery. This fuse should be large enough to handle the load of all accessories on at the same time.

I have no idea the breaker size. Battery wise, I have a large deep cycle trolling motor and it works great. The charge gauge is very handy. I do use a bungee cord to keep the top attached better. Overall, for the price, good value and quality. Better than I expected.

The instructions don't say you should, I never have in 20 years of use. Some I know have used a 30 amp fuse. To be safe you probably should. One of those things I am to do but never do.

20 Amps is a max load for a 12-3 and if your going over a long distance the resistance will increase more. If it's new installation I would use 10-3 and then not have to worry. The cost difference is small.

probably 20 or 24 gauge wires but I didn't use the cigarette connector. I used a 12 gauge wire and run it directly to the battery and used a 20A fuse.

The documentation says: Suitable for use on a circuit capable of delivering no more than 10,000 rms symmetrical amperes, 120 volts maximum when protected by a 20-ampere circuit breaker rated 120 volts minimum. The interrupting rating of the fuse or circuit breaker shall not be less than the available fault current.

Tripplite's website shows that at full load it consumes 200 amps. If you plan on using it fully loaded, you may want a slightly larger fuse than 200, or use a circuit breaker. Fuse size also depends on the size and length of wiring you use to connect it to

you are running on a 12 volt system I use 15 amp fuses, but I check my draw and output accordingly and don't push more than I need or run more circuits and have switches, like 6 flood lights and a separate circuit for appliances/tools, depends on your 12 volt battery, a trolling motor steady draw or a faster high output for tools with a short draw.

i got the R300x4 the recommended fuse is a 50 amp...on the R250x4 a 50 amp is also recommended

I put in a 40 amp breaker for this unit, but have th jumpers set to 5000 watts and have never needed to run it on high in my 3 car insulated garage, so a 30 amp breaker would have worked.
