Generally youll need at least a 8 possibly bigger.
What size fuse for 4 gauge wire. Zero gauge wires rated carrying capacity is 350 amps so a fuse around that size will do 4 gauge at 150 amps is correct. The fuse on the wire is to protect the wire the 70 amp fuse on the amp protects the amp. Put 188A into the top table in this post.
That table tells you that you should have no smaller than 21 gauge wire for your circuit. Personally I would go with the 20 gauge wire and a 25A fuse. If Ive missed anything or left anything out please correct me through PM and I will correct the tables.
What is fuse rating. If it IS REAL 4 gauge wire sure 100A is fine but Im not confident that it is. I think a 60A would be the best choice for now.
Bopo if your wire is accessible just take a ruler and look at the cross section. 4 awg is between 316 and 14. 8 awg is about exactly 18.
Youd be looking at the copper only. The insulation is not a factor. Beside above what size fuse should I use for 4 gauge wire.
4 gauge wire is commonly used as a main power wire so it will be used as an example here. Fuse A must be rated to protect wire B. Any fuse rated at less than 150 amps is sufficient to protect a 4g wire and the vehicle but I generally recommend a 125 amp fuse with 4g wire.
Suggested Fuse Sizes. Wire Gauge Recommended Maximum Fuse Size 00 awg 400 amps 0 awg 325 amps 1 awg 250 amps 2 awg 200 amps 4 awg 125 amps 6 awg 80 amps 8 awg 50 amps 10 awg 30 amps 12 awg 20 amps 14 awg 15 amps 16 awg 75 amps These are the recommended maximum fuse ratings for the corresponding wire size. Using a smaller fuse.
PROPER FUSE RATING TO WIRE SIZE Wire Gauge copper Fuse Rating Comment 22 gauge ga – 24 volt thermostat 10-16 volt doorbell 18 ga. – Lamp cord Low voltage equipment 16 ga. – Lamp cord low volt sound system wiring to speakers etc 14 ga.
15 Ampere amp Common old house wiring knob and tube. As a general rule the fuse size can be determined as follows. LOAD CURRENT x 14 and then round up to the next available fuse.
In the Maxxfan scenario. 4A x 14 56A 75A fuse. In the Maxxfan scenario.
4A x 14 56A 75A fuse. Select fuse or breaker size from column 3 or 4. Read horizontally to the right until the distance is as great or greater than your installation distance.
Go vertically to the head of that column for the recommended wire size. If the motor is required to start under a heavy load we recommend using one size larger wire. If you feel you must fuse the main feed then size the feed wire for all loads including intermittent then fuse to the wire size.
Generally youll need at least a 8 possibly bigger. Id do a 6 on your car that will allow a 50 amp fuse. Wire gauge calculations Wire diameter calculations.
The n gauge wire diameter d n in inches in is equal to 0005in times 92 raised to the power of 36 minus gauge number n divided by 39. D n in 0005 in 92 36-n39. The n gauge wire diameter d n in millimeters mm is equal to 0127mm times 92 raised to the power of 36 minus gauge number n divided by 39.
Wire Size 6-Volt. Alternator or generator and regulator large terminals. Alternator or generator and regulator small terminals.
Gauges fuel oil temperature. Directional signals parking and tail lights and radio. Size of fuse for 10 awg.
- Okay so I recently purchased 20 of KnuKonceptz 10 wire to replace the old 4 awg wire that runs from the battery to the trunk. My question is if the 150A ANL fuse I have for it will be sufficient for the 10 wire as well. Or do I need to upgrade fuse sizes.
1-Between the charge controller and battery bank. To determine the fuse size needed simply matching the rating on the charge controller. For instance if you have one of our 40Amp charge controllers we recommend using an 40Amp fuse.
Work Out The Total Wire Length For The Circuit. You now need to calculate the distance the wiring is going to travel. Once you have this figure you then have to double it.
When calculating wire sizing for DC. Systems the wire length refers to the total length of both the positive and negative wire. With that in mind you do have 5 amperes of leeway.
The correct size of fuse to use in your car is the size that allows the maximum current to pass through that your audio equipment is rated to handle. If you use a fuse that is too large then too much electricity will get through it. What size fuse do I need for 18 gauge wire.
18 gauge wire is a max of 48 amps so I wouldnt go over a 4 amp fuse otherwise the wire would just melt and could cause a fire. Can I use a 10 amp fuse instead of a 5 amp. Circuit length is 50 circuit type is non-critical and correct wire size is 4 AWG.
Click the image below to enlarge. Although this process uses information from ABYC E-11 to recommend wire size and circuit protection it may not cover all of the unique characteristics that may exist on a boat. In its simplest terms you can think of 12 Volts as during 12 units of work.
If youre wire has a 2 voltage drop then the wire is using up 024 volts or units of work. That leaves 1176 volts or units of work left. So if you put a volt meter on your battery and read 12 volts when you put your volt meter on the end of the wire you will.
The chart below charts the gauge wire required based on alternator amperage output and length of wire. Alternator Output Amps Up to 4 ft. 4 7 ft.
American Wire Gauge Conductor Size Table American wire gauge AWG is a standardized wire gauge system for the diameters of round solid nonferrous electrically conducting wire. The larger the AWG number or wire guage the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 40.

Damian Use a 4-gauge wiring kit plus a distribution block that feeds the RD5001 a 4-gauge wire with a 50A fuse and the XD2002 an 8-gauge wire with a 30A fuse.
