What size fuse do I need for 0 gauge wire?
zero gauge wire’s 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!
How do you determine fuse size for a wire?
Example: For a 4 AWG single wire outside an engine room, maximum fuse amperage is 150A. B Calculate MINIMUM FUSE AMPERAGE by multiplying product amperage rating by 125%. Minimum fuse amperage provides more protection for the wire but may result in nuisance blows. Example: 80A x 125% = 100A.
What fuse to use for gauges?
start with a 5 or 10amp fuse which ever your power gauge wire is smallest.
How big of a fuse do I need?
For your fuse to do its job correctly and protect your wires, it should be rated about 1.1 to 1.5 times the rated current value. The fuse size should be based on the SMALLEST wire (largest gage number) in the circuit.
How do I choose the right fuse?
In order to select the right amperage of the fuse, you first need to know the full-load steady-state current of the circuit at an ambient temperature of 25º C (68º F). Once the current value is determined, then a fuse rating should be selected as to be 135% of this value (taken to the next standard value).
What amp fuse do I need?
Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). For example: 13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron.
How do you size a 12v fuse?
Find the size of fuse by multiplying the amps required by the device (2) by 1.5. 2×1.25 = 2.5 then we will round up to the nearest fuse size (in multiples of 5 amps) which would call for a 5 amp fuse.
Can I use a bigger fuse in my car?
Never replace a blown fuse with a higher-amp fuse. Always replace the fuse with one with the specified amp rating. You may install the next-smaller-rated fuse to get you by in a pinch until you can purchase a replacement.
How big is the fuse on a zero gauge wire?
zero gauge wire’s 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!
What’s the safest fuse for a 0 AWG wire?
The fuse on the wire is to protect the wire, the 70 amp fuse on the amp protects the amp! If you only have one amp on the power wire and that amp is fused at 70A you only need a 70A fuse in the 0awg wire. A 70A fuse is the safest size fuse for the application, but anything between 70 and 350A will protect the WIRE.
How do you determine the fuse wire size?
The fuse size should be based on the SMALLEST wire (largest gage number) in the circuit. For those of you who want to get right down to business, let’s not waste any more time, here’s how you’d go about calculating fuse size correctly in 3 simple steps:
What is the function of a fuse wire?
The main function of a fuse is to protect your wiring, but in order to do so, you’ll have to get the right fuse wire size from the start, too low and it’ll blow, too high and you’ll end up doing damage to the whole circuit!
