that is good dude
A circuit breaker does not have a wire fuse in it.
An easy way to do this is to get yourself an "Ugly's" book. Its a small electrical reference guide for circuit protection, (sold at Home Depot & some electrical supply houses). Buss, and other fuse makers usually can supply you with a similar guide.You will also need to find the right size Motor Starter & Overload Heater within the Motor Starter. But to answer your question;To select wire, or fuse/breakers for a Motor Load, you need to look at the Motor's FLA (Full Load Amps), take that number and multiply it by 1.25 (this is a 'rule of thumb' & not Absolutely necessary),-Now you have the maximum amperage that the motor will draw under NORMAL OPERATING CONDITIONS. Go to the NEC section on conductors (i.e. wires) and find a suitable gage wire (in the 75 deg column) and find a wire that will handle the amount of current the your load requires.Now find a fuse or breaker that is permitted for the WIRE, not the load.For example: if you have a motor that draws 10 amps (full load), you might use 16 gage wire, 16 gage wire may be rated for 20A, use a breaker, or fuse rated for 20A.Its always best to use the lowest temperature column in the NEC book because you have to account for all connections in the circuit (i.e. lugs, crimps, spades, terminal blocks, etc.)YOU NEED TO SELECT A FUSE, OR BREAKER BASED ON THE WIRE SIZE, NOT THE LOAD ! !
Because those metals have a high meling point, so it's easier and safer to use fuse wire which melts at a lower teamp.
Use a 20 amp fuse or breaker.
The only time that fuse holders gets hot is when there is a loose connection between the fuse holder and the wire connected to the holder. If this is happening remove the supply voltage from the circuit that the fuse holder is in. Remove the wire from the holder. Cut the burned end of if there is enough wire and re install. If not enough wire, use a wire brush to get the oxidation off of the wire. Apply a coating of anti oxidation compound on the wire end and then re install into the holder. Tighten the wire into the holder very tightly. Check the spring clamping pressure of the fuse end of where the heating occurred. This spring clamping pressure is important for low resistance conductivity. If the fuse feels loose when installed change the fuse holder for a new one.
The correct size fuse needed is based on the size wire used in the circuit. The size wire needed is based on the load that will be applied to the circuit. 1. AWG 14/2 wire = 15 amp fuse 2. AWG 12/2 wire = 20 amp fuse 3. AWG 10/2 wire = 30 amp fuse 4. AWG 8/2 wire = 40 amp fuse
NO. Usually the positive wire will have the fuse.
The wire may not melt and break if an unsafe current is produced.
The 15 amp fuse.
A circuit breaker does not have a wire fuse in it.
Fuse wire is designed to open under over current conditions. Just like a fuse.
Bulb, wire, fuse, etc.
Every fuse is rated for some certain current. The rating is the maximum currentthat can flow through the fuse before the wire in it gets so hot that it melts andopens the circuit. (In the arcane jargon of the high-tech world of engineering,especially electrical, this event is described by saying that the fuse "blew".)The thinner the wire is, the less current it can conduct before the wire melts.The thicker the wire is, the more current it can carry before the wire melts.So, the wire you select for your fuse completely depends on the current forwhich you want to rate your fuse, and above which you want it to "blow".
yes there is a fuse in the fuse box. the wire will lead to it or to the ignition switch. But the fuse to amke the hot wire hot is in the under dash mounted fuse box.
Isolate the cicuit in question, or turn off power altogether. Remove the burned/fused section of the fuse wire in the fuse carrier and replace with the recommended fuse wire. Turn power back on.
Metal with a lower melting point is preferred for fuse wire to reduce the risk of fire.
Take off the right side panel, on the left side of the battery you will see a red wire. This is connnected to the starter solenoid, trace along the red wire till you find a plastic fuse holder open it and you will be able to see if the fuse has blown.
