Can you replace a 30 amp fuse with a 15 amp fuse?

Not a good idea. The 15 amp fuse will be protection a #14 wire which is rated for 15 amps maximum capacity. By changing the 15 amp fuse to a 30 amp fuse you would then be allowing 30 amps maximum capacity on a #14 wire. By doubling the load the extra heat generated on the smaller wire could be enough to melt the insulation from the wire and that could cause the wire to short out. If the wire shorts out inside the wall it means the removal of the wall board to replace the wire to restore the circuit to an operational condition. The proper wire sizing for a 30 amp fuse is, #10 copper wire with an insulation rating of 90 degrees C.


How do you choose the right fuse for the job?

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

Can 600v wire works 30 amp fuse?

What size is the wire? AWG 10, 600V is rated for 30 amps. Any AWG less than 6 would also be ok for a 30 amp circuit....


Can a 30 amp fuse replace a 20 amp fuse?

NO!!!! The fuse is your safety device. Never replace a smaller fuse with a larger fuse.Another answerPeople who have done that in the past have burned down their homes. Changing from a 20 amp to 30 amp fuse puts 50% more current through the wire, overheats the wire and can result in fire. Don't do it. As the above post explains, the fuse is your safety device.To Ad:The above answers are dead on. Remember the fuse protects the wiring from overheating and catching on fire. A 20 amp fuse is used on 12 gage wire and a 30 amp fuse is used on 10 gage wire which is must larger. Never mix them up.To Ad: actually if you people wouldve took some kind of electical class its better to put a bigger fuse.. you just do not need to double the size.. if you got a 20 put a 30 in it it want blow.. if you put a 40 then you will have problems...


1998 jeep Cherokee blown 30 amp Maxi fuse for the starter Turned the ignition switch nothing replaced the 30 amp fuse and all works well why did the fuse blow short somehere?

sometimes just extended use will cause the fuse to blow, but you might check your ground wires or just see if there is an open or pinched wire that may be rubbing your chassis or touching another wire..-Shocker

Not a good thing to do! If you are blowing 10 amp fuses, you have a problem with that circuit. Putting a 30 amp fuse in its place can do more damage.
