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.

∙ 12y agoIf you are talking about a breaker or fuse, the answer is no. The breaker ensures that too high a current isn't permitted to flow in a circuit where the devices may fail catastrophically. For example, if your 20 amp circuit used 12 AWG wire and outlets, they would not be protected adequately if 30 amps were permitted to flow. Your protection can be replaced with a lower value allowed amperage, but not a higher value.

Can a 30 amp fuse replace a 40 amp fuse on a lawnmower?
You can replace a higher rating fuse with a lower rating provided it works with the device without constantly blowing. So try the 30 amp fuse in your lawnmower and if it doesn't blow and the mower works okay, you are fine. If it blows you will have to go back to 40.
Is a 16amp fuse ok for water heater?
I've never heard of a 16 amp fuse. -I guess it depends where you are. In north America, 15, 20 and 30 amp fuses are common, 40 are also used less commonly. A typical north American water heater uses 2 x 30 amp fuses or breakers. Please write in with detail of WHERE you are in questions like this.
Can I use a 30 amp fuse instead of a 40?
This is not a good idea to do. Sometimes just that little bit of extra current that the 45 amp fuse will allow to reach the 40 amp load might be enough to destroy the device.
How do you replace a 15 amp circuit to a 25 amp circuit?
You have to rewire the circuit completely with 10 AWG wire and replace all outlets and switches with devices rated at 25 Amps. Note 25 Amp breaker is an unusual size. 10 AWG will go up to 30 amps, and that would be the way to go.
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....
How do you turn a 30 amp circuit into a 15 amp cicuit?
Replace the 30 Amp Breaker with a 15 Amp breaker.

My mercury manual says to use a 30 amp fuse for the blower motor however someone put a 20 amp fuse in. Would this cause my blower motor not to work?
The blower motor could stop working if it blew the 20 amp fuse. That's probably the worst that would happen. You should replace it with a 30 amp fuse, if that is what's called for in your manual.
What fuse is for cigarette lighter in 2004 Alero it has a 30 fuse in slot 34 but from what I have read it should be a 20 which is it?
