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

Answer 1

Sure, you can replace a 15 amp fuse with a 30 amp fuse, but it's not recommended. The 30 amp fuse has a higher current rating, which means it can allow more current to flow through the circuit than what it was designed for. This can pose a fire hazard and damage your electrical equipment. So, technically you can do it, but it's like putting a square peg in a round hole - it might fit, but it's not a good idea.

Answer 2

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.

Answer 3

If 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.

Answer 4

No. Always replace a fuse with the same type and rating.

Answer 5

Not without moving up two wire sizes from a #14 copper wire rated for 15 amps to a #10 copper wire rated for 30 amps.
