You may have big problems. the wiring will overheat if you overload the circuit. The 30 amp fuse won't blow, so you lost your safety device and your house burns down.

If the fuse box is made for 20-amp fuses, the wiring and everything is designed to really only tolerate 20 amps of current. A higher current may cause excessive heat. So, by putting a 30-amp fuse in, you are running 30 amps through a device that has been designed for 20 amps, which could result in a fire hazard.

30 Amp Fuse
2016-09-28 00:15:05 · answer #3 · answered by ? 4 · 0⤊ 0⤋
You stated " have a sump pump that keeps kicking out to reset on its outlet.? What exactly do you mean by "kicking out to reset on its outlet" ? Is it a GFCI outlet that is "kicking out" ? Or is it the sump pump's own safety circuitry that is "kicking out". Anyhow, if the same pump is NOT kicking anything out, and runs ok, when you use an extension cord from another outlet to power up the pump, then that would seem to indict the original outlet as being faulty in some way (maybe an oversensitive or faulty GFCI outlet that needs replacing, etc. Or the wiring in that circuit is faulty. Something may need replacing. ). In any case, replacing a 20 amp fuse with a 30 amp fuse is asking for trouble. A bad idea. By the way, will the original outlet work to power up something else other than the sump pump ? (i.e., maybe try plugging something else besides the sump pump into the troublesome outlet and see what happens, see if the outlet works ok without any 'kicking out'). Another thought, you can buy a cheap five dollar circuit tester/analyzer at hardware store that when plugged into the troublesome outlet will provide diagnostic information about the outlet and its circuit. Of course, if the problem is in the pump itself, and not in the outlet, then the curcuit analyzer won't help. ).

No. There is more than one reason for the fuse being of a certain size. One is that it is related to the ability of the size of cabling in the circuit to dissipate heat without being damaged in the event of a dead short blowing the fuse. 2ndly it is connected with disconnection times for the circuit. How quicky will the fuse blow under fault conditions thus minimising risk of electric shock on that circuit. If this is Britain this is all governed by what used to be called the IEE regs but is now a BS. Circuit design is an essential part of any electrical installation and has to conform to tables laid out in these regulations.

No. Not unless you change the wire from the
fuse to the ciruit. All of it.
If the fuse is larger than the the intended size it
can allow the wire to get too hot. Insulation can fail.
A fire may start.
A 20A. fuse protects #12 wire.
If you go to a 30A. fuse, you need #10 wire.

Please read this carefully. The existing 20 amp circuit has a specific gauge wire connected to it. By law (NEC) this cannot be altered ,and any larger size fuse on the existing wiring must absolutely correspond to adding a larger, heavier gauge wire. Wiring is rated for the circuit by wire gauge: 20 amp uses #12 awg wire. 30 amp needs #10 awg wire. This is important for many reasons, so don't deviate.

you need to be more specific. why do you want to change the fuse? are you having problems? and what is this circuit feeding? the only way you can safely and legally increase the size of the overload protection is if it is feeding a motor load that is having start problems. if thats the case, go for it. if not don't do it.

If you are wanting to change it because the 20 is tripping all the time...then something is shorting out somewhere in that line....or your breaker is going bad. I have had old breakers that tripped multiple times because the shop overloaded them.....after they trip several of times it weakens them. Try just replacing the old one you have with a newer one and see if that corrects your problem.
Sometimes they have multiple wires going to one breaker...so you can fix this by buying the double breaker (with no cross connection bar). It 2 smaller breakers in size only that replace one large size breaker. Once you get the new one you can split off the wires going to the one onto two breakers....without increasing the amp size

No. That line is meant for 20 amps of current. If you run it on a higher amp it may catch fire.
