The main reasons your amp keeps blowing fuses are a short circuit, faulty wiring, a loose connection, excessive heat, or damage to the power supply or output section or the amplifier.
Overloaded circuits, short circuits and ground faults are all legitimate reasons why your fuses blow on a regular basis or causes for your fuse box to trip out. Other causes could be a result or ageing or faulty wiring as well as power surges.
The correct answer is heat. When current passes through a fuse, the fuse gets heated up due to the non zero resistance. More current means more heating. If the current and duration is enough to raise the temperature of the fuse above its melting point, the fuse will melt (blow).
To prevent the amplifier fuse from blowing we simply need to ensure that the amplifier input power is applied with a soft-start AC input.
30-amp double-pole breakers can handle double voltage (240 volts)—whether as a single 240v circuit or two 120v circuits).
First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through. The result is that all lights, outlets, and appliances powered by the circuit will go dead suddenly.
The main switch in your fuse box is designed to turn off the electricity supply in your property. It`s important to know which switch this is, so you can turn it off in an electrical emergency. Some properties may have more than one switch if there is more than one fuse board installed.
Voltage Rating-Fuses

Most low voltage power distribution fuses have 250V or 600V ratings (other ratings are 125, 300, and 480 volts). The voltage rating of a fuse must be at least equal to or greater than the circuit voltage. It can be higher but never lower. For instance, a 600V fuse can be used in a 208V circuit.

Summary. An electrical fuse is a device that sacrifices itself to provide over-current protection in an electrical circuit. If too much current flows, the fuse wire rises to a higher temperature and melts, thus opening the circuit, but destroying the fuse.
An amplifier that blows the main power fuse immediately after you turn it on or when the fuse is inserted into the fuse holder is usually damaged in its power supply or output section, and will require serviced.
Audio `ground loops` are also a source of this interference. NOW that said, if you are talking about the `ground` being the negative terminal on a DC amplifier intended say for automotive applications, then a poor connection of power through that terminal could indeed lead to overheating and/or a possible fire.
30 Amps, 32 Volts AC.
Key Differences Between 30 and 50 Amps

A 30 amp plug has three prongs – a 120 volt hot wire, a neutral wire and a ground wire – and is generally used on RVs with lower load requirements.

The short-term solution to a circuit overload is easy – move some devices from the overloaded circuit to another general-purpose circuit. Then you can just flip the circuit breaker back on or replace the fuse.
The current from the metal body of the appliance flows into the earth if the appliance is earthed. Then, there will be an increase in magnitude It rises in of current and in turn overloads the circuit. As a result of this overloading or high voltage, the fuse melts.
The fuse wire is always connected in the live wire of the circuit because if the fuse is put in the neutral wire, then due to excessive flow of current when the fuse burns, current stops flowing in the circuit, but the appliance remains connected to the high potential point of the supply through the live wire.
The fuse board and the wires which run from it to the meter, are the responsibility of the property owner. These wires can also be called consumer tails or consumer cables.
If the reading is between 0 and 5 Ω (Ohms), the fuse is good. A higher reading indicates a bad or degraded fuse. A reading of OL (Over Limit) definitely means a blown fuse.
Fuse links are voltage sensitive devices and it is important to note that the satisfactory operation of a fuse link under fault conditions is dependent on the system voltage. Therefore they must not be installed in circuits with a voltage above their voltage rating.
The formula is 30 amps X 120 volts = 3,600 watts.
If current higher than 8 A flows through the fuse, it would melt and circuit gets broken.
Generally fuse or MCB is used for overvoltage protection, here in this circuit, we will build an overvoltage protection circuit without using Fuse. Overvoltage protection is a power supply features which cutoffs the supply whenever input voltage exceeds the preset value.
The current rating of a fuse

This one is fairly straight forward – the current or ampere rating of a fuse is the maximum amount of DC or AC current that the fuse can handle before it will blow. A fuse rated at 20 amps should allow a 20 amp load indefinitely, but if a 25 amp load was applied, the fuse would blow.

I continually get code 90 (low/NO flow) from my 8111. I have disassembled, cleaned EVERYTHING, including the inlet port AT the pump (remind everybody to check this as stuff gets past the filter basket and will plug the pump inlet).

There is No air in the system and I get superb pressure at the outlet, yet I still get code 90. I again removed the flow sensor and put my ohm meter across the flow sensor terminals and activated the flapper and measured an open circuit. I used a heavier magnet to see if I could get make the internals of the sensor move to get an ohm reading, but I get nothing but an open circuit, ie: no measured resistance.

Can I simply bypass the defective flow sensor to trick the 8111 to think it has full flow without damaging the ‘brain’ of the system.?

Intex corp is useless at these questions. They have been out of stock on this sensor for months and are telling me “two weeks” for two months and now it’s “end of August” which I do not believe. Meanwhile I am making no chlorine while the 90 code is showing.

I love the 8111, this is the first problem I’ve had with it, and I’m frustrated that I can not get such an important part from them.

Thanks for listening!

ANSWER : Have you been able to find a solution to this problem. I am having the same issue.

Have a 2004 kawasaki 3010 desiel mule that has worked fine for years with regular maint. then yesterday we started it as usual with the glow plug lights indicator and it ran for a few minutes until we went to take of and it just died. period. we tried to check thing out and finally found a bad fuse in the glow plug fuse holder, changed it with the same size and it ran the rest of the time we needed it and then again today we started and ran it same as yesterday and it worked fine for about 30 to 45 minutes and will out in the field it just quite. i immediately started searching for signs of heat or melting of wire or other signs and found none. the fuse that goes into this circuit is a 5 amp and all i had was a 20 so i said lets see what happens. it immediately blow the fuse without any out ward sign of problems.??????
ANSWER : Replace the glow plugs one or more are shorted

My daughter has a sweet pea scooter that had been blowing fuses and the motor got hot. Im sure the motor is shot. but my question is can anyone tell me if the motor would be the only thing I need to c
ANSWER : Find out whether it is 6 volts or 12 volts and there should be two wires that feed the motor either cut or splice and attach another set of wires with fuse in the line (simular to jumper cables) raise the back tire so it does not touch the ground and place jump wires to the negative and positive of the battery.If the motor moves in either direction without blowing the fuse the motor is good if not then its bad. Uses the same amperage fuse

Vibelife 7117 Error message E1, blowing fuses.
Will not start at first, just gives E1 error message. Leave it paused for a while, then it will start but blows 15A fuse straight away. Have disconnected the drive belt from the motor to the drive roller and fuse still blows with no load on motor.
ANSWER : There is no solution to this problem. Its a Vibelife brand – that’s the Problem! Vibelife is like any number of Chinese, Taiwanese build clones, they are ordered in a batch of several thousand by some dodgy importer and once that batch is sold on ebay or ozauction, its close up shop, order another batch with a different faceplate on the control console and away they go again. In short you’ve got buckleys chance of fixing it so my advice is:
a. Chuck it and get another one of those el’ cheapo treadmills. After all they generally last about a 18 months under normal use and you can afford to buy four of those before you match the price of a professional home use machine.
b. Kind of like above only buy the professional home use machine for about $2600 and make sure is has a 3yr warranty on the motor and control boards. They should last you at least 5 years under normal home use.
c. As for a. but forget buying a treadmill, Invest in gym membership. For about the same price as an el’ cheapo treadmill you could have a year’s membership, all the treadmills you can use and a whole heap of other machinery as well, not to mention the excercise classes you could go to for fun, socialising and general fitness.

ANSWER : Was any of the wires cut through?  Just a shot in the dark, but try unplugging and re-plugging the wire connector going into the clutch lever.  If that doesn’t work submit more information.
