Breakers and Fuses
If the breaker re-trips, you may have too many lamps and appliances plugged into the circuit; a damaged cord or plug; a short circuit in a receptacle, switch or fixture; or faulty wiring. As such, fuses and breakers are primarily intended to protect the wiring -- UL or CSA approval indicates that the equipment itself should not cause a fire
Most residential systems, with fuse ratings such as those used in the above example, are inherently coordinated by virtue of the fuse continuous current ratings ratios. Understanding NEC Requirements for Grounding vs Bonding One of the most confusing areas of the trade continues to be grounding and bonding, which is why this book needs to be in the hands..

What Makes a Fuse Blow? (with pictures)
The big question for me is, will 30amp suffice for 60 year old wiring or should I drop it to 20 or maybe 15amp to keep the heat down? Most of the house seems to operate fine with 20amp, however, sometime during the day (with nothing on) 1 of the systems popped. In the US, a normal house outlet generally has anywhere from a 15 to 30 amp fuse rating (i.e., 15 amps in bedrooms, 20 amps in kitchens, and 30 amps in laundry rooms), so increasing your fuse rating to something above this could cause problems

with the unit plugged in the fuse will pop, so it sounds to me as if the unit is drawing too much, how can this be with these hair thin wires? The wires are nearly 18 ft long could this cause the draw for higher voltage forcing the skyrocketing amps? the only other thing that comes to mind as far as extra electrical current is, The ignitions system is grounded to the boat, which is aluminum, and the unit is mounted to the boat. Take it from me, it's a very lonely feeling to be out on the water and have your boat wiring (in my case, the POS minnkota trolling motor) start on fire
In the early 1900s the Isles' cords were capped with the British Standard 546, or Type D hardware, which actually include six subversions of its own, all of which were physically incompatible with one another. Nonetheless, when Nikola Tesla invented a means of long-distance transmission with alternating current (AC) power, he was doing so in direct competition with Edison's technology, which happened to be 110v

One lamp circuit connects near the AC plug to one of the power wires, and then winds with the power wires to near the middle where it connects with the other power wire. When a circuit is dark, what are the chances that 25 bulbs can be pulled out and replaced and all will make good connection? It is possible to use what I call a "hum tracer," to identify the "hot" side of the AC line as it progresses through the dark string

Why Do You Need a Ground Plug?
In the case of electrical wires outside your home, the electricity flows into your home through the electrical outlet, through the appliance, back into the wall, through the wiring, and back to the electrical line. If you're still running on plug fuses and end up needing your wiring redone talk to the electrician about upgrading to a circuit breaker instead of a fuse box.Dealing with plug fuses is a simple operation
Cigar sockets are fine for low wattage items such as mobile phone chargers etc, but for higher wattages I would strongly suggest gold plated sockets from Maplin. Maplin do not quote current ratings for any of these but I notice that the small terminal posts FD69A and FD72P are rated at 15amps and even the 2mm sockets HF44X and HF47B are rated at 10 amps
electrical - Why would there be a 50 amp plug on a 30 amp appliance? - Home Improvement Stack Exchange
There are a good number of possible speculations about the matter, but the practical point would be, is what I would do, to connect the dryer with a 14-30P cord, but without working load for a work cycle and see if the breaker trips, if no problems are seen then turn it on again now with full working load and wait and see. If you are not confident enough to switch the plug your self to one that is compatible with your supply outlets (and meets the spec for the equipment) then an electrician should be able to do it for a very reasonable price (and he could inspect the used equipment for other electrical safety issues at the same time)
You can easily tell the difference: if you see round, glass topped shapes or small tubes with metal ends, these are fuses; if there are toggle-like switches, it is a circuit breaker box. NOTE: If it is difficult to read the amperage numbers, or if you do not have color coded fuses, then get a black felt marker and, in large letters, write the amperages next to each fuse in the box
Choosing the correct plug fuse
Fuse Power Range (Watts) 3 Amp Up to 700 Watts 13 Amp 700 to 3000 WattsThe power rating for a particular device is usually written on the back of the device or if not it should be in the instruction manual

Why would the fuse in my xmas lights keep blowing?
Hard to make a standard resistive light draw more current than at startup - but you might have one of those flashers that is going south and shorting when it warms up. Split your strings, look for 2 outlets, and you won't blow your fuse(s), which are nobly doing their job from keeping your house going up in a ball of flame

Why do I need an electrical adapter when I travel overseas? - HowStuffWorks
Where a converter would simply limit the amount of electrical output without really reducing it, a transformer actually reduces the voltage of the electricity going through it. If you travel a lot, this can make things very frustrating!The United States and most of the Western hemisphere use electrical systems operating at 110-120 volts
Fuse for my trailer lights keeps blowing
Check the grounds, are the lights harness or body grounded? If it is a harness ground where does it go to body ground and does it connect with the vehicle harness ground? Are the brakes harness or body grounded? Do they have separate or common grounds? Regardless of everything else; if they didn't use a heat shrink soldered connector to connect the magnets to the harness at the backing plates change them now while they are new (even if they are in a junction box,) before the corrosion starts, and check the brake wire routing with construction site travel in mind.

You will usually not lose power throughout the whole house if this happens, it will usually be only one circuit which has gone; check whether perhaps the lights still work if an electrical item has gone out or vice versa. On the box, each of the switches will relate to a certain section of the electrics, for example there will be one for the lights, one for the sockets in each area of the house etc
PAT Testing Support, Plug Fuse Ratings and Values
Modern electrical appliances designed for domestic or consumer use have to be fitted with a BS1363 plug, fitted with the correct cable and an appropriate plug fuse. Of course, the job of the person carrying out the PAT Test (or rather the visual inspection) is to check that the fuse fitted is SUITABLE, not simply to write down the value of the fuse that is fitted! So far, we have two methods for selecting the fuse:- According to BS1362 and the IET Code of Practice we should fit a 3A fuse where the appliance is rated at 700W or less, and a 13A fuse when the appliance is rated at more than 700W
How many things can you plug into an electrical outlet before it catches fire? - HowStuffWorks
Somewhere in your house, you'll find a wall-mounted box, containing either circuit breakers or fuses (found in older homes).Circuit breakers and fuses act as failsafes against electrical overload. They regulate the amount of current -- the volume of electrons moving through a conductor, such as an electrical cord -- which can be drawn from a circuit

voltage - Why does fuse blow up sometimes? - Electrical Engineering Stack Exchange
Why do they blow? Should they? The purpose of a fuse is to protect equipment and wiring against the damaging effects of electrical faults which cause excess currents, and to disable equipment which is faulty. Because a somewhat complex task is being carried out by a deceptively simple piece of equipment (ie a piece of wire) and because the fuse is not always optimally dimensioned for the equipment used, the fuse sometimes "blows" when there is no significant or long term fault condition present

Do I Need an Amp Fuse for My Car and What Size?
If you have two amps that both have internal 20 amp fuses, then you should add those numbers together to figure out the right size for your inline fuse. If you have multiple amps, you can run a single power wire and use a distribution block, but the power cable has to be thick enough to handle the current draw from all of the amps that it feeds.If there is ever an issue with one of your amps, or your amp power cable shorts out, the results could be potentially catastrophic
Why do you need fuses
Semiconductor fuses have ultrafast capabilities because of the sensitive nature of the protection.With new technology, fuses have become less important in the world of electrical power.

How do surge protectors and fuses work? - Explain that Stuff
What are surges? If you've read our long article on electricity, you'll know that an electric current is a flow of electrons (tiny particles inside atoms) carrying energy through a metal or another substance in a loop called a circuit.
