As a general rule, the larger the current rating of the fuse, the larger will be the fuse holder (or at least the metal contacts) because it will have to be capable of handling larger currents without overheating.

Can you replace a capacitor that is smaller in size but same value?

If, by smaller in size, you mean physical size, then yes. You just need to keep the same capacitance and minimum voltage rating. Also, in a power supply filter application, you need to consider the maximum RMS current rating.


What size breaker do you use for a furnace?

It depends on the rating of the furnace. There should be a plate or sticker somewhere on the furnace that shows the rating. If you are just powering a blower motor the rating will be lower than if you have an electric heating element.


How do you change a fuse box to a circuit box in your home?

1. First, find out why the fuse tripped. It could be that you plugged in a heater or drill or saw and caused the fuse to blow. If you know when it happened and what caused the fuse to blow, then go on to Step 2. FUSES DO NOT TRIP FOR NO REASON! A BLOWN FUSE COULD INDICATE A SERIOUS PROBLEM WITH A ELECTRICAL DEVICE, AN APPLIANCE, OR THE WIRING IN YOUR HOUSE. IT IS IMPORTANT TO FIND OUT WHY THE FUSE TRIPPED. 2. Now that you have found why it blew and have eliminated the reason the fuse blew, go to your fuse box. Look for a glass plug fuse with a discolored area that indicates a bad fuse. Some fuses have indicators that show when it has tripped. Make sure your hands are dry, and that the floor around the fusebox is dry. Glass plug fuses have a metal screw-shell base similar to an incandescent light bulb. Try not to touch the metal base as you unscrew the fuse. Grasp the fuse by the kurled glass or plastic edge of the top part that protrudes out from the fuse box. Using only one hand (to minimize the chance of a fatal shock), remove the bad fuse and replace it with a new one of the same size. You cannot mix-and-match--you must use the correct size of fuse. Using a larger size than the circuit was designed for is a proven method to burn down your house. The fuse must not allow more current than your wiring can withstand. Generally you should have 15 Amp fuses for 14 AWG and 20 Ampere fuses for 12 AWG, and 30 Ampere fuses for 10 AWG. 3. If the fuse is a cartridge type, the fuse holder will have a handle or ring. Grasp the handle and pull strongly outwards to remove the fuse holder. Once the holder is removed, you will see one or two cartridge fuses. Using an ohmmeter, check to see if one fuse is bad. If so, replace it with the same type and size. Then replug the fuseholder into the box. 4. While you still know which circuit this fuse controls, look in the fusebox Circuit Directory to make sure the circuit is labeled (showing what and where it is wired). If it is not labeled, get a pen and carefully label the circuit, so that the next time there is a problem you will know where that particular fuse is wired.

Why would the tail light fuse blow after ten minutes of replacement after never having had a problem?

You may have put the wrong size fuse in your car, or you have bigger problems. Fuses are color coded by amp rating. For example, a blue fuse has a 15-amp rating, yellow is 20 amps and green is 30.


Where can you find a 10 amp 125 volt fuse at?

Assuming the wiring is sized for 12 amps, you can replace your fuse with any 12 amp fuse or smaller and with a voltage rating at or above what you expect to connect to it. The amp rating protects the wire, so you cannot go above what the wire can handle. The voltage rating is the max voltage that it can safely protect, so you cannot use a fuse with a lower voltage rating than you expect to connect to.
