I think in most applications the difference between 6.3 amps and 7 amps is meaningless. However, if your equipment calls for 6.3 amp protection, 7 amps may allow your equipment to burn up before the fuse blows.
If it means that a piece of production machinery will be shut down until the proper fuse can be found then, yes this can be done. To make the 6 amp fuse a permanent replacement for the 7 amp fuse is not recommended. Using a smaller size fuse may not give the circuit the full current that it needs and may blow. Use the 6 amp fuse if it will hold the circuit on and then replace the 6 with a 7 amp when one is obtained, as the 7 amp is the recommended size from the manufacturer.
No, the circuit is designed to operate with a 2.5 amp fuse in the circuit. By placing a larger fuse than recommended, serious damage could be done to other components that are in the circuit. A fuse closer to the 2.5 amp value could be used for a temporary measure but must be replaced when the correct size fuse is obtained. The real procedure is to find out what blew the fuse in the first place before replacing the fuse with a new one. Without finding the cause it is a waste of money installing fuses and seeing them blow.
Yes they are the same as you have written the question.
No. The 7 amp fuse would allow that amount of current to flow, and the device protected by 1.6 Amp fuse would likely be destroyed if 7 Amps flowed through it.
Yes. The voltage rating is the highest amount of voltage that can be legally applied to the fuse. 120 volts falls well within the range of a 250 volt fuse.
Yes, you can but usually the 250 volt fuse will be physically larger that the 125 volt fuse. You may have trouble getting the 250 volt fuse to fit into the 125 volt's fuse holder.
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.
Yes you can do that as long as it will fit in the fuseholder. It is acceptable to replace a lower Voltage Rated fuse with a higher but NEVER replace a higher with a lower. There are several things to consider when replacing a fuse: 1) The minimum voltage rating of the fuse is equal to or higher than the voltage of the circuit you are placing it in 2) The Amperage rating of the fuse does not exceed the capacity of the circuit you are trying to protect. Always replace a fuse with one that has the same amperage rating. 3) The interrupting rating of the fuse is sufficent for the capacity of the circuit supplying the fuse. If replacing a fuse always use one with an interrupting capacity equal to or greater than the fuse you are replacing.
a 6.3 amp 125 volt fuse a 6.3 amp 250 volt or 300 volt is fine with similar time delays depending on application it may be easier to find a 10A it should still protect most of the components
Sure
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.

Yes, you can substitute a 250 volt fuse in place of a 125 volt fuse. You just can't go the other way around. As far as 1.5 amperes in place of 3 amperes, well, you've got a problem there because the fuse will blow at about 1.5 amperes instead of 3 amperes, so the intended load will not be met. All of this, of course, assumes that the physical size of the fuse is the same. Bottom line is never substitute fuses.
The 5S3.5A125V is a 3.5 Amp 125 Volt fuse which are for the red and black output on the back. and the 5S5A125V is a 5 Amp 125 volt and uses the purple and black side which is also the side the subs on so if you dont have both of each fuses your music will not sound as good
A 15 amp 125 volt outlet is a household outlet.
yes
If the device you are powering requires 7 amps of power, then no. You will need to find a replacement cord with 7 amps. Check the power input requirements of the device to find out.
20 amp on a 12 volt system
absolutely not
