Q:The choice of fuse tube can be based on the following process

the ambient temperature on the impact of the carrying capacity of the fuse tube, see "ambient temperature".

Q:How to read the fuse ring

four color ring followed by: red, red, yellow, gold. The first color ring red for 2, the second color ring red 2, are valid numbers, the third color ring yellow is 4, said the effective number after 4 "0", the fourth ring is golden, that the error is 5%

Q:Fuses are generally not overloaded.

No limit measures can be taken after the load current has increased.

Q:Why can not change the fuse when replacing the fuse

Change the crude after the fuse does not work, the current is too large, it will burn out the meter

Q:Fuse inspection check how to do?

fuse fuse signal is normal.

Q:What is the significance of the voltage on the fuse?

imilar to the neon bulb principle. Will make short circuit has a current through, to expand the fault. The The But also cause danger.

Q:If it is possible, is it possible to have an electric shock?

The line is too long and the wire Too thin, then there will be a pressure drop! There is the use of this line is too high! I use the voltage meter to find the voltage when the voltage is 170V

Q:Fuse always burn Is the line short circuit yet?

if the use of any of these appliances alone, it will burn insurance, that may be the electrical failure, it was caused by the professional electrical repair division to check the electrical friends

Q:What should you pay attention to when using high voltage fuses?

check the outdoor fuse installation angle changes, points, closing operation should be flexible ; Melt fuse when the fuse tube should be fast, can form a clear isolation gap.

Q:Are there any resistance to the fuse?

Fuse blows and the principle is Joule's law
