Whats Amperage Rating for Fuse Links?

[BrazilBoy]

I have been toying with the idea of going blade style and ditch the fusible links..Anyone know the amperage ratings per color??

5, 10, and 15.

I've used all green fuse links without issue, (temporarily)

 

the fuse link rule is *4 times smaller than the wire your protecting..

 

(these are not calculated only calculated guesses)

 

page 114 in 88 electrical/ service manual

 

 

 

*4 size rule

The smallest I can find in the PAL style fusible links is 20A

A) common wire sizes

B ) their name as a given gauge (AWG=American Wire Gauge)

C)permissible current when used in the engine compartment (176degrees and

D) other areas.

 

A B C D

0.3 AWG22 - 5A

0.5 AWG20 7A 13A

0.85 AWG18 9A 17A

1.25 AWG16 12A 22A

2.0 AWG14 16A 30A

3.0 AWG12 21A 40A

5.0 AWG10 31A 54A

 

Mitsubishi fusible links by color and size. Size shown is millimeters squared.

 

 

Color and Wire Size

Brown 0.3

Green 0.5

Red 0.85

*Black 1.00 (diesel glow plug circuit)

Black 1.25

 

Fusible links are to be two wire sizes smaller than the wire they protect would would mean the following:

 

A Brown fusible link is used to protect an 18ga wire.

A Green fusible link is used to protect a 16ga wire.

A Red fusible link is used to protect a 14ga wire.

A Black fusible link is used to protect a 12ga wire.

Mitsubishi uses these colors, others may NOT so you'll have to look at the wire size to be certain.

 

Fusing current is in older manuals but that depends on how long that high current is present

.3mm is 100amps

.5mm is 100amps

.85mm is 150amps, 15 sec or less

*1.00mm is 160amps, 30 sec or less, or 270amps if 5 sec. of less

1.25mm is 190amps, 15 sec or less

 

Continuous permissible current if:

temp. is 176degrees or less

.85mm is 34amps

1.25mm is 40amps

temp. is 212 or less

*1.00mm, is 26amps

 

*is the glow plug circuit of the diesel engine

If you want to replace fuse links then get a DSM maxi fuse holder, those are attached to the battery post but why? You can have these just the same and sometimes those maxi fuses get stuck in the holder. Why replace with a fuse and a different holder its still there and fuse links last a very long time and can take power surges. You can buy fuse links from many places or just buy the wire and make your own.

Thanks guys I guess I'll make some..I had a brand new set, but somehow I lost them or they got tossed..I figured I could something different and fast as the boys and I are leaving Hawaii in a couple weeks so i am scrambling to get my car done, ship it, and pack....

Roberto, I can't rationalize why you are going to the blade style fuses. If you have clean good fusible link boxes and good fusible links, I think, that the fusible links are better than fuses cuz they will take a momentary current over load without blowing. Unlike a fuse.

 

One old mans opinion. But opinions are like A-holes - everybody has one.

I changed my mind on this Ken....I am days away from getting custody of my sons and being able to move back to the mainland...Just rushed thinking to get my car shipping ready and so on...
