Electrical Question's, re: sizing Options

[76-914]

Does anyone have a table that shows the amp limits and permissible lengths for various wire sizes? What is std practice for sizing fuses? Is the fuse sized by wire limits or demand? Does a soldered connection add to resistance? (IMG:style_emoticons/default/confused24.gif)

Kent,
That is a good wire table Dave posted. As for fuses, they are somewhat different depending on the manufacturer. ATC type fuses like I used in my fuse blocks are as follows; 125% of the rated amps continuously, 140% for .5 sec, 300% for 0.1 sec.
If I remember right, I had listed some of the most common loads for our cars and the fuse amperage necessary, you just have to search for that thread.
For the stock Porsche/Vw fuses I don't know what they will allow and did not test any to see what they will allow before blowing.
I also use "offroaders.com for some good info.
Soldering should lessen the resistance of a crimped connection , and keep it lower for a longer period of time. Soldered connections are however somewhat affected by vibration and could cause cracks in the soldered connection if the connections are unsupported, ie: hanging loose and allowed to move around.
