How much current (approx) can a normal solder less bread board from Radio Shack handle? I can't find the ratings on their web site.. Anyone that have a feeling for how much I can apply?

Is 2.5 A okay?

 

I'd keep it under 1A. Use a fuse.

 

ive run 5 amps per 'trace' before with complete success. 1 amp is a good rule of thumb though, and should be followed if you value your breadboard's life.

 

Yep, divots are a real pain to work around.
