I may be insane. > > Right now I'm using PCB screw terminals, Either use multiple conectors as in car alternators (2 or more 15A spade terminals) solder the cables directly (make sure the PCB traces are wide and thick enough not to fuse!) or mount high curent components off-board and 'cold-switch' them, i.e run control wiring only from the PCB; this has the advantage of moving (usually) heavy and or hot running lumps off the PCB which can be made thinner.You'll also get less voltage drop in the current carrying cables... -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
